I have a spark plug hole that was blown out. I went and got a tap to redo the threads but it's not catching. I'm pretty sure I have to replace the head. Since it's the front head, does the entire motor have to come out or is there a way to do the front while the engine is still in the car?

Maybe tap with a larger tap and use a larger plug??

I would hate to have to pull the engine just to replace the front head.

Given the parts removal and work required to replace the left bank cylinder head you would be better off dropping the drivetrain, removing both heads and studding both banks at the same time.

If the rest of the car is in Very Good to Excellent condition it's worth the job. If the rest of the car is not in top condition, you might go in over your head cost-wise, but that's your personal call.

Ask a good mechanic or dealership if there's a HeliCoil spark plug hole thread repair. There may be one in the GM service manual. May .....................

Helicoil was purchased at autozone for $27ish. Was fairly easy to use.
