Had a truck in the shop last year,head gasket leaking,replaced head gasket, cyl head overhauled,run engine, burning oil,removed cylinder head and pan installed new rings, run engine, it smoked again, got cylinder head checked again, installed hastings rings, not to dad,sent back to the customer, truck came back in,oil leaks, perfect ill pull the engine, and rebore new pistons rings and head checked again, guess what burning oil any ideas. used two different machine shops.
Showing items 1 - 4 of 4 results.
Less than 40000hrs on the unit,two cylinders oiled up, head back off and at the machine shop. No oil in lines from breather to intake manifold,50hours putt on engine last year.
Are all the spark plugs oil fouled or just 1 or 2 cyls? If all fouled I would suspect a faulty breather system or baffle assy in valve cover.
Try running with all breather lines disconnected & see if smoking gets better/worse
I tried to use cheaper parts, caused me grief. I try to use good quality or OEM parts when it comes to engine overhaul. How many hours on the engine??? Did you flush and test rad,water pump, thermostat ect.. ?? 4g33 or 4g63
