L36 maniflod clea up and LIM gasket choice

[biglion]

whats the best way to clean off all the oil off the manifold

also which LIM gaskets are better to use i see good reviews on the felpro brand and i heard the GM wasnt as good

 

[Fivefingerdeathpunch]

Felpro aluminum gaskets are the best.

And brake cleaner or soak it in some simple green/purple power to clean the intake manifold.

ok thanks i look them up :th_thumb-up:

Since you have the L36 manifold.. have you considered plugging the coolant ports or replacing the manifold? It's a common failure point.

I just did all this recently, I think it's very worth taking the extra step to plug the holes in the LIM... I got all the necessary parts at O'Riellys

Mine are plugged too thanks to Billboost. Combined with aluminum coolant elbows, aluminum LIM gaskets, and the plugged LIM, I don't have anything to ever worry about again with this motor.

no i haven't considerate it so im not sure what that is so is that a modification or some sort but im replacing the intake plenum

You had asked about cleaning the manifold and I thought you might be cleaning the upper intake manifold. If that's the case, I'd suggest plugging the ports suggested in that thread, because the EGR runs between two coolant ports in the upper manifold and over time the heat will crack the manifold and allow the coolant to dump into your engine.

That link.. if you haven't already read it, should be a must read for anyone with an L36. It shows you how and why you could have a failure.
