c5 corvette z06
Ok guys, i pulled in my house one night and noticed a burnt oil smell. Popped the hood and saw oil spewing from intake manifold gasket, so the next day i pulled everything off replaced the gaskets and go to start her up and BAM
A knocking noise, so i had a mechanic buddy come over and said i didnt bolt down the manifold correctly so we took it all off again and did it all over, cleaned everything up and bolt it down coreectly and its still knocking.
So today, we decide to take off the valve covers to check the rods, springs, rockers just everything visual. Everything was good rods were straight. Had some extra coil packs lying around and tried those on just for a shot too, and still it is knocking.
It has never knocked before. And doesnt have crazy mods, Just intake and a tune. So i have no idea what is happening or going on. Dont see why something this bad could come from replacing gaskets, and no i didnt drop anything in the motor
IF anyone can help, i would greatly appreciate it!!
