When all seafoam has been fed into pcv valve, turn engine off for 5 min.
Turn engine back on, and rev the engine up and let it come back down and keep going until all the smoke clears. Then go driving HARD for like a block or two, reset ecu, change oil, done.
i understand everything except the pour 1/3 into the gas tank.... do i do that before or after the oil change?? will it act as an injector cleaner then??
