#2 cyl. Wtf. Not even running it hard at all.
Thats what im trying to figure out.What caused that?
if its been running for 15k since the work i dont think thats it. i have seen (only once) in the 6.0l on a compleatly stock engine a badly worn cam lobe cause valve to piston contact. but i dont know for sure. best of luck on your hunt.
I'm not trying to argue with you guys at all, but I fail to see how a flat cam or collapsed lifter could cause valve to piston contact. If anything, either of those would keep the valve from opening all the way/at all.I would say that it is either a worn camshaft or a collapsed lifter.
thats one of the issues right there. take a couple thousands off the heads,then add those pos gaskets. bo gaskets are 10 thou thinner than oem motorcraft gaskets. do the math....Trying to figure out how much elites machine shop took off the heads when it was there.
"a little" isnt a good measurement imo.
Its been running for 15k since the headgaskets were done. Done plenty of hard towing and hard driving with the stock program.
03 truck with a 05 motor
It has h11 studs, black onix headgaskets, powermax, 54v ficm, 190cc hybrids 8 hole, reg return system, fs2500, snow performance w/m, coolant filter, full egr/ cooler delete, 3.5"dp, 5" full, afe, full gauges, etc....
lots of reasons it could have been one hole. you would think so. put weak valve springs,and,or high drive pressure in the mix,on a engine that already flirting with piston to valve clearance issues,due to machining and thinner hgs,and lots of carnage can result.Wouldn't you have seen the damage on more than one pair of pushrods?
Crap. Anyone know the compressed thickness on both oem and the onix?thats one of the issues right there. take a couple thousands off the heads,then add those pos gaskets. bo gaskets are 10 thou thinner than oem motorcraft gaskets. do the math....
i have the specs somewhere here that you want. point blank. motorcraft gaskets!!! that should be the only gasket you use.. ill see if i can find the info you want.Crap. Anyone know the compressed thickness on both oem and the onix?
Are there any other headgasket makers out of curiosity?
