History note-this is a new to me auction buy, got for cheap, overhaul really tight machine, even after inspected by IH mehcanic, Mechanic said even if the combine was shot, the engine is worth what the price was. No idea how long it sat prior to the auction, no idea what grade oil was used in it, I put in 15-40 Rotella. Issue. Started spewing oil out of Crank vent tube. About 1 gallon in 70 minutes.
Info. on engine
Starts great, other than cold start of really working hard does not smoke like she is burning oil. Replaced vent breather element
Has valve cover vent, not the side of block.
Engine runs great, plenty of power.
Oil pressure>not sure on #'s, will be buying a mechanical gauge to test, BUT, when first started on a 65 degree day, it pegs the gauge, and will stay there when warmed up and running full throttle. At idle engine at operating temp(hot), gauge still stays over 1/2 of the range, closer to 2/3. From idle to 1/2 throttle i only have little puffs of smoke. No oil dripping from vent tube, bring up to fulll rpm and the oil starts flowing out of vent tube. Is it possible oil pressure relief valve is stuck? Is this only caused by engine wear Ie worn rings, walls? Just seems like to tight and great running of an engine to have blowby so bad it pees out engine oil, yet has no other symptoms of a worn out engine? Can you all give me some advice? Bad valve guides? Want to cover all the bases before I bring it to some one for a sleeve and piston overhaul.
