Going off what john318isau said, also check the fuel pump relay. (common)

Ignition coil make fire......Compression test result = no compression

Chain is okay, tensionner is okay......

Shit, so you tested for compression and you got nothing. This is a strange one. What were your compression test results for each cylinder? Did you check for fuel as well? Have your checked spark plugs for any fouling?

No compression on all cylinder...My mecanical said its impossible, so I got a timing problems.....or something else...

Sparks plug are ok.....

I can tell you what happened. You ignored the original noise which was the old original stamped steel chain guide breaking apart.

Step one, guide breaks apart. Owner ignores noise, big chunk get caught between chain and gear, timing chain slips over teeth. See the teeth marks in the big square piece.

Step two, with the chain now slipped and timing way off you now bend every single intake, or exhaust valve resulting in no compression.

Your engine now requires a full rebuild, anything less and your just cheating yourself. I can help with advise and technical support when your ready to rebuild it.

So, im now thinking of I dont want to put another big lot of money on that. The engine have 340 000 km. Instead, I want to buy another less mileage engine. If it's cost me 1500-2000$, I will prefere that. And the car will be more reliable.

So, did im obligated to put another m42b18 engine or I can put a m44? What's the difference? It's because im not able to find another low mileage m42......or I can check at metricmecanic, but fully rebuilt engine cost 7000$..........

Do you have place where I can check for m42 or m44? Im living in quebec, canada, i can't import engine from germany

Thanks for car-part, I will check. Anybody have an idea about fitting an m44 instead of an m42

Did you end up removing the timing covers and inspecting the destruction?

pifane · « **Reply #24 on:** July 14, 2008, 10:59:58 AM »

The fact is that the engine have 340 000 km and I just dont want to open it! It's because I dont have time to do this,Im a business owner and im working everyday,and If I pay someone to do this, he will told me that my engine is to rebuilt or something, and that will cost me 200$ just to know that....and I already know its an old engine at end of life....BUT! Im looking for a low mileage M42, and if I find one (I have no choice to find one, I want to keep my old school E30), at this moment I will open the old one to see what happening.

So, for the moment, Im driving a E36 with climate control still working, and I really enjoy it on july

Hi all!

I think I have find one. That have been very hard. I find one with 192 000 K (120 000) for 1000$ + 300$ shipping.

1300$. Now im just asking if its better to me, once the new old one arrived, to replace : chain guide, timing chain, tensionner and water pump ?

I think its what I have to do to have a reliable engine....no? What other thing I must change before swap on the other one?

(I want to have somekind of peace....)

I would give the engine a major service - meaning replace air, fuel & oil filters. Replace oil and spark plugs as well.

I would replace the following
- valve cover gasket and spark plug seals
- timing chain
- cam sprockets
- crank sprocket
- idler sprocket
- all 4 guides
- tensioner piston
- front crank seal
- thermostat
- water pump
- all 3 drive belts if worn
- relevant gaskets and gasket sealer (use sealer on timing covers not paper gaskets - they're crap)

The parts above is what I replaced when I did my timing chain.

pifane · « **Reply #27 on:** July 23, 2008, 03:35:42 PM »

Okay. After calculating what I have to replace, Im not sure anymore....

New old engine with 192 000 KM:
-If the engine have not running since 3 years, that will be pain.....
-1300$ right to my door and 500$ parts (maybe more) and 5-600$ labour...
-Job will be do by a good mecanical but.....im not sure he know everything about bmw....

My old engine:

Engine Block is still good, new water pump, new thermostat...

Finally, im not sure about what to do here...lol....Tomorrow im going to a specialised imported car shop and the owner look to be very nice with bmw (He repair and rebuilt bmw, mercedes, porsche, maserrati car since 25 years)

He said to my brother of a well rebuilt bmw engine can be still good to another 350 000 KM with no trouble.....and he can make a warranty on that!

I will keep you informed my friends!

the second mechanic is right. if the engine is rebuilt right, its as good as a new engine.

I very hate the fact I don't own a garage....I have to pay the big price to rebuilt my engine. It will cost me 2500-3000$. 50% of the price is for labbour.

If everything alright, I will have my car in 3 week....."I miss you getrag 265
