has anyone have their spark plug blow out of their head ?
is a heile coil the easy fix or the head has to come off

I have a v10

 

Do a search in the V10 forum. You'll find plenty of info. It was more common in the 99-01's. After that, more threads were added to the head and that seemed to help alleviate this problem.

No, you shouldn't have to pull the head. I think the repair is called a timesert. It's similiar to a heli-coil. Check the V10 forum. You'll get all the info you need.

 

Time sert is the way to go.

 

had all plugs replaced and a timesert done for 300 bucks when i blew original plug at 130,000

 

well I was lucky , I was able to use a thread chaser to clean up the threads the plug tighten down seems to be working find
