IP timing issues - replace timing chain ??
1984 Mercedes 300sd Turbo Diesel 350K miles +
I was having some smoke and power issues and I did all the normal things such as new filters, new fuel lines, and finally replaced the injector nozzels which were in terrible shape, badly sooted up and very dirty. The new nozzles are in and at freeway speed she is running great and has excellent power and acceleration.
At idle she is still a little rough and very smokey. I think at freeway speed it still smokes quite a bit also but runs and feels really smooth.
So now I think I have some IP timing issues and I have read one of the more common reason for this in old Mercs is the slight stretching of the timing chain.
My question is this. If I am thinking of replacing the timing chain anyways (as I have recently bought the car with NO history of maintenance and have spent quite some money so far doing other repairs and maintenance) will this fix the IP timing issue, or will I still need to do this after the chain has been replaced.
I think I can fairly easily do the timing chain replacement but from what Ive read adjusting the IP timing is another battle in itself.
