T-REX cylinder head studs pulled out!

[scotties_banshee]

Hello, I pulled 3 of the cylinder head studs outa my T-REX cylinders. All 3 of them were helicoild in!! Do the T-Rex cylinders comelike this from factory? So it tore the helicoil out along with the material around it. So know i have 3 ,clean round, holes with no threads in it, how do i fix this????

no they dont come like that from the factory. where did you get the cylinders from? thats what people do when the hole gets stripped out. I used to have a t-rex cylinder and it did the same thing. the exhaust flanges also did that.

You have to get an insert, I hate helicoils, they do work ok, but the inserts is for sure easier and stronger. Insert is a small sleeve with thread inside and outside and you do get thin wall inserts, try contact Wurth, they sell kits.

Scott,

Try the inserts from Wurth...use a little red lock tight on the insert...

And dont torque them too tight...I skip the torque wrench and just use a boxend or ratchet...go by feel...the o-ring heads seal much better than the stock gaskets.
