What style gasket does the lsj use were the intake manifold meets the head? is it reusable if I were to remove the manifold? is this gasket the same on all ecotecs? any info will be a great help.
thanks

 

This is the gasket that you will want to be using and luckily the price just dropped recently.

If you have an 05/06 you will want to upgrade to this "new" upgraded intake manifold gasket that will help the issue of the dipstick popping out. I highly recommend replacing your intake manifold gasket if you are taking off the intake manifold.

 

It's a single layer metal gasket, totally re-usable unless damaged, but as Zach said, if you have the early style, you should buy a new one and get the upgraded one. Also, if it's been off a couple times it tends to flatten out and may not seal as well as it should, although I never personally had a problem in the many times taking manifolds off. It's not expensive though.

 

when I went from the stage two pulley to a 2.9 like a year ago, I started having this issue, replaced the gasket with the updated design, problem solved.
