7.3L Power Stroke Engine and DrivetrainDiscussion of the 7.3L Power Stroke diesel engine and drivetrain in the 1999-Up Super Duty trucks and Excursions. No gas engine discussion allowed except on transmissions and drivetrain that pertain to all models. Please confine discussion of topics in this forum to those items that are specific to the 7.3L Power Stroke engine.
It is NOT a new engine-quite the opposite, its got 202,000 miles on it.....
does the fact that its bending BOTH valves eliminate a blown headgasket? I can see if the valves are blowing open from boost bending intakes, and if the exhaust was doing it I could see a headgasket leak, but I CAN'T see either of those bending/breaking BOTH intake and exhaust? The last time this happened after flogging it at high RPM/BOOST for a couple miles on the open highway errr racetrack.....She hit 139 before it let go.....

Sorry, I thought I remember you posting about putting in a newly-built engine. So many posts on here, it's tough to keep track of who did what! Especially with my feeble memory! Did you very recently add some new mod?

compression check tomorrow after I get all the pushrods/rocker arms put back in.........will keep you posted
BUT would a bad headgasket cause intake pushrods to bend? there would be NO other indication of this?

I'm gonna say you tightened them too tight and squooshed the heads smaller, and now the valve stems are too long. [img]/ubbthreads/images/graemlins/wink.gif[/img] [img]/ubbthreads/images/graemlins/biggrin.gif[/img]
I really don't have a clue why it would be bending pushrods. Something is obviously interfering.
lol-that would be funny wouldn't it? dunno if its possible.....but if it is, its my luck that it WOULD happen.

new pushrods and rocker arms, she is up and running (pretty well actually) with a light tick when cold (goes away after 45 seconds or so) and good power. Im assuming the tick is a pushrod I missed being SLIGHTLY bent, but.....this still doesnt explain WHAT is causing this. Mike
