mine is the same except does not start on first crank, i get a little puddle in the bottom right corner of my airbox. someone was saying to me that it was either the turbo seals or the oil rings on the pistons but that i dont know and that was coming from someone who just knows diesels in general not specifically this one so i dont know but i have oil in there too. What is acceptable blow by though?
that is indeed the crank chase breather... remove it from airbox...
it can be turbo still.... but if it works... so what? ;)

Hey there.!

Interesting thread you got here, will definately be following in future ;)
I've always had a weak heart for bimmer's and will probably always have :roll: but until now I only had my hands into the gasoline engines so i have only very little knowledge of diesel engines.

A week ago i got my hands into a cheap E34 imported from Germany with M51D25TU OL also known as the tds engine, this car is only for fun so it will not be driving daily.

So i had some questions and searched the net and stumbled upon this thread which is the closest i have goten to my answers, so i hope you will help out a owner of the little sister to the E28 with M21 :lol:

#1 First of all i read a lot about the head on these M51 engines to fail making cracks in the alloy (is there anyway to strengthen the head so it can take higher boost?)

#2 Next M51 exhaust manifolds design does not fit to what i want to make and the turbo flange is unusable for aftermarket turbo's (will M21 exhaust manifold fit a M51 head)

#3 I have thoughts about if the buyable M20 turbo manifold will fit to this engine or can be modified to do (in few posts before this i read that the turbo will have problems to spool if this is the matter this question is of no use then we want it all to work nicely)

#4 I've gotten my hands into a Eaton M65 twin screw compressor and would really like to fit to run side by side with the turbo (can this be done without a new ECU or do i have to get my hands into a megasquirt.? oh and will the diesel pump be able to feed the engine also?)

Thanks in advance..

I bought the car because we just got a son and this car will be a car we are going to make together when he gets old enough to understand and help :cool: I have no idea where this will end but i will make a hell lot of modifications to this engine and if it blows up it blows up. :roll:

If anyone knows a other place to get help with the M51 engine please tell where i don't want to be in the way if u only talk about E28 :)

1: Reason for cracks... Very small stock turbo and too small exhaust manifold... makes extpressure and heat... usually with evrymod these stock parts are idiotic...

2: m21d24 ext manifold does indeed fit in m51 (i has m51 ext manifold for inspection run in m21) m21 exhaust manifold fits in m51 upside down... this means flange is top side... (if you get m21 manifold... be sure that it is 524TD manifold and not 324TD version with small flange)

3: you can modify those m20 manifolds to fit in m51 but you need to change the flange... ports are in offset and bolts are in different positions (we did this once with one m21)

4: you dont need new ecu etc... (you cant use megasquirt because it is diesel engine) your inejection pump gives about 200hp with evrymod or hammermod
so go ahead use those chargers freely...

btw if you want that your engine works with power... buy an mls gasket from gasket to go and remember update your cooling system...

well.... news...

i dont drive in this summer with my car... too much to do if i want to take it on the road...

in next winter i will make some improvements to it, and some of my old parts will be for sale...

like my intake and exhaust manifolds... old turbo and maybe the injection pump too...

Many thanks for reply this gets things sorted a bit for me :)

So if I improve the flow of the engine it could help avoid craks.. am i right??

I searched danish webs for a used 24td manifold and the only one avaliable atm is for 324 (the flange that is smaller is the turbo flange right?) but i was thinking of making on myself just like you did, i have access to stainless steel tubes which i could weld together and make one with same design as 24td (turbo upwards), i would like to have the turbo fitted upwards to be able to fit a bigger one :lol:

For the m20 manifold, is it worth buying on from new http://static.schmiedmann.dk/ProductPic ... 88_big.jpg to make it fit and will the engine be able to spool the turbo through it? or would it be more reasonable to make one myself? I am thinking of making one that looks a bit like this http://static.schmiedmann.dk/ProductPic ... 80_big.jpg :D

About the ecu, great to know. then i won't waste money on that :rofl: i know about evrymod, but what is hammermod? cant find anything on the web about it!? (which one is the best to use and/or can I use both) how many hp can the 24td pump deliver i was thinking of gettting one to push some more fuel through..! :cool:

Nice MB system btw :shock: was thinking to make a custom bypass valve for my system when i fit the compressor, with a throttle body from a gasoline engine and a actuator. I just dont know how to make the actuator open when turbo starts making pressure.. any ideas how i can make this work?

Awesome and thanks for the link to gasket to go, couldnt find anything about where to get one ;) What do u mean about updating the cooling system? btw its the radiator without expansion box on the side, it has expansion box at center near window which i think is better (had some problems through time with the other system where expansion box is on radiator, leaks, poor cooling and so on :roll: )

Anyway thank you very much for replying this really healped me out and nice project :D

looking forward to see what you are making of the diesel monster and will be hanging around to keep myself updated on things :)

Yep better engine flow lowers the risk of cracking... due to heat

indeed 324td flange is very small and better make a new one by your self

you can use m20 manifolds moddet to m21 but long tubing manifolds make your turbo very laggy, this ones design is good for diesel indeed http://static.schmiedmann.dk/ProductPic ... 80_big.jpg BUT it is for 24v m50 engine

you dont need make any ecu mods... only hammer mod or evry... google hammer mod (it is hard to tell, cause i dont use electric pumps, only mechanical)
but with stock 10mm rotorhead and electric pump 2mm cam plate about 200hp or bit more...

you dont need bypass in your engine... turbo surge is quite tolerated up to 2.5bar but this depends about what turbo you has...

better cooling is that get an very large aluminum radiator like griffin etc.... and i use stock expansion tank.... + i drilled 3x 3mm holes to the thermostat...

but the next big thing is that is has new turbo.... Garrett T04B/E hybrid with my 0.63ar turbine chamber from master power...
and this is fitted to the exhaust manifold and after that is sitting on a top my master power with 0.84ar turbine chamber...

so yes guys... in the next summer... i can boost while i boost.... compound here i come!

well guys say goodbye to ve6 pump... not for the next summer but in next engine.... i just got bosch p-series 113 scania's pump...

it was cheap 250e and it has 10mm plungers... well few modifications and re-sealing + service and it will be good for installing... which is quite challenging operation but done before by other guys...

Like in this Volvo d24td http://harri82.1g.fi/kuvat/Muita%20auto ... /_full.jpg
i have seen video about this car running....

The M50 family engines sit at an higher angle than the M20 family engines, how are you going to do that?

If it does not fit... i will make it fit.... by cutting getrag's case and welding it to the zf's case, like in many other transmissions fitted to totally different cars...

today i bought some parts for the summer and the inspection of the year...
New front stock shocks + top bearings, dust guards and bumps guards...

i will get my coils set in next winter so now need to drive with these

Just got info from my friend who has m3 zf gearbox in m20 engine in he's racing car.... he said that it fits directly to m20 based engines like m21 but in little bit different angle, so shifter is positioned only little bit different

Ya, M20 will tilt the box like 10 degrees....so you have to twist the selector mount and rod a bit and do up a custom trans mount.

I has been little lazy with my biturbo engine project, all parts are in my storage and ext manifold is ready etc...

But old singleturbo engine is now running good and clutch works better than ever.
now im welding bonnet hole shut and modified old intercooler tubes, so now they are under front skirt
little electrics mods are done like kill switch in trunk and soldered joints in 16mm power cable

so at this moment everything almost perfect for next summer

It seems that my car is going to inspection in two weeks, after that it is again on the road...
I will do some mods for this summer still..... it will look more classy 80s tuning soon
-bbs rs 17" replica wheels
-bbs front spoiler
-two 80s antennas at trunk
-silver stripe tape on side (two striped)

I want to go with louver, but i dont have one.... i want window wind deflectors too... but i can only find those for front doors :(

Now intercooler is hidden in front, and hole in bonnet is deleted...
Engine is same old one, but biturbo setup is what im doing for this summer...
