Thanks, I will look for the most expensive Felpro intake gasket.

That intake gasket separates coolant and oil from air/fuel. I would first replace the intake gasket and go from there.

If your not satisfied after that, do a compression test on all cylinders (for comparative figures) and the coolant test strips.

The gaskets are a bad design, Dexcool is not to blame for that.

Fel-Pro MS98000T are gaskets you want, I agree with Mykk....Sounds like intake gaskets.

Before tossing the gaskets I gave them a brief inspection.
The rubber like seals had little elasticity and broke very easy; not sure what to blame but pretty sure they would be more robust and elastic when new.

The plastic support for the rubbery seals easily broke also.
