Striped plug help

[Drone51]

think i started to strip a plug in the head the plug dosnt looked striped but i thitnk the threads in the head are a little what do i do

[geocor]

buy a plug thread chaser ,any good auto parts store should cary them. remember to put grease on the chaser so thread material doesn't get into the cylinder!

If they are starting to strip, be very careful in the future....that can turn into a MAJOR problem. When I worked at Autozone, we had some thread chasers and then some inserts that go into the hole after you chase the threads. The kit was cheap and it is a pretty simple fix.

try out a thread chaser first. if it becomes apparent that that won't suffice, you can always install a helicoil. i've used them quite a bit on aircraft cyl heads & have had no problems. i've had a lot of experience with this & would not recommend a n00b doing this, as you can fuk stuff up pretty quick.

you "can" do it without removing the head (i've never removed a head) but you want to be sure to borescope the cyl before turning the crank at all. if someone inexperienced is doing it, i would definitly remove the head.
