datz280 Posted June 13, 2007 Share Posted June 13, 2007 I have read about the use of the HKS 1mm head gasket and also o-ringing the block. Are these two procedures mutually exclusive? If they are it seems more people are using the HKS. Quote Link to comment Share on other sites More sharing options...
joe d. Posted June 13, 2007 Share Posted June 13, 2007 I had a 582hp turbo civic (prelude motor) and it was o-ringed. never had a problem with it until i pushed it to 32psi. then the oil and water mixed. Quote Link to comment Share on other sites More sharing options...
Tony D Posted June 13, 2007 Share Posted June 13, 2007 No, they are not. But I know plenty of L-Engine people running HKS and no O-Ring. They really are a stopgap...If you misfuel and detonate, something is going to break. If you O-Ring, it will be your pistons, regardless of what super-duty unit you have. With just the HKS, you might blow the head gasket, but unlikely---JeffP sunk the ring lands in five pistons without ever hearing any detonation whatsoever...plain old HKS Gasket. So it's more overkill than anything else. Properly fuel your engine, clamp it to the block properly with good fasteners, and either setup will provide yoeman service. Detonate, and it doesn't matter what you have, something is breaking, likely expensive pistons. Personally, I'll prefer to blow the head gasket and save my $100 per pistons!

zguy36 Posted June 14, 2007 Share Posted June 14, 2007 I blew a steel o-ring with copper head gasket. The gasket shoved right out past the o-ring and the o-ring fell into the combustion chamber. This was all on stock turbo pistons. I swapped to the steel hks gasket and am still using those same pistons. Quote Link to comment Share on other sites More sharing options...
gjc5500 Posted June 14, 2007 Share Posted June 14, 2007 o rings will take more abuse. problem with that is that you will prolly blow ur ring lands or throw a rod if you detonate Quote Link to comment Share on other sites More sharing options...
jgkurz Posted June 15, 2007 Share Posted June 15, 2007 I chose to o-ring my block and use an OEM Nissan head gasket. I have JE pistons and so far the engine has held up to as much as 25lb boost, one overheating and some abuse early on when I didn't have an intercooler. I agree that nothing will make your engine detonation proof. Better components will probably take the abuse longer but still will eventually fail with poor tuning. No one has mentioned it yet but using studs rather than head bolts will make a HUGE difference in keeping the head gasket in place. Quote Link to comment Share on other sites More sharing options...
datz280 Posted June 15, 2007 Author Share Posted June 15, 2007 Thank you all, I think I will go with the HKS and ARP studs. Quote Link to comment Share on other sites More sharing options...
