Piston hitting valves?
Hi All
yesterday i changed my intake cam timing on brian crower stage 3's from +2 to +3. Now it runs fine up till about 5000rpm where there seems to be some tapping sound. As soon as i hear the sound i change gears and it stops.
Could the Valves now be hitting the pistons @ 5000rpm?
Im running stock 9.5:1 pistons, it was fine at +2 even at 8000rpm.
Im running aftermarket ecu with advanced timing maps, could it now be pinging?
