changing oil pan gasket

supragirl1983 · 12-10-2017, 04:17 AM

Thank you for responding..I have fixed the pan gasket to only find out that my main front seal has gone bad possibly? It appears to be leaking oil from that place ? I dont know where else it could be coming from? I know my head gasket hasn't gone bad ..I have no signs or symptoms to make me lean towards this...however I am investigating how hard it would be to replace the main front seal?! It looks timw consuming though and I believe at this point the motor may need to come up to get to this...😞 my baby is down yet again ...😱

Not the end of the world infact a fairly easy fix if you have any experience with timing belts and pulling out old seals.
I would recommend purchasing a whole timing belt kit that comes with front seal and camshaft seals.
If you don't have the money to purchase the entire kit simply buy the front main seal it requires if memory serves to have the timing belt removed and the crank shaft snout exposed, all can be done with the engine inside the car and radiator and ac cooler removed.
personally I put thread locker on my harmonic balancer too. If you have any question about the procedure I am happy to help

If you are not mechanicaaly inclined, just go to a reputable shop to have the seals replaced.
