FUBAR 528e, Gauging Condition of the M90

[LeiseyJr]

Solid gains. Are the gains in ignition timing?

Yes ignition timing is everything. Mainly what your paying for in any tune is the ignition map.
BMW or BOSCH cut it pretty hard in that area on the stock euro DME looking at the .bin I have.

[LeiseyJr]

Update.

The camshaft begin to fail around October...? Tracked it in August and oil pressure light was coming on at idle. Glitter upon oil change.

TLDR changed oil pump and the whole cylinder head. Got oil temps too hot and valve spring pressures were too high and eating camshaft alive. Brand New schrick Lasted 2 years and 30k miles.

Car was down for awhile. 1-1.5 month? Someone gave me an e46 330i 6 speed for free. So daily'd that until I finally found a b35 camshaft. Cylinder head is now all stock components. B34 head with b35, cam valves and springs. But all stock stuff, rocker arms, no rocker locks etc.

It doesnt really feel down on power still feels quick.

Had a blast with it at TexFest.


Other than that car is pretty much the same. Still doing track events with it. Did two in November, and two this month.

Last event while trail breaking, LF strut housing failed. Tore the tube.

So that is now repaired and reinforced. Found a Koni was blown so that was replaced with my old Bilsteins.




So idk what I plan to do with car now. Still daily it sometimes, forcing myself to drive e46 more. Shell is cracking in a lot of places. Cowl is cracking, bulkhead is cracking, b pillars are cracking.

Pushing this old shell hard with probably 300k on it. Current plan is to keep band aiding it together and keep driving it.

School has been hectic. But still making progress there. Have a full time job at NOV and I moved out with my girlfriend.


Will probably follow this post with picture dump. Have to remember Flickr log in and all that. but for anyones curious, I still own it. Still being used, broken and repaired.

[athayer187]

Pics of the failed strut tube? Curious to see what failed and where.

My opinion - drive the crap out of it. You're having a great time, fixing what needs to be fixed, and likely embarrassing cars worth 10x or more what yours is. It may never win a beauty pageant, but it sounds like it still puts a smile on your face.

Props to you! Learn me your ways on fun time management.

[LeiseyJr]

Still locked out of my Flickr. Update.


I had some major breakthroughs in terms of lap times. Finally got the car down to the 51s, it is just a 1:51.9 but still a 51. I got some Toyo RR takeoffs and a rabbit to follow this is what I needed to push just a bit more. Didn't get go pro footage of a full 52 before go pro died or the 51, but here is some of the 52 behind my friend Chris in his Z3M.

Here is footage tho:
https://www.youtube.com/watch?v=hOYxH2NZAvw


My goal is still a 1:49.9. I have talked to some drivers I really respect. There is still another second in driving and getting the perfect lap. No one knows where the other second will come from without adding lightness, grip or power. Maybe a set of sticker tires and a cold day?

I will keep pushing, the cracks in the chassis don't look like they are spreading yet. Once I can consistently get in the 51s, or 50s. I might consider another modification.

Engine seems to have survived the weekend?

I did make some tuning changes and seem to be keeping up with my friends e36 m3 a lot better. Also have a lot more low end torque for around town. So very happy with that. On the straights we were about even, I was also maybe in his draft. So could be illusion of that.

Other things that have happened:

car got rear ended, euro bumper got a bit mangled so cleaned up my spare set super happy with how it came out

brand new nissen radiator

Genuine 1982 E24 Recaros, I found a set getting one reupholstered right now for passenger. O bought them for instructor training school with PCA, wanted a set of matching seats that were easy to get in and out of. These seats are also somewhat sentimental, update to follow.

I post updates pretty frequently here:

The TLDR of all that is my oil cooler setup is really janky. Leading to it pushing ac condensor into radiator. It's all deleted and good now, but that's why that happened. One day I will redo the oil cooler not like a fucking monkey.

I actually made it to Instructor with PCA, which is a big thing. There were some who didnt make it that weekend we did the school. The driver recaro is at an upholstery shop. I was redoing it so Id have a brown cloth passenger seat. So far they have made ZERO progress on that but as you'll see reading haven't had time to worry about that. However in July I will need to just cut losses and pick it back up.

At some point went to Radwood
Untitled by Kurvenkamph Motorsport, on Flickr

Car did another event, this time on the RRs. Made a new PB of 1:51.9. Still two seconds away from my goal of 1:49.9. Glad to finally break the 53s. A lot of people are doubtful of it getting there, they think I'm wheeling it pretty good. Hopefully weather, setup or a line change can deliver that extra 2 seconds. Here is some footage I have following buddies Z3M that day.
https://www.youtube.com/watch?v=hOYxH2NZAvw

The oiling issue is REALLY bad on these tires. So my dad fixed that, we copied something that I found online. He did a fantastic job. Basically the oil will hit the baffle and drain out the holes instead of being ingested. If you don't know what I am talking about, here is a link.

This baffle gets JB welded to the plate in the VC.

Then junkyarding happened got some great parts off this 1982 eta.
-Lowish mile steering box
- good used original draglink

-spare heater valve that says made in germany
-VERY healthy fan clutch

I am going to Atlanta in less than two days as of writing this to drive with Jayjaya29 at Road Atlanta. I got a chance to do a test day on the third. It did another 1:51.9 on my first hot lap!!!!!

It then however decided to have a super sick intermittent electrically issue. Car was killing spark mostly at idle when hot randomly. Could not replicate the issue by wiggling anything, hoping curbs etc. That day I swapped, reference sensors, coil, main relay and ecu.
Later I swapped the entire engine harness and it still didn't do shit. It ended up being the fucking AFM. I didn't want to admit that one was bad becuase that afm spring setting were really good. Luckily I have a spare so what is in car right now and all is well. Also deleted the OBC relay and burned Miller tune to 24 pin chip so I can go back to using my reman ecu. Rule out those failure points as well.

My friend has been working hard to make the AC right on his volvo. The legend bought a 30lb tank of R12 for his Volvo. I was a bad influence on that one. Luckily after we did a parallel flow condensor, aux fan, and he sourced a parallel flow evap for in the car. It is cooling VERY well with R12.
Yeah by Kurvenkamph Motorsport, on Flickr

With my upcoming 13 hour drive to Road Atlanta, I figured it was time to stop being a bitch and fix my AC. So in 5 hours had the box in and out, and that was with driving around doing errands and all that. Sherman gave me a known good airbox from his wifes old car that was scrapped due to rust. I knew that car had good airflow out the vents, mine did not. Blower is worn out and evap is clogged. My plan was to rebuild this one, but sometimes don't get it right. Just get it working. Car had airduster in it right now as freon performance is okay, but with lack of airflow pretty miserable. We had all the gauges, R12 and tools there.

Yeah by Kurvenkamph Motorsport, on Flickr
Yeah by Kurvenkamph Motorsport, on Flickr

So swapped it out (the duct tape is nice right). It really wasn't as bad as I remembered on my dads car. Car is cooling very well even with no tint, even my girlfriend says its comfortable. With 98 ambient I am comfortable in the car. System is mostly original, so quite pleased with that.I don't even have to run blower at 3! Not sure how long it will last but when this breaks. I am just going to replace everything with stock components and using R12 again.

Picture of testing, before console reassembly. This known good box of course had a bad resistor. Speed two was broken. So swapped it out for my old one and we were in business.

So yeah that is the update. Hope you enjoyed if anyone is even still reading this. Need to pack the car and head to Atlanta.

I am still daily driving car as long as there is no rain (bald tires). I put 15,000 miles on it last year. Still need to go back and fix some more rust, hopefully the new parts car can donate the metal though. I have a lot of sentiment still towards this metal fatigued shell and the right euro slicktop one hasn't come up yet. So I will keep driving this bitch.

Alright so I did a shit job keeping up with the updates of this car. Did an okay job documenting it on the Instagram, follow me on there if you want better updates. @sam.the.jam

Anyway, the Vintage 2023 happened. What a roadtrip, 5 days and 2689 miles. Two cannonball trips to and fro, Tennessee to Houston and North Carolina to Houston. The rest of the 3 days were busy too. Had the pleasure of doing the trip with my friend Ryan. Absolute treat.

We cannonballed it in one day from Houston the most Southern city in Tennessee, so we could deliver some rare Mercedes stuff. Then headed back down to see Jay, our gracious host and a good friend.

IMG_3716 by Kurvenkamph Motorsport, on Flickr

We had some extra time before Vintage so we went to see a large stance VW meet in Helen, Georgia.

I didn't pay for any track pictures as money was pretty tight. Learned that modern 200tw tires are really good. Retiring from using Toyo RA1s as my street tires (RE71RS) I drove up on were 2 seconds faster. Which was still slower than the car was on the Toyo RR takeoffs from last year. Alas it was a damn good time, no mechanical issues at all besides for the A/C acting up on the way back home. There were some casualties, fog light delete, turn signal lens and a centercap went missing.

Had the most fun I've had in a car chasing this ZHP:

Glad you made The Vintage trip.
It'd be nice to figure out a caravan next year w/ Ryan in Casper.

[LeiseyJr]

I am not big on maintenance however, before doing a big trip or track event. I like to do what I call a "nut and bolt check", this is jack the car up ,check all fluids and put my hands on all the fasteners. Just get my hands on everything and make sure no glaring issues or thing beginning to fail.

In the next post I will share, you'll see the trip I was preparing for. However, I noticed something odd.

IMG_8431 by Kurvenkamph Motorsport, on Flickr

That looks a lot like a crack....

After some brake cleaner...
IMG_8432 by Kurvenkamph Motorsport, on Flickr

So I headed to my parents house to use my dads welder and lift. Sure enough...
IMG_8450 by Kurvenkamph Motorsport, on Flickr

Since the genuine BMW M5 mounts go hard to get, I finally made the plunge into aftermarket motor mounts. So instead of my fuse being the mount, it was now my subframe. This subframe was already reinforced for the steering box so I wanted to repair it if possible or die trying. I had a spare front subframe just in case as well, and a junk one I think I got from when Sherman was clearing house.

I only had a day to do this repair, but I knew it needed to be stout. So I sacrificed the junk subframe to fix this one:

IMG_7495 by Kurvenkamph Motorsport, on Flickr
IMG_8459 by Kurvenkamph Motorsport, on Flickr

So I welded in the broken piece, and grinded it down. For a less spiritedly driven car, I think this would've been good enough. However I am a monkey, so I wanted to reinforce it.

That is about 82 miles from my house one way, so I wanted to take care of my cracked rear floor pan that I have been ignoring for a couple years or so. Reinforce that before he moved. One of the skills I don't have is knowing how to use a Mill or Lathe, well I can it just won't be precise or pretty.

He made a reinforcement plate for me, using an old Diff mount I had a template. I don't change the diff mount often, probably once every 3 years. When I went to replace it last time, I noticed some cracking around the bolt holes. Since then I have pretended I didn't see that. I am not that happy with this reinforcement but at least it is a reinforcement not a repair.

As I'm sure some of you can clearly see, I did not grind away enough undercoating. Which I found out the hardway.

There would be many things I'd do differently if I were to do this again. However I think it's reinforced.

Still catching up on updates but Road Atlanta Trip has 3 parts, so here is part one.


Absolute beautiful drive up to Georgia. Typical one shot strategy, this time I was solo left at 3am. Was able to arrive there with daylight left. I did not bring the right tires to set any records but a blast of a weekend, did every session I could.

I did all my red group sessions and car was doing great, tires were spanked but I wanted to squeeze out one more session.

Engine went boom. I am very far from home, engine isn't repairable. I need the car for my capstone so it can't be left in Georgia.

Second Road Atlanta Trip for 2023 (2/3) So I have never really towed before. So naturally a rented box truck and trailer is a good idea. Uhaul giving me a trailer with a bad tire and no lights hooked up, and then dicking with me for 2 hours was not paticulaly fun. Thankfully Strictly German was 5 min away from Road Atlanta, so I went shopping for a new engine and just to see the empire. It was quite an incredible place. Hopefully I can go and meet Bobby and his team again soon. Long story short, I ended up spending another hour finding out I had to go to Gainesville to get it sorted. After losing 4-5 hours, I decided just to stay the night again at the Lane’s. Helped @jayjaya29 do his gas tank which was a good time. Woke up at 3AM in Georgia, and cannonballed home. Basically just used the 75mph speed limiter as cruise control, got a dead flat from some road debris. That was only a 2 hour delay luckily. Eventually I ended up at @thachileandude to drop the car and it’s new engine off. After all was said and done ended up home around 10pm.

Second Road Atlanta Trip of 2023 (3/3) Just want to preface, I can’t thank @thachileandude enough for letting me total his shop and being there to help swap in the new heart. Without that I couldn’t have gotten the car running a week after it blew up across the country. Which I needed to do since my senior project uses this car. It was my first time dropping an engine from the bottom, can’t say I enjoyed it too much but good to try new things. I had pretty good faith in this M30, looked like it was taken out of the car it was last in and someone cared. They went through the hassle of painting the block and all the letters, new timing chain parts and in general was super clean inside. There was some fiddlefuckery with marvel mystery oil and compressed air for some corrosion on the valves from sitting. It started cranking evenly and the compression numbers came up to non abysmal levels. Still wasn’t 100% sure if it’d be good but didn’t have a choice but to carry on. The old motor was completely sacked out, besides the timing failure. Burning all the oil and discovered the thrust bearing play on removal. Took the entirety of the weekend to swap it out, but made the 50 mile drive home right after being swapped. Hopefully the new mill will be good placeholder until after I graduate.

Good noises after a long weekend

If you wanna read more about the engine failure and see where I will update it when I found out what blew up

Went to a local BMW shop that has been in business for over 40 years.

Unfortunately I have a problem and noticed this engine sitting under a carport. The port welded on for EGR(?) for federalization was my giveaway, to dig deeper.


IMG_2143 by Kurvenkamph Motorsport, on Flickr

Sure enough it is a 1981 Motronic M30, so I bought it and took it home

Guessing you got it for a steal! Bonus you have the oil cooler filter housing already there. Looks like the '81 M90 to me (without the raised water jacket).

Are you going to try to run it on M1.3?

Yes that's exactly right on the non raised water jacket. Still really weird to me it has a E28 based pan on it, but it looks like it has never been off.

It has a new head on it, looks brand new in there. It compression test at 180 except for cyl 1-5 @ 160 they have very minor surface corrosion in the bores. Guides might be original. I paid $1000 for it, which I think is fair as I only knew it turned over when I bought it. Didn't realize it had a new head and good compression until I took it home.

It also came with a lightweight flywheel core. I have a E28 M5 Oil Cooler setup that I need to install in the car, I went back to no oil cooler. Wasn't happy with the lines on the 745i one.

I will not be running it on M1.3, I am very comfortable with M1.0 so I want to stick with that. I probably need to sell the M1.3 stuff that is collecting dust in my attic.

Took the VC off and was praying it would look decent. Was greeted with this pleasant view.

Everything is incredibly clean in the top end.

After some more digging it definitely had a head put on it, as there are signs someone has been in here. Gasket sealer, painted rear cover, missing bolts, and new exhaust manifold gaskets.

Drained the oil and checked the filter, no glitter. Compression test was good as said in the previous post it was 180-160. I have access to a leakdown tester but with the numbers like that not too worried about it.

Looking at the engine and things replaced on with date codes, ignition parts I believe it has been sitting since around early 2000s. Newest date code part on it is from 1999.

Ideally I'd do the headgasket as preventative, but they are very hard to get. Just gonna throw this in and see how it does.

Before I throw it in, I did need to track down some obscure parts. I will go over that in the next post.
