issue retorquing head

Postby pschweitzer » Thu Apr 16, 2015 3:28 pm



I have an exhaust leak that I was beginning to tackle this afternoon. I have a few short rides on the bike since I did the top end job and since I have the crash bars and exhaust off I thought it would be a good time to re-torque the bolts. When I replaced the head on the left side, the bolt in the #5 position of the sequence was binding and then slipping right at the 40 lb limit. I think there may have been some dirt on the threads and since all the other bolts torqued up OK I left it alone. Today when I was tightening everything up this #5 bolt slipped again and then went loose. I thought I had snapped it, but I removed the bolt and it is OK (whew!).

Question - All the other bolts in the sequence are tight at 40 lbs. Can I just clean this bolt hole out and reinstall this one bolt or am I screwed and I need to remove the whole head and start over (with new gasket of course). I have not been leaking or blowing smoke from antifreeze, so I think the head torqued down correctly, but is this something that will show up as a blown head gasket later. I don't think the threads in the casing are stripped because I can snug up the bolt.

I did the same thing.The very last bolt.Right at the end and it stripped the threads right out of the block.
Some $50 and several hours later it had new threads in it.I had to drill the hole out and put in 2 helicoils.
If you have to go to that extreme,I still have the special tools and extra helicoils/drill and tap.

Virgil,

I am hoping it is not stripped. I think it never torqued up. It just grabbed and after some heat sequence on the engine, finally came loose. I'll keep the helicoils in mind though just in case.

Flush out the hole,run a wire to the bottom and flush it again.Clean clean clean before you put that bolt back in.

WHEW! Disaster averted. Thanks Virgil! I did what you said and cleaned like crazy, oiled the bolt up and re-installed. Rechecked torque on all the other bolts and this one and all is good. Now back to what I started to do and fix the exhaust.
