Yip I helicoiled mine.. The helicoil itself is about $50.. Make sure the piston is all the way to the top, drill and insert the helicoil with some red loctite. Blow out all the metal shavings and anything really tiny should just blow through your exhaust. Make sure to add a little anti seeze to the plug and your good to go.. I've gone about 18,000 miles since. |
