Oil blowback
Car has- LT's, Fast 90/90, cam, pushrods replaced less than 5000 miles ago when we did the cam swap.
Any idea what could be going on? I'm pretty sure these two are connected, and the rapping doesn't sound good. I need to get down and hear the noise myself, but I have no time to do that until this coming weekend so I'm hoping I can get some ideas between now and then.
It's a 99 z28 with 66xxx on the clock.
