if you pull the dip stick does it puff too? then it would most likely be rings..
if its only in the top end it could be valve guide seals? but even so it should NOT do that unless the valves are still bent.
its not back firing through the throttle body? does he have a cylinder leakdown tester?
No puffs from dipstick tube, no backfires through throttle. He did say today that letting it idle for a bit has helped. Perhaps the valves need to break in the new seals? I had the bent valves replaced. New plugs and wires are going on. It's starting up just fine now. The engine coolant temp sensor want plugged in so it caused the ecu to dump too much fuel and foul the plugs.
Put new plugs and wires and it runs a lot better. We removed one of the hoses for the PCV system and it was not blowing anything noticeable. Same thing with the oil cap.
did you have one of the wires crossed?
No idea.
Step dad drove it today and it stalled twice. He said the RPM's seem to be a bit higher than normal in idle and the other time it stalled the RPM's were a bit low.
only thing i could think of, if you hooked everything up (i still miss stuff, so i am sure its possible for you) and the "internal" is correct, is that maybe your temp switch doesnt work correctly now that it dried out with coolant removal. ive seen it before on other cars.
it could idle high stuck in warm up, then cuts too much fuel when it finally changes to regular running.
no codes or anything yet? 3 cycles. you might just need to do a relearn of something as well.
Check engine light is on. Going to get te codes checked at autozone and stop by the shop Monday. My step dad said it stalls when he slows down. The rpms drop really low and it dies.
Still throwing a p420 code.
secondary o2 or a clogged cat..
