ok heres the beef, i got a b16 milled .080 w/ ctr pistons ok now when the car idles there is alot of valve noise but it seems ok. now when i turn on ANYthing electrical such as fan, break lights, or radio, the rpm's drop from 1000 (thats what i normally idle all the time) to about 950ish and the engine begins to ping. not a loud ping but its noticiable. the more electrical stuff that is on the more it pings. whats the deal with this, any insights?? thx in advance, also one more question why do some people post only "bump" after some replys, does that move the thread to the top of the list again?

 

bump for someone to help me out!

 

milled .080!! the piston is probably hitting the head!

 

bump for someone elses insight, its .080 mm not inch.
