about 3 years back I tore a motor down to rebuild my rebuild.... (long story)
anyways, I only have myself to blame today I started bolting on the externals and tin found out that the CHT hole is stripped. motor is assembled and I really don't want to pull the head at this point for welding...... how do folks feel about a time sert or a heli coil in this application. I think I happen to have a heli-coil in the right size... but if I had to buy a time-sert to make it conduct the heat into the sensor I would do it. what do folk think? John, how would you tackle this repair? thanks in advance everyone. brant |

Helicoil would be fine. Brad Anders has found that the CHT heats up too fast in some cases and adds a spacer to keep it cooler longer. But I doubt you would notice a difference in CHT function.
Just don't drill too deep or you'll go into the combustion chamber. (IMG:style_emoticons/default/yikes.gif) Measure the depth of the OE hole, and put some tape on your drill bit to keep from going too deep. |
