Timing chain
Has anyone ever been able to retrieve a broken timing chain and then install new chain from access under the valve cover w/o front engine disassembly? After a hard stop at ignition and subsequent starter replacement I realized that my cam is not moving, so chain is maybe laying in the bottom of the oil pan? 240D

Its an interference engine. You likely are in for at least couple of valves. There is no front cover for the engine. Probably when you remove the cylinder head you will be able to fish the chain out. Unfortunately there is no easy way. The total job is not that hard in my opinion. Find a MB engine manual.

I am thinking the same thing, snag the old chain and then magnetically retrieve and match every single remaining part out of the oil pan. I am wondering if I should just do the whole head at the same time, do you think that is a good idea at 155k miles?
Just can't believe that this happened at 155k, I am a maintenance fanatic and the engine ran perfectly up to this point, absolutely no indications of any problems, just thought I would be doing the head at 450k. Be forewarned 240 D's: check your tensioner, do it now!! Thanks Chris |

I would say check your vacuum pump. It is probably the cause. By the way I do have a 240D with clutch and transmission looking for a new home, just saying.
