Changed intake manifold gasket. Now loud knock in engine, and antifreeze in oil. Found that Felpro has had gasket problems with this engine.

Good morning,
I have never had issues with Felpro myself.
Can you upload a video of the knock?
Do you have coolant in the oil now or was that the original issue?
