I just purchased 16 lifters from Denis.  I sent the $ via PayPal on Friday night and they arrived at my doorstep this afternoon!  How's that for service!

I certainly wish all of my on-line transactions were like this!!

Thanks Denis!

Engine + Driveline / M20 flywheel conversion - starter question

« on: September 06, 2008, 09:04:31 PM »

Is it possible to just use an M20 starter?  If not, are there any directions on how to swap the pinion gear from the M20 starter into the M42 one?  I can't seem to find any online.

When I spoke with Ted / Teddy at Metric Mechanic, he informed me that they could swap the ring gear from the M42 dual mass flywheel onto the M20 single mass flywheel.  However, I believe there is some amount of machining of the Single Mass Flywheel required(I may be wrong on this).  If I manage to get my M42 rebuild done (currently waiting on new Pistons, enroute from Germany), I think I'll take the easy way and have Metric Mechanic swap the ring gear for me and I'll be on my way....  

Which ever way you go, good luck!

Engine + Driveline / Just R&R'd my Timing Components

« on: August 23, 2008, 12:22:10 AM »

I only wish I were just doing the timing CHAIN...  I've got a full rebuild in the works...

peerless, What is this liquid gasket sealant that you recommended?  I may need some advice as well...

Petebee, sounds like you did a nice job.  I only hope my rebuild works out just as well.  I'll need all the luck I can get with this job.

Well, Happy belated B-day to swiss...  I got you beat... I was born in the 60s (makes me an old fart...  :p )

So, do you have pictures of the Swedish girls that you wish to share???

Engine + Driveline / MarkD Chips - Questions

« on: August 23, 2008, 12:04:30 AM »

I've not done it yet, so someone can correct me if I'm wrong, but you basically need to source an M20 single mass flywheel, clutch and pressure plate(not sure if you need the Throw out bearing)

Once you have these, you then have two options to match up with the starter:  either purchase the correct starter gear to match the M20 flywheel or you can have the ring gear removed from the M42 flywheel and mated to the M20 flywheel (Metric Mechanic can do this for you)  If you go the Metric Mechanic route, which I will most likely do, they will machine some of the excess weight from the single mass flywheel (I believe down to 11 lbs).

Of course, I didn't research this issue for my '91 318iC before removing and replacing just about all of the suspension and driveline components.  So now I have my dual mass flywheel, along with a new clutch.  Of course, I have bigger issues to tackle at the moment (spun a crank bearing and rod bearing..:eek:, so I'm rebuilding it....)

Good Luck with your decision on this.  And, BTW, welcome to the M42 club.  You've definitely found the right spot for your car.

P.S.  Where are you located?

M42 Reference / Hartge 2.1 M42 or M44?

« on: August 19, 2008, 11:23:10 AM »

Definitely looks nice!  I can't really read German, but the description seems to indicate that this was a 1.8 liter engine from a 318iS.  From what I can see, it's basically a shell and that you'd need pistons, valves, cams, etc...

You guys over in Europe always get the goodies when it comes to BMWs!!  :mad:.....

Cam sprockets seem fine.... what about the crank sprocket?  The Cam sprockets on my 318iC were fine, but the crank sprocket had some very sharp teeth and will certainly be replaced when I rebuild it.

Engine + Driveline / Uh Oh....Engine making bad noises...

« on: August 13, 2008, 08:58:34 PM »

I have the pics on my camera, but I haven't had a chance to copy them to my computer.  I promise I'll get them up as soon as I get a chance...

As for a engine, I have another M42 that I removed and completely disassembled from a "rust bucket" 318iS.  I'll be using the block and crank from it.  I'll have to sort through the Con Rods to find the "best" four.  I've been in touch with Metric Mechanic and will be using their Crank and Con Rod bearings (thanks to the tip from colin86325).  I now know about this weak spot with the 180 degree thrust bearing vs. 360 degree Thrust Bearing.

So, everyone can wish me luck with the rebuild.....  Any hints, tips or suggestions are welcome.  I've heard the upper timing case cover is a "real joy" trying to compress the profile gasket...

stay tune for pics of the damage...

Cheers,

OK, well yesterday I finished disassembling the engine and found that I had spun a Con Rod bearing as well as a crank bearing :eek: (4th from the front w/ Thrust bearing).  When I removed the shell from the block, I found a nice notch / scratch in the block...  I don't have any experience with this, but I'm guessing that there's nothing a machine shop can do with something this wide or deep.  If I get a chance I'll take pictures of everything that I've been looking at.

If anyone has any insight as to what extent a machine shop can work with, I'd greatly appreciate any insight you may have.

Thanks!

Wait a minute...  did you get rid of your 318iS?  : (  That certainly looked like a really nice car.  I've never driven an E21, but I've heard they don't handle as well as an e30.  Whatever the case may be I certainly hope you enjoy it.

Engine + Driveline / Update...

« on: August 05, 2008, 07:35:28 PM »

Well, I've removed the upper oil pan as well as the upper and lower timing case covers.  Whilst everything's intact, the sprocket on the crankshaft definitely has some sharp teeth and will most certainly be replaced.  But, I bigger issues at hand.  It appears as if the metal shavings made their way into the oil passageways in the block and ended up in the crankshaft bearings.  As a resulte, the added friction seems to have caused at least one of the crankshaft bearings to spin...  And, from the little I could see, it appears as if the crankshaft has been scarred...  Looks like I'm going to have more knowledge of the internals of the M42 after all of this is done...  Wish me luck!

Thanks..  I pulled the valve cover yesterday afternoon and everything seemed to be intact.  I spent this afternoon removing bits in order to make my way in to remove the upper and lower timing case covers.  I also removed the oil filter, of course there were plenty of little metal shavings in their....:eek:  Once I get all of the bits off and remove the timing case covers I'll know better what I'm up against.  

One thing I'm searching for now is a diagram of the oil flow.  Specifically, does it come up from the lower pan, then through the filter before it's delivered to the rest of the engine?  If so, then I'm hoping that all of the little metal bits stopped at the filter and not distributed through the rest of the engine.  I'm sure there's someone on here who knows the answer to that question...

Stay tuned for more updates and of course pictures of the shavings found in the lower pan...

Thanks for the link...  I search prior to posting, but for some reason I thought it was a oil pump issue.  And yes, when I saw the metal shavings in the lower oil pan, I knew it wasn't going to be good (and expensive).  In fact, even the noise sounded expensive...

I've not yet read through the whole like, but what's interesting is sheepdog mentions the Timing Chain Tensioner may play a role.  I recently changed mine....

I'm not sure if I'll get to it today, but I'll be sure to take some pictures of the internal carnage....  :eek:

Engine + Driveline / Uh Oh....Engine making bad noises...

« on: August 02, 2008, 09:08:15 PM »

So, I just recently finished replacing just about all of the suspension and driveline components on my '91 318iC(read $3-4 K in new parts).  Driving earlier this morning, rather agressively on the revs (not really speeding), after lifting the engine stalled.  I was able to pop start it and continued on.  Later I drove my car back to my house, when about 1/2 mile away, had the same problem, only this time I heard some bad noises coming from the engine.  Got it into my garage and up on jack stands, drained the oil and then removed the lower oil pan...and found a bunch of pieces of metal  (UH OH!).  I'm going to continue to break down the engine, but was curious if anyone has any ideas on what this might be.  Oil Pump?  And, am I wasting time ripping the engine apart?  I'm concern about the metal shavings make their way through to various places within the engine.  What really gets me is that the engine only has 83K on it..

Any comments are appreciated.

Engine + Driveline / Rear Main Problemo

« on: July 17, 2008, 07:42:02 PM »

Two questions:
1)  did you use an OEM BMW Rear Main Seal?  When I rebuilt my M20 I bought one of those top end and bottom end gasket kits (Can't recall the Mfg) and went through two rear seals.  Finally I sourced on from BMW and the seal itself was deeper, making a much better seal

2)  Did you grease the v groove on the seal?  While Bentley and other manuals say to oil the seal, I've had a few BMW mechanics tell me to use grease.

Good Luck!  Hopefully this will save you removing and re-installing the transmission as many times as I did trying to solve my leak issue.
