What would you do?

 

I can't tell but I'm assuming it's stripped? If so, try your luck with a helicoil.

 

Are you talking about the gouge in the mating surface?

 

I have the perfect fix for you. This happened to a 2001 Civic LX I worked on. I started to do a timing belt replacement for someone who became a friend because he had a blue 88 HF just like mine and I offered him $4000 for it. He turned it down. The car was totaled right in front of his house while he was out eating breakfast. He had it parked out on the road and some lady avoided a "squirrel" and ran into the rear of the CRX. Story gets longer but I will instead tell you how I fixed his car.

So, the timing belt would not tighten up when I went to torque it down to 33 foot lbs I believe it was. I pulled out the bolt and it had a helicoil already installed on it. He claimed only Honda worked on his car but the replacement timing belt was not a genuine Honda belt, it was an auto parts brand belt. Someone is not being honest with me. So, I knew if this helicoil could come out once, it could and would come out again.

I searched and searched and searched some more to find a better solution. I found these. Time-Serts. You use these on virgin holes. Mine had a previous repair done so I needed the Big-Sert.

I found the video I watched before I bought this product.





The kit is about $80 bucks and it is as strong or stronger that the original threads. I was extremely satisfied with the results and I would use this product every time I needed to do this type of repair.

Amazon or EBay will likely be the cheapest place to pick up a kit.

Block cracked, weld? Jb weld?

 

it's only the block? I would deburr it and call it a day. It is not going to affect it. The JB Weld will come loose and likely cause problems.

 

Basically its creating a non flat surface for the tensioner to rest against, when tightening the bolt the tensioner wants to twist when pulling the tb tight.. ive never used a helicoil, and this is not my motor, i told a friend it would probably be better to weld it shut and then drill and tap it again seeing how you dont want your tensioner off or to fall off while driving... so we go through the whole process of rebuilding, and while installing the tensioner this happened.. as of so far they jb weldes the broken threads that chipped out of the bolt hole for the tensioner.. when i look in the threads it doesnt look like the bolt is going to line up, let alone hold tension... im just trying to help out a friend fix it the best way, as he cannot afford to have a timing belt falling off after all weve done..

 

After, i dont know i don trust it

 

^^^ did u JB weld it?
