I recently bought a 1998 Impreza 2.5 RS, and the day after I bought it it started to make some engine noise. The noise sounded similar to a rod knocking, but a bit more subdued. I took it to the dealer, and they said it had too much oil pressure and it was causing valvetrain noise. They told me that it should be around 40-60 PSI, and it was reading 140 PSI. They flushed the engine out, and it is better, but I have heard the sound once or twice since.

Does this sound odd? I am a bit worried about this.

Maybe you should get a leak-down test done. Too much oil pressure could damage seals and gaskets, depending on how long it was running too much pressure.

Hopefully, it wasn't running that much pressure long. I'll have to get it tested soon, thanks. So this isn't an unusual problem then?
