First Time I Go WOT in 6 months - Bent a Pushrod? Just finished doing the 500 mile break in on my rebuilt T56. Picked up a buddy and finally got to make some WOT passes. On the 2nd run, flashing SES, slightly noticeable power loss, car feels weak and surges under 1500 rpms, sounds like a combination of an exhaust leak & a spark plug wire missing. No way I came close to over revving it.
Scanned it - Cylinder 5 Misfire Detected.
Sound like the a bent pushrod to anyone? Any chance I'm lucky and this is only a spark plug/wire issue?

Reinstalled, still missed.
Swapped #5 spark plug and wire with #3 spark plug and wire, still misfiring on #5.
Well, at least I know which of the 8 it is...

Valve spring might be the new theory. Just checked it out again, after I revved it up a couple hundred rpms, it almost seemed to quiet down go away for a few seconds, then it came back. Wouldn't a pushrod have a consistent tick all the time?
