Hey everyone,

I have a 350 TBI in my 1994 C1500, i have a pretty big oil leak on top of my intake manifold below the distributor, im guessing either the OPS is bad or the distributor O-ring/Gasket. My question is, does the distributor on this engine have a gasket between the Manifold and the Distributor, or does it only have an o-ring in the distributor??

Regards,
Jeffrey

More than likely the intake needs to be resealed. The front and rear of it is sealed with black RVT.

Can it be the intake gasket if there is oil on top of the manifold, around the dizzy? The entire shaft of the dizzy is soaked with oil, i was also thinking maybe the brass elbow fitting from the OPS. But if it is the intake gasket, will there be oil on top of the manifold??

I replaced my distributor a couple of years ago. I'm almost positive there was a paper gasket that fit between the distributor flange and a the counter sunk machined surface on the intake. In addition to the intake seal to the block as mentioned above, there's also an oil pressure sending unit back there. It could be that this unit is leaking oil and dropping onto the intake manifold. Normally they "hang" in a position that this couldn't happen but perhaps the pipe has been twisted in such a way that it hangs over the intake manifold. It's a long shot but maybe. I'd clean it all up and put some dye in the oil and with an ultraviolet light and glasses find the leak. Napa has a kit for around 20 bucks.

there is a gasket between the distributor and the manifold. absolutely necessary to prevent a leak
