Head Issues OMG

[dazza33]

I was putting a head back on tonight and i found that i seems that i have a stripped thread in the block? I definitely didn't do it and when i think about it i thought it strange that it was really loose when i undid it. Is there anyway this could happen without over tightening it? And well, is there a fix?

Cheers, Daz.

theres 2 possible fix's.

1. re-tap the thread in the block and maybe have to get a thicker bolt.
2. use some locktite.

Id say if it was like that before you undid the thread, the last owner or whoever worked on the heads previously didnt use a torque wrench to tighten and overtightned it.

Using Locktite still won't allow me to torque it will it?

[Ozzie]

Nah... the only way youll be able to torque it is to re-tap the thread.

You could try thick thick plumbers tape on the thread and some locktite.

You might get away with a bit of tension and the locktite will hold it.

you can use a helicoil to fix it . You will have to drill the hole bigger and screw in a helicoil to suit , A helicoil is like a thread that screws into the hole . Most engineering places like Blackwells sell them.
