Replacing intake manifold...

[COBALT]

I'm replacing my intake manifold with one that's exactly the same. Questions:

1. How should I clean the lifter valley once I get the old one off?

2. I thought there was a gasket for the distributor? A little round one??? Duh...

3. I'm thinking I'll dab some RTV on the corners of the gaskets to keep them in place. What about around the bolt holes to keep oil from seeping up around the bolts?

4. The little gasket strips that go in the front and back of the manifold...do I RTV those? Sounds like I should (at least to keep them in place).

5. Lets see, if I pull that vaccuum line from the intake to the brake booster do I introduce air into the brake lines? It wants to "hiss" when I start to pull it. I'll have to bleed the brakes, right?

Just some concerns. I want this to go as smoooooth as possible my first time around. I want exactly ZERO oil leak vs. the seepage I have now.
