have c15 just rebuilt oil coming out of all 6 exhaust ports will the rings seat in time or should i tear down an replace

Hi. Thanks for using JA! I will try and help you out.


They should seat after the engine has been out under a good load. I would not go back into the engine until the engine is loaded.


Has it been loaded yet?


Also, did you use Cat parts or aftermarket parts?

aftermarket rebuild kit ipd or mc b brother cant remember. motor has only run for about 30 mins in shop shut it off when seen oil coming out of exhaust


I see. Thanks for the information.


I was thinking it was an aftermarket kit. I have had two customers have the same problem. One of them put the engine on the dyno and loaded it and th oil stopped. The other customer pulled a loaded trailer and the oil did not stop. He had to go back in the engine. I would try and load the engine to see if the problem stops.
