CM 870 High Oil Temp

[2dlb]

Whenever there are higher than normal oil temps combined with lower then normal EGT's that is usually a sign of too much heat being absorbed into the cylinders and not getting out into the exhaust ... it is not a good thing, especially at higher power levels. Can lead to some very bad things like cracked head or pistons, burnt valve, etc. if left unchecked. That is only if this is the actual issue though.

Hi Rawze
Made a tester and pressurized the engine, only leak i can find is air passing rings. wedged the cams and they are good. checked the overhead again, looks good, ran engine and activated solenoids they work properly.I had already reseal the jake wiring plug, so i know its not oil there. I dont recall the oil temps this high prior to reprogramming or an issue with the jakes being rough but hadnt had a heavy load on this prior to parking it at christmas.
Thanks for the help
