Did you have fun with that one? hahhahhah

Stock 240
P30 -Block
E31- Heads
Dual DGVs


Ran the motor with the cover off. With the cover off the noise is not so loud - put the cover on and run it - its just like valve tapping

It is a fast ticking/tapping so I am assuming valve

Narrowed it to the area of valves: 12,11,10 or 9


The problem is, no matter how I adj these four, the noise does not change

I don't get it, you ALWAYS adjust the valves with the cover off.
You should never run it with teh cover off because it will run like crap and be real messy.

Yea, it makes it biggg mess. But finding the tapping is more important. looks like #11 is scored some. If I change the cam, I should use the cam bearings from the head I am taking the cam from correct.
