You are correct. Logically it doesn't make sense in a performance sense, but maybe they were taking the passive-aggressive approach by thinking it would be a bad idea to return hot fuel to the tank, which would possibly raise the temp of fuel being delivered to the engine? Or in extreme conditions they thought it might vapor lock on it's way back to the tank. If I had it in my car, I'd probably reverse plumb it.cek wrote:This diagram confuses me.
I thought the FPR end of the fuel rail was the "exit". If that's right then the fuel cooler cools the fuel on it's way back to the tank!?

Re: Noob M30B35 Build. 2014-06-23: I beat the wiring harness
Thanks BuzzBomb. That sorta makes sense.
Even though I've replaced my heater valve I don't remember how the hoses hook up. RealOEM isn't much help and I don't have any good pictures.
This is the new hose, that I believe goes from the outlet (bottom) of the heater valve to the heater core.
1) This goes to the TOP nipple on the heater core, right?
2) This new hose with the hook is too long. I assume I need to cut it even though it has wider sections on the end. Is that right?
3) The output of the head (gooseneck) goes to the input on the heater valve. Right?
EDIT:
I found my old hose. It's clear it was hooked to the lower nipple on the heater core. It's way too short to have been connected to the top nipple.
Does it matter? Logically it makes sense to me you'd want the lower nipple of something that holds fluid to be the "exit". So it is possible that the PO had this hooked up backwards. Again RealOEM and my pics are no help.

I used to work with industrial engines, taking automotive gasoline engines and converting to industrial use. They were also EPA certified and operated with three way catalyst. Cooling the fuel on the return is correct. Once engine has run a while the return fuel increases in temperature, if not cooled in extreme situations can cause to much vapor in fuel tank, unwanted expansion of the fuel and heat the returning fuel to engine. This can cause power de-rate, vapor lock and other issues.

I pulled the clutch off the old engine.
Interesting to see the wetness in there; not horrible, but the main seal was leaking as I suspected.
You'll recall that the REAL reason for this project is Vlad's starter was failing to engage. I had read that replacing the B34 start was such a bitch that I decided to spend a year building a whole new engine instead. Anyhoo, I was curious about how the starter was actually failing. The teeth on the flywheel are fine. The teeth on the starter are fine too. So I guess it is the solenoid just not engaging all the way all the time.
Old clutch. I have no idea if this is 'a lot of wear', 'moderate wear', 'no wear'. What do you experts say? Do people buy used clutches? What's this thing worth?
Lightened flywheel. vs stock E28/B34 flywheel.
It's not super clear in this pic, but the 'lip' for where the PP touches is maybe 1/4 a millimeter. This shows it better.
I'm still going to take both flywheels to my machinist and have him help make the call, but I can't believe that much material will have an impact on how tight the PP holds the clutch.

Re: Noob M30B35 Build. 2014-06-23: I beat the wiring harness
On the fuel cooler. If you want to move heat from the fuel to something else it works best to do that on the hottest fuel with the greatest delta. That would be the return.
On the flywheel. I suggest again you put it on the crank with old bolts and snug it up and check runout. If the runout is minimal then work with it but if it's excessive you have a problem that won't go away regardless of what you do unless you machine the whole friction surfacr flat and rebalance. My biggest intial fear was runnout then the surface finish then the step. A new clutch probably means step is not a ig deal and you might get a liitel less life. There should be a spec for thickness on an old disc and yours does not look too bad. I'm thinking it has been replaced and the old flywheel also machined sometime reducing the step. I think this is common.
Not sure your machinist can check runnout as well as you can bolted to the actual crank. The precision and quality of a BMW crank is outstanding and the mounting surface of both parts should be very clean when going together.
Looking good.

Congrats. It looks better in the car than it did on a stand.
Spec on a new clutch is 10mm. The discs really never seem to wear out. Pressure plates get old and stuff but none of the BMW mechanics I know have ever replaced a clutch on an M30 due to wear.

No the valve cover is not bolted on. There's no oil in there yet (just assembly lube). I'll be putting in special break in oil, running it for 20min, then final torque of head bolts and a check of valve adjustment. Then new oil. Then drive.trevmmeister wrote:Is the head cover even bolted on?

Coil.
The B35 coil is different than the B34 coil and the B35 plugs want you to mount it near the firewall.
I've seen others do this with custom brackets and with just bolting it to one of the nuts that holds the fuel cooler lines.
From the donor 735i grabbed this bracket, which I had thrown in with everything to get zync plated. I didn't remember what it was for, and I can't find it on the 735i diagrams on RealOEM, but I'm assuming it was the bracket that held the coil in place on the E32.
I bent it 90 degrees and I have three choices of where I can mount it.
One, on the firewall; either using one of the studs that hold the insulation in place or with some self tapping screws. This will be the easiest to mount and mostly 'out of the way'. Downside it it will be lower and thus closer to the headers; heat might be a concern.
Two, right above where the fuel cooler lines are held to the fender. This will be relatively easy to mount; two self-tapping metal screws/bolts. Downside is it will be a PITA to get to #5 & #6 spark plugs.
Three, farther to the rear; even more out of the way. But getting a drill in there to tap the holes for screws will be impossible.
Any thoughts or suggestions?

Re: Noob M30B35 Build. 2014-06-28: Engine is in!!!
Hmmm... New AC belt is too short. Somehow I got a 13x810mm belt (I believe from Blunt).
I'm using the B34/E28 compressor.
RealOEM calls for 12.5x800mm for the E28 and 12.5x855 for the E32.
The 865mm long belt I have for the PS pump is WAY too long, so the E32 belt, at only 10mm smaller will likely be too big too.
Can you buy belts in arbitrary lengths? I figure 820-845 will be about right.

Re: Noob M30B35 Build. 2014-06-28: Engine is in!!!
The M30B35 Swap FAQ does not explain the whole air filter housing thing very well.
It appears the choices are:
Use the B34 housing
For now I'm going with the orignal B34 parts just to get running. This is muy disappointing.
Lots of stuffs hooked up this afternoon. Wire harness (mostly) wrapped (see previous post ). Coolant hoses mostly in place. Etc...
It appears the choices are:
Use the B34 housing
- Must use B34 rubber boot between the AFM/MAF and throttle body.
- Can't use B35 valve cover mounting points for AFM, but must mount AFM to B34 air filter housing bracket.
- Looks oldskool next to the the modern B35 motor and hides the sexy powder coated B35 valve cover.
- Requires heavy modification to the filter housing mounts welded to the fender, for which I can't find any pictures or instructions about.
- Uses mounts on top of valve cover.
- Sits so close to the valve cover that it actually rubs on the spark plug wires. Bob (Das Paracutefarfugnugen) had his #1 wire wear through.
- No obvious way to make it 'fit' to the headlight backing.
- Looks factory and better looking compared to the E28 housing. Sexy powder coated B35 valve cover is visible.
- All the 'experts' say these filters are crap and the world will end if they are used.
- Must spend $$$ on fabricating tubing a heat shield. Some say TCD carries a kit, but I don't see it on the site.
- Looks sexy as hell (but not OE) compared to the E28 housing. Sexy powder coated B35 valve cover is visible.

Re: Noob M30B35 Build. 2014-06-28: Engine is in!!!
I just realized I never got back to you in regards to the airbox, so here's a few pics of how I did it in my car. Apologies for the poor lighting, I need to replace the fluro's in the garage. I should also make it noted that this install was only ever intended to be temporary until I installed the new engine with the ITB's, so the quality of the bracketry and the fitment in general isn't something I'm proud of, but could be improved easily with a little intuition. Apologies also for the appalling state my engine bay is in at the moment. Hasn't received any love for a long time.
Anyway, I made a simple bracket to mount to the side of the box using the factory rubber at the top, and mounted to the OEM coil location on the bottom. The underside of the box sits on another small T shaped bracket which mounts to the frame rail through a small hole that's otherwise unused from the factory stamping. I can remove the airbox and take a picture of that if you need. The bellmouth sits nicely just below the RH high beam, and has a decent flow of air from behind the headlights. If it were a more permanent install, I'd have included a small plastic guide to direct the air from behind the kidney's. The first three plug wires are no problem provided you wrap them in cloth tape, or some of that curly hard plastic stuff you find on home appliance cords otherwise they will eventually chafe on the airbox heat shield, as it IS a tight fit. I also put a small piece of adhesive loop sided velcro on the body to prevent the aft airbox clip from chafing the paint, due basically to laziness. It doesn't touch the body as it sits, and would clear easily if Id made the lower bracket a few mm taller but I didn't care enough to properly amend it.
I also mounted my B35 coil to the factory bracket left behind after the M20 coolant tank removal. Works nicely, and isn't too close to the exhaust manifold however I'm guessing you wont have this bracket.

You need something like one of these kits and an innexpensive import works fine. I think mine came from Enco. The mag base goes on the block and you adjust the arms so the lever or stem runs perpendicular to the friction surface. Rotate the flywheel looking for changes. It would have been easier still out of the car but too late. These things are also ideal for checking hubs and rotors btw.
Bentley says maxiam axial runout is .1mm (.004") at outer diameter. Personally I would try to get it to 1/2 or less since whenever I've measured one before removing it is almost undetectable runout.
Also a quote from Bentley says "If the flange height has been reduced to zero clearance during machining, the flange surface of the flywheel must machined until some clearance exists. See figure 5-6. BMW does not list the specification for this flange height." I guess we need someone to measure a new flywheel to give guidance. I would try to replicate the flange height of a new flywheel.
Bentley also says the minimum flywheel thickness for a 535 is 26.5mm (1.043") and I think yours is now much thinner than this. What does that mean? My guess is too thin results in hot spots and warping. This is another reason to avoid the way that flywheel is machined as I think hot spots develop in the areas of less mass, every 60'.
But I really don't know from experience what happens.

Re: Noob M30B35 Build. 2014-06-28: Engine is in!!!
I've got the airbox positioned closer to the valve cover due to the extensive washer bottle relay preventing it from moving across further, as you can see if you look closely. With the old regular washer bottle in there, it was a much better fit with the bell mouth positioned nicely between the two headlights, and a fair bit more room between the plug wires, as per kzolee's pic. Again, if I'd intended on the fitment being permanent, I'd have relocated the headlight washer relay to allow a little more room.
Re: Noob M30B35 Build. 2014-06-28: Engine is in!!!
Before you continue, test fit an 02 sensor into your new bung, and make sure the probe reaches fully into the exhaust stream. A drivability problem was recently solved because of a bung that was too tall, keeping the 02 sensor from correctly interpreting the exhaust gasses. I know it sounds crazy, but I wouldn't believe it either if I didn't see it for myself.

Just realized I'm missing the cable that goes from the (+) battery terminal to the starter.
Oops.
Now where did I put it?

This morning was all about the transmission.
My son was supposed to help me, but he got invited up to some shindig on an island and left early this morning. Good thing he left two of his buddies at our house. They helped me get the transmission on the transmission jack. My back is not capable.
They also helped me test fit the transmission to ensure I could get to all the bolts with the socket extensions I have on hand. I can.
I'd never installed a clutch or transmission before so I took my time double checking everything (and Bentley's). Those of you who are master-class probably could do what I did in about 20 minutes, but it took me about half a day.
Got the short-shift kit assembled.
Doing it was a bit of 2 step forward 1 back. Notice in the pic of the transmission above the direction the long side of the shift-rod bushing is pointing? That's backwards. The guy who replaced the seals on the transmission put it on backwards. I couldn't figure out why the shift-rod wouldn't fit right. I looked at my old photos and saw the thing pointed the other way and the shift-rod went on the right. I then figured out how to get the bushing off (remove the ring that covers the pin, push the pin out).
I also had trouble with the UUC bushings for the shift lever end of the rod. They wouldn't fit (I'm glad I took my time and did a test fitting; it would have sucked to discover this later). A little emory paper on the end was all it took.
The B34 has two flywheel reference sensors that attach to the tranny. The B35 does not. I didn't like having those holes uncovered so I went to Ace hardware and bought a collection of caps that might fit. The rubber stoppers would have worked no matter what, but they would have felt ghetto so I was hoping...
The plastic ones with the 3 ribs fit perfectly. Heh.
Next, following @tn535i's advice on testing the runout on the flywheel, I hooked up my new indicator (always love an excuse to get a new tool!) and measured (using old bolts so that the loctite on the new ones would not be used up). The runout was hardly measurable (+/-0.010mm).
Clutch is in.

Doing #8 before installing the trans will make make your life a lot harder. Once the trans is bolted up and before raising it to installed level, drop the shift lever down through the tunnel and secure the ball lock ring, along with the linkage. Then backup light wires. Then clutch slave. There's a lot that is easier to do while the trans is still suspended and not raised and the crossmember fixed to the chassis.

Rear header in. Taking a break because it's exhausting work reaching overhead. I can't imagine what a PITA this would be without a lift.
Pro-tips for installing headers (I wish I had known these when I put them in last year):
Pro-tips for installing headers (I wish I had known these when I put them in last year):
- Use shorter studs. I find 35mm is perfect for the IE headers. See pic below for how perfect they fit. This makes getting the headers on/off much easier. It also improves access to the nuts.
- Turn steering hard to the left.
- Remove cross-member.
- Remove heat-shield that covers the LHS trailing arm mount to frame.
- Use a mini (1/4") ratchet. Have several lengths of extensions. This will let you get to all the nuts with little fuss.
- Do the rear one first. DO NOT put both headers in and then try to tighten nuts. This was the biggest mistake I made last year! Duh.

Nice Nice Nice. Everything about this project is looking Nice.
I'm not sure what you may have missed (if anything) and what I have probably just missed reading. Right now my only thought is do you have the special moly based grease to lube the splines on the input shaft?
Thanks for keeping us up to date. Waiting to hear it's running.

This really does look great. The red engine bay really accentuates everything nicely.
