[Vwdiesel] Big Problems with Engine (I think)

[Jason and Lori Stoffer]

Hello all.  Thank you for the suggestions so far.  I will attempt to tighten the head bolts and see if that helps.  I realize that I didn't give very specific info on the incident as it happened this fall.  In response to some of your questions-
 
I don't think it is a gelling issue because it was in the 40's or so when the power loss occurred. 
 
The oil cap seemed to have come off by itself. Blown off? It is an aftermarket cap.  
 
Remember it will fire and run for a few seconds before dying again so I don't think the chain may have slipped. 
 
As for some more information.  The engine is a golf diesel I believe and it had two exhaust outlets, one of which was just covered with a plate and the other is serving as the main exhaust to the muffler and tail pipe.  The cover blew off a while back and rigged up something temporary. There is still exhaust leak into the engine compartment which a think cycles back into the air intake (my filter is always jet black) and there is oil puddling in the air intake behind the filter.  Could this have anything to do with the my engine problems? I will try to heat up the garage and tinker this week.... Will let you know what I find.   
 
Thanks, 
Jason
