Blown headgasket (azian6er)
- Thread starter azian6er
- Start date
I am running the stock Head Gasket with an O-Ringed block (at the advice of Perfworks last year 
). I may want a copper gasket one day myself. I'm not convinced that it seals completely. I may have some residue of oil in my coolant, but I am not sure. My car is still fast, so I don't feel any compression loss.

hey Linux, boost controller has two L's 
sorry, just noticed that on the marquee!
i've heard from alot of people that beefy copper gaskets are the way to go on super built applications, etc. Have you done a compression test Linux? btw, how much boost are you currently running?

If the oil is milky or smells really sweet then you have a leak. Don't drive to long on contaminated oil as it will seize your bearings. Personally I'd stick with OEM gaskets but if you do Copper I'd get APR head studs.LinuxRacr said:I am running the stock Head Gasket with an O-Ringed block (at the advice of Perfworks last year

My advise:
1. New Stock Head Gasket they are good for 30-35psi as far as I know.
2. ARP Head Studs (in case you are not going to buy ARP you will need NEW Head Bolts). Remember you are running high boost and the stock head bolts may have streched...so, dont reuse them. Plus you may damage the block.
3. The head needs some machining and cleaning.
I dont think you need a compression test, but anyway, with a failed headgasket, the compression test will be a mess.

My oil is always the normal color when I change it. My coolant stays green. I just may be seeing things. No compression test yet, and I spike to 9 PSI right now. I won't go higher until the new FMIC goes in. I also have no white, or any smoke of any kind comming out of my exhaust. I think the O-ringed block has been saving my engine as well as the J&S. You'd be surprised how much that thing lights up sometimes. With the tuning done this weekend it rarely lights up now. If you don't have one, you don't fully understand the pre-ignition that can happen when you are tuning.ARunto said:
i was already using arp hardware. I will reuse them. SO everyone thinks that the stock head gasket is the way to go eh?
Hey igdrasil, is that one p5 in PR using the stock head gasket? the one running like 30 psi....?
I guess i will just pick one up from the dealer and have my head resurfaced.
What do people think about doubling up on the stock oem gasket? I have 9.1:1 compression right now, but i wish i went lower. DO you think i should try to double up on the oem gasket to reduce comp ratio or not?

Yep I though that too...copper head gasket=better be o-ringed, if not, its going to be warped on high boost. BUT, some people just dont get it O-ringed because in a minimal presence of detonation, the head gasket will go. Something they can repair on the racetrack in an hour and continue the event.
And yes Azian6er, the stock headgasket is a 3 layer metal gasket, boost friendly and the protege5 (which is blown right now) pushed 427hp on the stock headgasket....but on a shot of nitrous it blew it in 4th gear.

I was going to mention this to Linux, actually; If you think that you're getting oil contamination in the oil, I'd think that it might be due to a little damage or warping... Did you get the head decked when you replaced the gasket? If not, that might be why you'd get oil in the coolant, just a little blow over from a warped sealing surface.

Holy crap, man! You're knocking THAT much? That's pretty crazy. Any clue as to why?
I never hear it at all. I do know that I have no oil squirters. Also I have the MP3 ECU with advanced timing. I just probably needed to pull out more timing. I have a feeling things will improve once I get my new FMIC in the car. See my sig for details on that! With the tuning I've done the last few days, it isn't going off much at all!
