HPOP oil leak
Having a problem with oil leaking from under the HPOP on my 95 Club Wagon with PSD. Bought the o-ring kit from a local dealer and started to check out where the oil is leaking from. Seems that my o-rings were not the problem. The lines coming from the HPOP to the heads were dry. Since the PSD is in a van, in order to find where the oil is leaking from I had to go in from the back of the motor. (Through the doghouse area.) Ater tearing everything from the top of the motor to access the HPOP area I could see the oil was coming out from under the pump. I removed the pump and inspected it. At first it looked like there might be a crack in the pump, but I buffed and polished the webbing area and it was not cracked. The mating surface between the pump and the front cover looked fine.
Now I need to re-install the pump and figure out where the oil was leaking from. The seal in there looks like RTV. I need to know if the seal has been a problem on these engines. I would also like to know if anybody has the torque specs on the gear bolt for the HPOP.
Any feedback would be greatly appreciated. Really want my van back in running order. Soon....
