1980 payloader need some advice on engine

djg12345 · Feb 9, 2018

it?s non turbo and it?s not original motor .... it?s been running great have used it off and on for the 6 months I owned it no more than a hour or 2 at a time ....last night I pushed snow with it for 6hrs or so then it started missing and blowing a little blue / white smoke ....I found he air filter had a lot of snow in it so I blew it out and it ran great again for about 30 mins then started missing and smoking again but this time wasn?t the filter.... after I got it back to my shop I notice oil around where exhaust manifold meets engine block .... any idea the problem ?

Possibly the crankcase vent is blocked.

I would say that your engine is suffering from internal damage on that one hole that is pumping oil white blue smoke is a sign of incomplete fuel burn due to low compression or at best a bad injector . Now as to the low compression it could be caused by a burnt valve , scored cylinder wall , burnt piston ,could be a blowen head gskt. Diesel engines really don't like water getting in them or being choked off from getting air.
