Re: Valve Tulipping
Detonation causes tuliped intake valves.....
It also can show up as top ring land excessive wear and obvious damage to the pistons above the top ring.
Bad gas, to much timing.....some sort of timing malfunction during a run that allows timing to advance with RPM....
I had a digital box once that advanced the timing to over 70 degrees once the engine started.....Holley Annihilator.......!!! Took me 3 tries to get one of those boxes that worked.....
