- Greetings Amici, I'd like to solicit the opinions of the group on retorquing the head gasket after the initial heat cycle. I've always warmed the engine to 200 degrees and then retorqued to spec whil

- I have never had a problem with copper gaskets where the mating surfaces were correct. Attempt to retorque resulted in little or no motion on the torque wrench. Of course my sample size is somewhat l

- This implies that you didn't loosen and retorque or remove, lube and retorque. When you try to torque a nut that's settled you are overcoming the stiction of the threads. You'll have to exceed torque

- If you remove all the split lock washers, you must be removing about 5 pounds. That will increase your acceleration. I heard somewhere that Colin Chapman fired a mechanic for using washers on their L
