Re-torquing head gasket before turbo install?
« on: October 31, 2018, 09:34:18 PM »

Whats the consensus on retorquing the head gasket before sending the boost at it, and if its yes, what is the best procedure?
My 8v was rebuilt 12000km ago with the stock gasket.

The concept of no re torquing is a hot topic for sure. Itís not the metal crush thatís an issue itís always the fiber that blows out whether turbo or not. The fact is that when it usually takes up to 80 lbs to release a factory head bolt it makes no sense to torque a head gasket to 52 lbs. if you want to have a better chance of your head gasket not needing replacing, you can always buy a $99 head stud kit. Replace one time at a time and when all in crank it down.




All first installed reman ZOR engines should be torqued right after first few start ups to check for leaks and details.  Get to normal temp and while hot torgue to 52-55 and then let it cool down. That is a part of why it takes so much torque to remove.

So arp studs, one at a time to 52 ftlbs, then in proper torque order, take all to 80 ftlbs?

I wasnít clear. Point was they are a lot tighter than 52lbs that the books say to torque the head bolts. With studs going to 60 is fine.

Your reply is procedurally correct
