$300 for a stripped spark plug housing thread repair?

[treesmith]

that $300 would pay for a port job from Randymind which gets you a lot of work hence why it seems a bit steep to me

Whether its a $30 fix or $300.....remember not to do up your plug so tight. My guess is 90% of folks over tighten spark plugs, it can be a costly practice.

When using the scrench to tighten them, I snug them up and give the scrench handle a good tap with my palm and call it a day.. never stripped one out yet

 

[cutforfun]

Most striped out plugs I have seen are from the plugs not getting tight enough. Then rattling loose and beating the threads to death

I've had great luck with Timeserts in the past. I'd really like to give Keenserts a shot some time, they look to be extremely well constructed.

The best locally available kit is the heli-coil or misc brand Sav-A-Thread kits. Unlike normal heli-coils these are a solid insert (not wire) and have a serrated lock on the top that you swedge in after installation.

If you do an insert with the jug on put some grease on the tap and it will pick up most of the shavings. Do the work with the piston rings just above the transfers (check that cutter clears) then blow out/rinse with air/mix through exhaust.

If there is a market for putting in inserts for $300 I'm in the wrong profession..........

Besides loose plugs, gorillas, or cross threads, the aluminum threads seize onto plugs that lived there quite a while and were not installed with an anti- seize

Srcarr52,

That is exactly the type of insert I was talking about in my original post. Couldn't remember the name of them, thanks.
