Leakin' Intake Manifold
My '91 is leakin' again after having it replaced about 5 years ago. What is the best gasket to go with and are there any additional procedures/sealents that are recommended. I know this is a common issue with L-98s but, I would like to make sure the job is done with the right materials,etc.
Thanks and Save the Wave!

How is it leaking? Air, oil, coolant? If it is the infamous rear oil leak, you'll have to remove everything. Try re-torqueing the bolts first. I use Felpro gaskets.

If tightening doesn't help and you replace the gasket, put Permatex on the bolts. This will hold them in place and prevent coolant from leaking thru the mounting holes.

You mean a little like this?
I am going through the same thing. LPE built the motor in 1997. Not too bad, it just started piddling recently. It is coming apart soon.

I fixed the intake manifold gaskets 2 years ago.
This was the 2nd time they were done on my car.
The original owner had them done at 15K miles and I did them at 66K miles.
