Tapping Lifters
Posted: Sat Nov 20, 2004 9:16 am
In relation to this post I discovered I now have very quietly tapping lifters. My oil is fresh, full, and the proper weight (actually a bit heavy).
I have absolutely no idea why my lifters are tapping. I've been a rabid anal freak when it comes to oil changes, I've never had the same oil in that engine for more than 4000 miles. When I pulled my valve covers a couple years ago, it was hard to tell the engine had even been used, the valvetrain was so clean. The car only has 138k on it, and it seems like some of you have 160k-180k on your engines with no such problems.
I guess I have two options at this point:
1) Pull the oil pump, and might as well rebuild it (new set of rotors and reseal). It's possible just the backing plate is loose, but if I have it off, I might as well maintenance it.
2) Actually pull the rocker arms and replace the lifters. This will be expensive I know, but I refuse to half-ass things and dump mystery oil additives in my engine to shut it up.
This is extremely frustrating and deems the future of this car uncertain, as it's already got waaaay too much wrong with it already. I've already got two other Subarus in mind that could replace this one, and I'm not afraid to just eat the cost of what I've put into this car and just start over.
