Before you read this I'm going to cram lots of info into this small amount of space.

Ok well a while back my WGA got stuck and I pegged the needle on the boost guage causing the car to act and sound very odd. I get home and look in the catch can and see coolant mixed with the oil. So im thinking I blew my head gasket. Car drove fine for a few days so I'm thinking the HG was fine and maybe the quick rise in boost caused the head to lift a little letting a little coolant in and that's how it go into the CC. Took the WGA off and put it back on to make sure it was working properly and long story short it's cranked down a LOT and am gettin an initial 15psi....then it slowly rises to around 18 and then drops to 13-14 at redline. I'm STILL getting coolant in the catch can. The car is NOT overheating and drives totally normal. The only differences are the odd boost pattern, the wga is tighting like 10 times as much and im not getting the same boost, the coolant in the cc and my blow off valve sounds like it's leaking ONLY under partial throttle boost. It sounds like flutter. It does it around 9-10 psi, but if i step on the gas it doesnt leak. It's never done that until the night of the spike. What im thinking is that I may have stretched or weakened the head studs that night and now it's causing my head to lift a little everytime i boost thus causing the coolant in the catch can and the really weird boost pattern and maybe has something to do with the bov acting retarded too. Does this sound right? I'm not sure how long it's going to be until i get to fix this but I want to put some arp head studs and a new HG in it. Also do any of you guys know how much a new head gasket would cost to be installed? This has been pissing me off for about a month or so and i really want to fix it. Thanks for any help

Oh yea i posted this in the problem section also but it seems to be a very slow moving part of the site and I'm not sure how many people actually go in there so i posted it here too.

Well I really dont want to mess with the timing on my car. That's something that I'm not very confident in. I've put a timing belt on my old b18c quite a few times and helped a few friends with theirs but if anything happened and the motor blew or screwed some valves and pistons up that would really put me in a position that I couldnt financially get out of anytime soon. Bump!

Pull your plugs do a compression test...if there is any big difference..you either poped the gasket or you poped the head.....if you dont feel like you can do this, any dealer or trusted mechanic can..the price is minimal....unless you really f%^&ed it up.

I think the head is lifting under boost....even if i do a compression test and everything is fine deep down I'm still going to think i need a new head studs I dont have money to take it to the dealer and the local dealer...well..lets just say one of the guys that works in the shop there told me that "i can disconnect my green line and get 30psi"....im like dude that's the WGA line and you arent getting any pressure to the WGA that's why it's doing that. He's like "yea just dont do it often". hahaha so I dont think I want to take my car there. Anyway does this sound like the problem? I think a cracked water hole wouldnt cause my car to overheat due to loss of pressure in the cooling system? I'm not seeing any difference in the coolant level either. The car also isnt putting out white smoke. I'm trying to figure out what's up without having to pay someone a crap load of money to tell me something. Thanks for input though fellas!...anyone else?

Oh Oh.!

Pull your spark plugs and see if you have one that looks like it has been steam cleaned. :readclose

If so, find a good repair shop to replace the head gasket.

And don't drive around too much if it is the gasket.

the head bolts could have backed off a bitl. find the torque specs for the head bolts, get urself a torque wrench and well, torque all the bolts to spec. theres a specific order in which you torque the bolts. i believe you torque them from the middle out, but you have to torque the exact opposite bolt from the one you started on and so forth.

rough 8 bolt example. numbers indicate the bolt you torque in numerical order.


5 1 3 7
8 4 2 6

that is what i can recal from when i did the heads on my mustang. always try and eliminate the easy fixes first. if the wrench clicks as soon as you try and tighten every bolt, then you can go ahead and replace the gasket.
