I am going to be replacing the timing chain and chain tensioner on my 1986 2.3 8v. I have done some research on this and have a pretty good idea on how to do it. I just have 2 questions.
1. Any tips/suggestions/advice from those who have done it themselves
2. Should I be replacing all the timing chain rails with the chain or am i ok leaving those in.
The reason i ask #2 is that to just change the chain/tensioner you don't have to remove the front of the car (radiator etc.) and it seems to be a much easier job. However, do/should the rails be changed? The reason I am changing the chain in the first place is a. 150k + miles and b. the car sounds like a diesel (chain slap i think).
TIA for your help!
I recently purchased an 86' 190E 2.0 ltr and me and my fiance found that the timing chain seems to make a bit of noise, especially on start up but is there constantly and can occasionally hear it while driving.. We went to a mechanic to ask about it and he said that they should never have to be replaced? He says that he used to own a 190E himself, so he thinks he knows a bit about them. Can someone clear this up for me, ive heard a few different things, ive read that they need replacing every 100,000 kms?
Can someone plz help? (sorry for hijackin this thread)
A loose timing chain and/or failed chain tensioner is a very specific sound. A metallic rattle at start up from the front of the engine until the oil pressure builds up, then it goes away.

Don't cheap out, change the rails. It's also the appropriate time to consider the oil pump since you're in the neighborhood.
Correct me if i'm wrong, but that involves taking the entire front of the car off (as stated above) to replace the 2 rails. Do these rails wear out, or is it likely that they are worn and need replacement? I don't know if i want to spend the extra hours to replace these parts if they don't need to be, thats the only reason i ask. The rails are inexpensive as is the timing cover gasket.
There is a huge difference in just replacing the chain and tensioner compared to replacing all the rails etc.
One of the problems with the early single chain M102 engines was that the intermediate gear that drives the distributor wears and eventualy looses it's teeth.
This can only be repalced by removing the front cover.
You can see the gear with the rocker cover off. Look at how thin the tips of teeth on the gear are, if they are still thick, it's OK.

ok, so what your saying is that you can only replace that gear with the timing cover off. What is the name of that gear? How hard is it to remove the timing cover to replace the timing chain guide rails? If thats the way i go, does it make swaping the chain easier?
