Okay, so I'm about at my wits end here. I have an LT1 that was rebuilt by a machine shop and abandoned. Good deal for me to pick up, or so I thought. And now on to the the annoyance that has been plaguing me. The distributor keeps getting filled with oil causing the car not to start. I've changed the seals 3 times in the timing cover, but it keeps happening. It goes together and everything looks fine. Car runs fantastic for a week or so and then it doesn't start again. If I pop the cap off, oil comes out, clean it up and the car runs great again. As you can imagine though, this has become a major annoyance. So has anyone else ran into this problem? If you have, I'm dying to hear the solution...

Not to say it is common but since it is a cam
Driven water pump have you checked the seals on the water pump?

Is there any more car info other than "I have an LT1"? Is your PCV system working? What opti are you using? How old is it? Have you tried another one?

Water pump drive and seals are new. Pcv system is functioning properly. Timing cover is correct for a 94 with the spline driven distributor. All seals in cover have been replaced.

Almost forgot, distributor is a brand new gm unit with 25 miles on it. Changed form MSD unit. This is in a 94 Z28 btw

pull the vacuum and fresh air hose off of the opti and see what happens

It is not going to have any, is it? It's a 94.

OP, you need to see if you are possibly getting any excess crankcase pressure. See if you are getting any puffing out of your oil fill. I can't really imagine this type of scenario. It's pretty strange.

Shbox is right. These are not on here. I will check into the excessive crankcase pressure. Like I said, everything is new, but you never know. It's a real wth type of situation. I just don't understand how oil could get into the distributor cap like this... With new rings and such in the block crankcase pressure shouldn't be an issue though.
