Thread: Engine spraying oil at high RPM

Tweet

Hi Everyone,

this is my first post to this site. I have read other threads about SBC spraying oil but so far i havent got the answer for my specific problem.

So what I have is a marine 383 stroker. This was a brand new engine (reman) from the factory. it ran very smooth for the first couple hours of use idling and up to 3500 RPM. once pushed to higher RPMs i got a warning sound that I had low oil pressure. I opened the hatch and the entire engine was covered in oil. Also since this time it no longer sounds smooth. it sounds like i burned up a ring or has piston slap.

the engine only looses oil when at full throttle. I have found oil in the intake.

Any thoughts on what this could be? i have attached the spec sheet for the motor as well
