Answer 1

Favourite answer

Spark plug recesses are filling with oil from the failed gasket leading to misfires.

Answer 2

Push all the spark plug wires onto the spark plugs firmly.

If it doesn't cure the problem then bring the car back.

Answer 3

If the car is running bad after changing the plugs have you checked to make sure all the plug wires are pushed on tight...OR...maybe the guy pulled on plug wire instead of the boot and screwed up end of the wire so its not making a good connection...OR the plug gap is wrong...

Answer 4

not a rocker cover gaskit. the worst that could happen there is an oil leak

Answer 5

the rocker gasket would be because its leaking oil it won't cause poor performance.Type of car would help as we don't know what type of ignition system you are trying to troubleshoot

Answer 6

No. New plugs should not cause loss of power unless they were incorrectly gapped. Maybe the ham fisted grease monkey damaged the HT leads or more likely swapped a couple. The gasket has no effect whatsoever on power. It just retains the oil present around the valve gear. Take the car back and ask the boss to investigate.
