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 |

Used a TimeSert to do the same thing. I had to drill out the old broken CHT first. The CHT hole has a bottom so measure and use the tape trick for the drill bit, if drilling, and on the tap. TAKE YOUR TIME and keep the tap perpendicular to the hole. Here's a pic.
