I was just changing out some plugs on my ranger and I stripped one of the cylanders where the plug goes in. It still goes in but is a lose fit now, what should I do?

 

Heli-coil it.
You'll blow the plug right out if you don't

 

yep get a helicoil. it will possibly fix it.


if that doesnt work, your gonna need a new head. (not cheap)

 

helicoil is fine not that hard

 

thats why when i take my truck in to have the tranny flushed, the dealer is changing out the original spark plugs lol

 

this is why you start the threads by hand.

 

And most importantly, if you pull the plugs out of a warm engine that has aluminum heads, don't reef on the ratchet when you're putting them back in. A light snug down is all.

Cold aluminum heads, medium snug down on the spark plugs.


On a cast iron head, don't get all fussy, just put them in and snug them down well.

 

the hole can be welded up and remachined... or a new head. i personaly have never buggered up spark plug threads... but i have buggered up a few other holes in my lifetime.
a "time-sert" would be my first choice as its cheaper. and "I" would take the head off to do it, it can be done while on the motor. time-serts and heli-coils require drilling and tapping, plus the "tang" on the end of the heli-coil needs popped off. this alot safer to do head in hand.
good luck grasshopper!
