Engine burning oil after rebuild

[Chamberpains]

A measuring cup of oil on the ground in an overnight idle is a lot. I would say something is definitely wrong. It would look something like an oil spot the size of your abdomin on the ground come morning.

That also equates to a gallon of oil every 16 days or so if you idle every night. Which is not horrible if you had a very high mileage engine. But you don't. You said the fool that paid to halfass an overhaul brought in his own head. Which is probably some aftermarket crap or machine shops shitte attempt at being better at designing and machining a head better than a long running multi million $$ ENGINE MANUFACTURER. Well, I'd guess you may have a problem somewhere in there. If MHC did the overhaul, is there any kind of warranty they'll stand behind?

A trip to Mr. Hagg in Griffin, Ga will set you on the right path.
