Default '94 SSE Series 1 Intake Manifold Oil Leak

I just had my intake manifold resurface and replaned less than a month ago and it is already leaking on the drivers side. It looks like one of the two long rubber gaskets (the driver side) is leaking. I don't know what this guy did, but it is leaking. I'm bringing it in on monday to have him redo his job.

Anything I should tell him so that it doesn't leak again?

Default Talked to the Mechanic

I talked to the mechanic who is going to be working on the car on Monday. He told me he doesn't use the two long rubber gaskets on either end of the manifold but simply fills it with silicone.

Is this a good Idea?

Default Rubber Gaskets

The last mechanic used a rubber gasket.

Did he use just the gaskets and no Permatex? Either way, he did it wrong the first time cause it leaks already.

Yeah, use the real gaskets, those ones like that can be slipped in without removing the piece the gasket fits between.

No sealant or permatex at all. The new gaskets are improved. Buy them from GM. The old gaskets are prone to oil leakage (spatter, not a pressure leak) at the joint where the heads, lower intake, and block all meet. This is normal after 100k miles or so, but should be repaired with the improved gasket set from GM ONLY.

Here'* a pic of what they look on my neighbor'* L27 (who had the same problem):

You're looking at the 2 blue gaskets.
