I replaced the front crank seal on a d16y7 and all went well until I went to tighten the timing belt tensioner and the bolt hole stripped. Has anyone had this issue on the tensioner? Did you tap it out? What size, new bolt, and how deep did you tap it?

 

You should get a timesert that is the same size as the stock bolt. Then measure depth of bolt hole before you drill out for the time sert.

The kit is not cheap but it is the BEST solution for these kinds of issues.

 

Yes, use a TimeSert.

 

I plan on swapping for a b series down the line in a few months. What’s your experience with helicoils? I’m trying to stay anyway from that $130 part that I’ll probably need just this once. Do you think it would hold? As it’s not a daily and I don’t plan on running it hard.

 

The stock bolt specifications are 10-mm X 1.25-mm (Honda Part# 14517-PG6-000)

I don't know the length. You can purchase the bolt from Honda for $1.50.

 

That should work fine, I use them on striped exhaust manifold threads, same concept, you drill out the bad threads and re tap the hole and insert the coil and use the same size OEM bolt.

 

I put a helicoil in and it held just fine. Ran it down the road and back as it’s not legal yet. I will update how it holds over the next few weeks/ months.

 

Should hold okay. The timesert is a more permanent type solution, closest thing to a welded solution.

You could make the helicoil closer to a welded solution with some crafty JB weld or red loctite on the outside surface of the helicoil but really, you should be fine.
