Bought this flywheel new last summer and have put less than 1000 miles on it.
I don't remember seeing these marks when I installed it. What would cause this? I don't see any marks on the case. Also, besides the rear main seal leaking, it looks like I'm getting some leaking from the gallery plugs (I think that's what these are called). They appear to be in tight. Is it advisable to remove them and put some sort of sealant on them? |

I think a screw got in there....probably made those marks the first time the engine turned over and tore the lip of the seal as well...rattled around a bit making pocks further out on the flywheel before being ejected.... |

Hmmm the seal was perfectly fine. No marks. I'm 100% sure there wasn't a screw dropped in there. I suppose there could have been a small piece of metal debris though? I really want to verify all is good before I put everything back together. Do I need to worry about resurfacing the flywheel where it's marked up? |

Something that catches my eye is that the entire shoulder is polished clean as if it's been rubbing on the face of the seal. That doesn't look right to me....like the seal isn't seated in far enough. There should be some clearance there, right? In which case, if the flywheel is hitting the seal face, it's giving you a false reading on the endplay of the crank....the thrust face of the bearing is what it's got to be limited by. Repeat your endplay measurement without the seal in place first....then install the seal far in enough such that the endplay doesn't change & you'll have it nailed.
As long as the surface that the seal lip rides on is smooth, no reason to do anything to it....mount new seal & go! |
