I'm thinking there was somehow a lack oil getting to it, creating unusual wear or it was just dry and now the oil is just quieting it down. But the noise isn't returning so I really don't know.Can you describe the noise a bit more?
My understanding is that if a bearing goes you'll find copper particles in the filter, which you should cut open. Also, what makes you think it's a wrist pin? In order for a wrist pin to slide out of place, one of the circlips would need to be removed, no?
PS: Heuberger Subaru sells shortblocks for $1645. Pick one up, drop in a CP piston kit yourself, clean your heads, and you're good to go!
I actually removed the one from the passenger side head as I'm using braided stainless line now since I swapped my turbo. I don't know too much about the avcs on this car, I guess I'll do some research. Thanks for the suggestionMight be a long shot but here at the shop we had a 4.6 3v have a similar sound until warmed up and it was the variable cam timing. On the ford had to replace the cam gear phaser. The sti uses the avcs, wonder if that is messing up. Have you ever cleaned the screens in the banjo nut for the oil going to the avcs unit on top of the heads?
I tried to take that attitude as well... Look where I ended up LOL. I hope it turns out to be OK but I would prepare for the worst.If I don't find any metal in the oil filter tonight I'm going to forget that I ever heard this noise
Is it just the two on the passenger side head? I've never taken a close look at the drivers side.It might be a bit of a pain, but I would definitely remove the AVCS screens if you have a chance. If any bits get into the system they'll get caught by the screens, but then that component may suffer oil starvation. (if the screen gets clogged)
:lol: yeah I know. If it happens it happens. Anything can fail at any moment really. I think it will be alright, I'm becoming convinced it was an issue with the AVCSI tried to take that attitude as well... Look where I ended up LOL. I hope it turns out to be OK but I would prepare for the worst.
It sure is! My friend bought it off Neil back in December I think. My friend came back home for thanksgiving (He lives in michigan) and I mentioned the car and how it was for sale. He became pretty interested in it and I ended up going up to NH to test drive it and check it out for him. He bought it without ever seeing it in person lol. It's now being turned into a dedicated rally cross car.That's not the SoloRu behind that wall of snow is it?
