I have 3800 sII sc from a 99 grand prix in a 87 Fiero GT 3.25 sc pully, all egr removed valve cover vented was told rebuilt 2000 miles ago. Have put 3 new seals and new harmonic balancer cleaned entire front of engine and painted lite gray also put dye in oil and can not get seal to stop leaking. Using royal purple synthetic oil. It is coming out of seal/balancer not out of cover to seal. If you have had any problems like this please respond!!!! Leaks at mid to higher rpm let run for 45 min with new seal and no leak till run up rpm,s.
