While driving the GN home last night, I accelerated to get on the freeway & heard a slight pop, a quick puff of light colored smoke came into the cockpit through the dash, but quickly disappeared... The car sounded as if I either popped a headgasket, bent a valve or something???
Exited freeway & coasted(car still running) into a parking lot...
Observations:
Could hear a tapping noise from under the hood...Took a 3 ft piece of garden hose I had in my trunk & with one end up to my ear & the other searching for where the tapping noise was coming from, it seemed to be right in the top center of the drivers side valve cover. Tapping speeds up when I gave it more throttle.
Couldn't really hear any exhaust leaks when searching around the headers or head..
no smoke out exhaust
Oil looks nice & clean
oil pressure normal (25psi)
engine temps normal(175)
BLM's went from 125 to 142... ???
Shut the car off & had it trailered home by a friend...
This morning I pulled the drivers valve cover & took off the rockershaft looking for cracks, but it looked fine
Pulled the pushrods to check for straightness...they all looked good
I don't see any headgasket material coming out from around the mating surface...
Could be a bent valve or collapsed lifter? Maybe still a headgasket?? Someting else??
