This is my first 2.7 to rebuild. Could someone help with a few things. This one the rob bearings on # 6 went down. I don't see anything that could have cause this at all. No sulge at all. Oil and engine look great inside. Rod was fixing to fail. I am replacing it though. " My Question is how do you prime the oil in this engine". to make sure everything oils like it should. Is there any precaustions that I should take. Only want to do this engine one time. Don't want to inhereit it. I have seen a lot on the web about these engines. I don't see a spell check so sorry.
