Kit looks like it would work. I ended up using a generic ish heli coil kit for the trans mount on my old engine. It held up fine. That's a good price for that kit.

Kinda hard to mess a helicoil kit up, so i say buy it.
I dont know the size of the bolt. There was a bolt list floati g aroubd the net that told the threads of all the motor bolts.

And id buy the kit, its a good price. Id probably use lock tight on the block

You know you can buy different sized inserts seperately, right?

About 10 years ago I bought an engine for super cheap, a D16z6... had some stripped out M8x1.25 holes.

I bought the "ebay helicoil kit" and it worked great.

It might work, who knows. It also might be some super cheap ching chong Chinese shit.

For precise stuff like that, I'd prefer to spend more, get the real deal, and know that the hole I repaired isn't going to strip out again.

Why you want to buy the whole kit. Probably it will be terrible in quality. Its your engine, and later you can have valve bent and serious problems if the tensioner becomes loose.

You can buy specific set for your case. It will be more cheaper and better in quality. You just have to figure out your bolt size and find right set

Fuck the helicoil. Look for a stud with M12 on one end and a slightly oversize thread on the other end. No more worrying about stripped threads, no matter how many times you play with the tensioner.

Today I did reinstalling the timing belt and specially check the tensioner bolt for you.

The stock tensioner bolt was M10x1.25 D16y8 civic 1999ex - just for case

not M12 like you sad before!
