I have a 14 ST3 that I purchased at the beginning of the year. It is FBO and has been so much fun to drive. I've put about 5k miles on it since purchase and noticed oil leaking the other day. I diagnosed it as the rear main seal and took it to my trusted local mechanic. He concurred it was the rear main seal leaking and that the PCV has failed and is what caused the excess pressure which made the rear main seal and oil pan leak.
He has quoted $2,577 to replace the PCV, the rear main seal leak, the oil pan leak and a new clutch kit while he's already got everything apart.
I have already replaced the AC compressor and the motor mounts as one of them failed (~$1,500 for both). I am now trying to decide if it's worthwhile to sink another $2,577 into the car or if there are just going to be more issues that come up and require major repairs. If I get rid of it, I'd most likely be trading in to a dealership and getting $4.5-5k out of it, so I'm still losing $3-3.5k from my $8k purchase price plus another $1.5k in already sunk costs on repairs.
If it were you, would you repair it and hope for the best or cut your losses and dump it on a dealership?
Edit: forgot to add it's got 120k miles.
