Default ls/v head gasket problems

well iv now tried cometic and HG head gaskets in my almost factory ls/v any advice on what head gasket to go with next? i was told that cometic was one on the better choices but seem to me the HG (oem honda) lasted longer.

i would say get both surfaces checked and in spec and then a new honda headgasket if you can, cometic if you require a bigger bore.

but also almost every ls/v setup that i have had an experiance with has had or does have a blown hg (leaking oil) problems.

What head gasket are you using? LS or B16/GSR?

I am running an OEM B16 HG on my 81.5mm LS/V setup. It is on a 9.0:1 engine making a little over 500 to the wheels. I have a crankcase ventilation setup on it, and I am using GE dowel pins and ARP head studs. No blow by, oil burning or overheating on a stock sized radiator, oem fan, oem thermostat and oem fan switch. Sounds like you either have a problem with the surfaces or a problem with crankcase pressure. What cams are in it to support that compression?

That definitely will not hurt you. If you are running a b16 or gsr cam, that is definitely building a lot of pressure.

Hard to see, but I have mine plumbed off the front of my valve cover. They are weld on bungs running in to -10 line. I do not have my catch can installed yet in that picture. Here is a link as well to a good thread on Honda-Tech. http://honda-tech.com/showthread.php?t=1970101 56 pages worth of decent pictures.

I do not run any return lines. Between the larger lines basically just moving the pressure and no oil, and the fact that I am running E85, I don't want any of that oil to make its way back into the engine.
