318 popping in left bank header under load. Look at my plugs

It looks like mud. Tell something you've seen like that before that isn't a million mile motor , exaggerationwith issues.

Yes. Hung open, under some load will pop out the exhaust. Not at idle, just under throttle. Could be your problem.


You know I just took the previous owners word that the 50k mileage is legit as they were first owner but maybe it is high mileage. it doesn't use any oil.

Meh I was planning a amagnum swap for this winter. I'll do a compression test and leakdown test.
