Guys I am new to TractorByNet and this is my first post. I have a Dresser TD7E. I had the engine completely rebuilt will all new parts. It cranks and runs great, but after it runs a while it starts blowing oil out the top of the engine. Someone told a friend of mine that the lifter rod needed adjusted. Can anyone explain how to do it? Or suggest other things to check? Could it be the oil pump putting out to much? I'm at a loss. Thank you for any help you can provide.
