On Leaky Oil Pans and Intake Manifolds
Before I pulled this engine I knew I had some serious oil leaks. I was getting drips on the garage floor and the whole bottom of the car was coated with oil. It was coming from the front of the engine but I could also see some coming out of the weep hole on the transmission. I figured it was the front crank seal and the rear seal. The more I thought about it, the more I started to doubt that such epic leakage could come from just those seals, especially since the front seal was replaced about 35k miles ago and the rear about 45k ago. On a hunch last night I poured 4 quarts of oil into the engine as it sits on the stand. Within minutes I could see it starting to seep out - from the oil pan on both the front and rear of the engine! You don't hear about oil pan leaks on these cars very much, but it looks like I'll be pulling the oil pan off and resealing it this weekend.
