79 300td will not start

I just bought a used 1979 300td Wagon which started up great when I test drove and picked it up. The next morning it would not start but it does crank and lets noticeable smoke out of the tailpipe. The overnight temperature was about 10C, I plugged in the block heater for a few hours before my second attempt and still no luck. The battery has strong charge, the glow light comes on and the glow plugs were just serviced. I know the vales need are in need of an adjustment. Could someone tell me if it is compression related and suggest some trouble shooting and advice??? Thanks.

Severe engine shake at idle

I had some work done recently (installed the Monark injector tips and the radiator hose with the electric heater element in it) as well as some front end work (ball joint, etc.) All of a sudden I'm getting the shake, shake, shake, shake your booty from the engine at idle. It runs great and the shake is more pronounced when cold. Never had it before it went into the shop (bet you never heard that Kent!) So, tips anyone? Engine shocks? TIA Ben

240D dancing oil cap

Kent, Hope all is well. Ran the purge and installed the new Monark injector tips and boy what an improvement! As is always the case, fix one thing and find another... Got your Diesel performance book (with the tips order), went thru the various tests and find a moderately dancing oil cap. Being a noob now hindsight is 20/20 but my question is this - assuming I need to do an overhaul, what is the typical needed parts list, cost for same and "ballpark" labor charge for doing an overhaul. Before I had it shipped from CA I had a Mercedes mechanic replace the timing chain, now the new injector tips and really the car is running fine. So, do I tolerate it and just live with it and wait for the inevitable or be proactive? What actions can I do to reduce blow-by in the interim?
