It is normal. The O-ring just sits on top of the opening in the oil pan. I went ahead and put some silicone all around the top of the o-ring to prevent any seepage but I think that was a bit unnecessary. I was just tired of all the oil leaks to the point where after I went in to fix everything, I never want to see an oil leak again. :idea:Dipstick bolt removed. During installation, I did not get the dipstick to go all the way in, I can still see the rubber grommet after I tried so hard to push it in. Can somone tell me if this is normal? :facepalm:
