SignUp Now!"Torque to yield" bolts. That means when you torque them they stretch which means that when you take them out they are already stretched and don't "unstretch". If you reuse them you will NOT have proper torque and you have a real good chance of losing a head gasket. Don't try it, they're not that expensive.
If it's not broke, don't fix it.
"If it ain't broke, fix it til it is!!!":biggrin:
Um, he is asking about reusing headGASKETS, not bolts. :biggrin:
I have heard it is safe to swap one bolt at a time, going through the torque sequence and doing the new bolts in 3 steps like you normally would. I have not tried it, not really sure I would. Depends on how hard you will be pushing your car. If it was a driver with stock boost levels, I would think it might be okay to do one at a time.
My Bad! Misread the thread. sorry, maybe this helped someone else thinking of changing head gaskets and thinking of trying to save a buck on the bolts.
Then after letting them sit for 20 minutes, loosen each one individually and re-torque to full torque value. Do this one at a time, too. This will help "set" the bolts. If you want to see how much they move, mark the top if the bolt with a silver Sharpie pen and then see how far it moves when you loosen and retorque. It is amazing how far they move.
well im going to run about 26 pounds its my summer car my other summer car is getting boosted and will be done by may
