Hello,
New to this group, sorry if this is off topic. Was working on a Honda aluminum motor. The head bolts are hardened steel 12mmx1.5.
Some metal pulled out of one of the bolt holes when the head was removed. Uh oh. I guess 200K seized them a little bit. Upon reassembly, that bolt pulled out at final torque. Doh!
Big problem: the threads start about 2 inches below the deck surface. Can't reach the threads with my tap or with the helicoil tools.
Timesert makes a kit (the Honda Odyssey kit) that would work, except it costs $400 and is for pro rebuilders. I am a do it yourself hack.
Can anyone recommend what to do in this situation when a helicoil or EZ lok is necessary and the threads are so far down inside?
The motor works fine and would be a shame to have to junk it over such an annoying issue. That's throwaway engineering I guess.
Thanks.
