    Does anyone know how to get to the oil pressure relief valve on the 5vz? My oil pressure gauge wasn't working so I decided to hook a gauge up to the engine and it reads close to 90!!! I need to check to see if the relief valve has seized. Enginr has 300k hoping its not blocked with sludge. Plan on taking a look inside soon.

    Looks like you would have to drop the oil pan to access it.
