Hello, my girlfriend recently acquired what we thought was a good 300TD Wagon. The car started right up in cold weather and had good power despite that it isn't even a turbo engine. After driving a couple of hundred miles I noticed that the oil was leaking profusely. We brought it to a mechanic who diagnosed it without a compression test to have a worn out engine with blow by. We then brought it to another mechanic who said the same. It now wont start at all. Is it possible for the engine to deteriorate that quickly? Before she bought it, it had had a valve job and new timing chain. I recently re-adjusted the valves, most of them were very tight but following the adjustment no change is apparent. When trying to start it, it will not even hint at trying to start. Before it quit, it didnt have much of a problem starting but was starting to run rougher. I also recently did a compression test on two cylinders which were both around 200 psi. after 8 cranks. This was done on a cold engine as it wont start. the other cylinders were in a position so that i needed another adapter to reach and so I am planning to return and test the others soon (the car is 2 hours away at my girlfriend's moms house) but 200 isnt good anyhow. I am just wondering what can be done as i would like to get her car back on the road. New rings? could the timing chain have slipped due to an old tensioner? Also, the odometer only works intermittently but registers 167000.

Thanks

Nick
