Blown Head Gasket?
 

- white smoke (especially at idle)
- 90s across the board for compression.
- Hard to get started, Sounds like a subie when it finally starts.
- Runs like ass.
- Coolent is running a little hot.
- Evo 3 Metal Head Gasket that has been on a couple of my engines, and head changes, Applied Copper Spray this last time i put the 1g head on. The normal sealant was looking a little tired.
- Torqued and retorqued to 76 ft/lbs.
Sound like a head gasket to you guys?

Re: Blown Head Gasket?
 

I would say so, i would get away from the metal head gaskets in my opinion

Re: Blown Head Gasket?
 

agreed, also maybe every once in a while when your changing your head/engine you could pick up a new gasket.

Re: Blown Head Gasket?
 

Reused head gasket? :nope: :rollinglaugh:

Re: Blown Head Gasket?
 

lol! Reusing a headgasket? You have got to be kidding me.

Re: Blown Head Gasket?
 

This guy never catches a break.

Re: Blown Head Gasket?
 

You can reuse metal headgaskets, I've done it several times with no problems. However going with 76 lb/ft is a little weak in my book. I torque my ARP's(used several times as well) to 95 lb/ft with oil.

I did have mine go early this year with no real explanation, I wasn't on it at all. The only real thing I can think of was I had my timing set up wrong in link. The symptoms were exactly as you're describing.

Re: Blown Head Gasket?
 

Naw, it's fine. Keep running it until it's down to running on 2 cylinders instead of just 3 and it gets enough coolant in the cylinders to bend a rod or two.

Re: Blown Head Gasket?
 

Thanks, Yeah i have never had issues with compression until this last time. Ive always made sure to put a nice coat of Copper Spray on the Head Gasket and never had any issues. Looks like im going to have to take the head off AGAIN!

Re: Blown Head Gasket?
 

And while your at it, make sure those headstuds are a bit more than finger (76lb) tight :).

Re: Blown Head Gasket?
 

I have reused them before. the one on the talon has been off 4 time still same multi layer and seals fine still with copper spray and arps down to 95

Re: Blown Head Gasket?
 

Stock headstuds. And i really dont want to snap them.

Re: Blown Head Gasket?
 

Reusing metal headgaskets is nothing new.

Re: Blown Head Gasket?
 

You're using stock headbolts? I thought you were running in the 20s for boost, maybe they stretched. With all this money/time you put into it, should splurge for ARPs.

Re: Blown Head Gasket?
 

Yeah i run 25-27 daily.
I may pick some up, otherwise i think i have a set of 6bolt ARPs to go with my 1g head. I would have to tap the block though.

Re: Blown Head Gasket?
 

You can't reuse stock head studs! Spend the $80 for ARP's and save yourself all this hassle.

Re: Blown Head Gasket?
 

Cant = Shouldn't. I know you shouldnt but these have worked fine for the time they have been on the car. Yes im planning on getting some ARPs now and a new metal head gasket. Anyone know the mitsu part number for the evo 3 head gasket?

Re: Blown Head Gasket?
 

nm found it Part no: MD349347

Re: Blown Head Gasket?
 

You can reuse the mitsu metal mutli layer HG? That would be news to me.. I dont think id ever reuse something that critical.

Tom, I thought you were getting out of dsms. :P

Re: Blown Head Gasket?
 

Metal head gaskets dont blow like oem ones, so usually you can copper spray them and it will still seal just fine. But the raised sealing material has wiped off after using it multiple times.

I have tried many times to get out of dsms, but i just cant give up on a car that is:
a) Completly paid off
b) i have spent so much time and effort on. (and money)
c) usually works.
d) has everything i have wanted in a car.

Re: Blown Head Gasket?
 

Here is a tip. Don't reuse headgaskets, don't copper spray. Make sure your block and head are perfectly flat. Make the surfaces clean enough to do surgery on the on them or at least eat off of. Copper headgaskets don't work worth a crap unless you have an O-ringed/receiver block/head, so do you expect some copper goo to hold back 2500psi of cylinder pressure? It CAN do more harm than good. I would only use copper spray or a sealant to stop oil drain hole style leaks that cars like Hondas get at the corners of their heads. If you insist on spraying your entire headgasket with something, at least use a product made for that, it's called Hylomar and Valco sells it in spray cans. It's made for headgaskets and it can handle higher temperatures than copper spray. Or go buy a nice new Cometic MLS, they come with a Viton sealing layer on them, they don't need to be re-torqued, and when installed CORRECTLY to FLAT surfaces, they will handle 40+ psi no problem.

+1 The bolts stretch when you torque them down. Then stay stretched when you remove them. Then stretch even more when you re-use them.

Re: Blown Head Gasket?
 

Stock head bolts are stretch-to-yield, meaning when they are torqued once they stretch. That 76ft/lbs you put on them this last time more than likely was far less than that.

Get ARP head studs, use a new head gasket, torque to 95ft/lbs. Do it right for once and quit disassembling your car to fix problems that should not have occurred in the first place!!

Re: Blown Head Gasket?
 

OMG, I thought you had ARP's in there...sigh...

Re: Blown Head Gasket?
 

Re: Blown Head Gasket?
 

Nah i had arps on my 6bolt, but havent done it on this block yet. Prior to all this bent valves and swapping to 1g head, the compression was exactly 125 across the board.

Re: Blown Head Gasket?
 

LMFAO! at Matt D.'s last comment

Re: Blown Head Gasket?
 

all i gotta say is WOW.......

Re: Blown Head Gasket?
 

Tom never ceases to amaze us :D

Re: Blown Head Gasket?
 

Just buy a honda and daily drive it and DON'T modify it since that's where your car seems to go wrong

Re: Blown Head Gasket?
 

LIKE YOU CAN TALK!!! Ill remember that next time you need work done.
