Ok in the last 6 weeks ive fixed 4 oil leaks back to back. I fix it and within a week theres a new leak. First the OMP started leaking fixed that and the oil filter pedestal started leaking, fixed that and the rear main seal started leaking, fixed that and the oil pan gasket started leaking. With all the leaks they only leak when the engine is being rev'ed never at idle. At first I though the oil pressure was just blowing the gaskets since it is a old motor but with them happening back to back and only under load i figure it has to be something else as well as the oil pan gasket should pickup any pressure from the oil pump under load. Do our cars have a pcv valve that could be clogged or is there anything else it maybe. According to the stock oil pressure gauge the pressure is fine its not to high. The car doesnt burn any excess oil and has never been ran with synthetic to my knowledge, The engine and turbo both have about 125k miles on them. Doe anyone have any idea what might be causing the seals to go. I can accept the fact that there just old but I dont want to keep replacing gaskets and find out its something else.

Thanks
