Have been dealing with an oil leak on my wifes 1994 z28 for about 3 months now.We bought the car used and have been upgrading things little by little.Okay heres the problem when you put the car on the lift you can see the leak coming from behind the waterpump/opti.I replaced the crank seal and the rear main seal along with the seals on the tranny just to stop the other little leaks.I can't stand oil leaks!!!Any way we pulled the water pump and the opti and everything looked dry.I don't know what else to do can somebody lend a hand or some advice,I would realllllllyyy appreciate it.

 

check where the intake comes in contact with the block, I know you said it looked dry but fresh oil is hard to notice until it travels downward and picks up dirt and grime, I'd also look at the seal on the water pump shaft, and the seal on the shaft that drives the opti. also could it be your power steering pump slinging its fluid?

 

Yeah everything looked okay but I guess I will tear it back down this weekend and double check everything thanks for the tips any other other advice will be appreciated.

 

I did the intake on my 94 all was dry after that, but I did the intake on my 96 sunday and still have a leak on the front like you. I noticed the crank position sensor may be leaking but please post what you find so I may figure mine out and I will do the same. Allen

 

No problem,i'm taking my wifes car to a guy here in town that works on camaro's and hopefully he can fix it.

 

well the intake helped the leak in the back I still have one in the front. I am going to redoe the water pump next and a crank position sensor, any luck on yours yet?

 

My friend is going to work on it this weekend,hopefully he fixes it,he mainly works on ls1 engines but knows the lt1s,I will let you know what he finds and good luck on yours,if he cant fix it I think I might sell it and get an ls1 car(lol).
