Once again the lovely LT1 is dripping oil, you would think this would stop after all the fixes i've done to it. Its a 96' Z28, I just did the oil pan gasket in May, had the rear main replaced a few years ago and NOW its leaking from the front of the engine. After doing a little research I'm under the impression that it could be the seal on the crank that spins the water pump...haven't changed that yet and did take the water pump off to replace the gaskets. O and there is a coolant leak at the front AGAIN, guessing the gaskets didn't seat right. Either way anyone had these problems???????? Suggestions???

 

I'd say check your front cover first, then take a look at the seals that you mentioned. I'm suprised that your rear main seal was actually bad, all LT1's leak from the back of the intake manifold unless it's been fixed correctly.
