Well, I just finished replacing a head on my '90 Grand Am, and went to fire it up.
You guessed it, just as post-rebuild, I recieved a wicked knock in greeting.
Since the head was replaced, the only think that I can come up with is that a lifter went.
The knocking is irregular: frequent, but irregular.
What do you guys think, could it be the lifters?
Another thing, how do i check the oil pressure? This is one thing i'ver heard should be checked.
Doh, forgot to add, its a 2.3 LO Quad4.
