I'm starting to think I am over my head with my gs. I took my car to midas to fix my exhaust leak and I saw oil near my filter. I changed my pcv valve and had a compression test showing 130-150 psi. So after researching I came to a conclusion my rings are done, I wanted to check with you guys before throwing in the towel and start saving up for a GTE SWAP. any thoughts of what else can it be? My friend thought about putting a breather valve so the oil won't go to the manifold. Thoughts? Conclusions?
