blown mhg? need to fix? how to:

[ma70t]

i use Cometic on one of my customer car he's boosting 20psi all day for the past 3 yrs no problem so in my book Cometic is just as good its all in the prep work just like a paint job no matter how good a painter is but if the prep is not done with care then the paint job is going to look like sh#!

but I'm use a F.E.T mhg

FET looks good.

Theres a new brand out there called "Nippon Racing."

Quake: Google Darin Darchina, and Sean Joseph. Those guys are putting down more power than you with no worries on the T.M.S. gasket.

This thread isn't going no where IMO. People who follow this will post a few months later asking why they ran over their new fancy connecting rods when their AFR's read Lean. But no worries the HKS Stopper MHG is fine and ready to be reused!

i got the fet like 4 yrs ago had it for a long time

I know who darin is and have spoken to Sean many times. I already stated this was my opinion take it or leave it. I also never said how much power I make now. I could put together a car tomorrow for 1500 rwhp but that is not my goal. First off I want my car to road race, drag race, and street race. It's a tall order but above all it needs to be reliable, make over 550rwhp on pump and take a beating all day long everyday. It does this and has left me stranded once in 3 years from a failure. That failure was my msd dis-4 I had it fixed and picked up a second to leave in the car just incase. You see what these guys fail to realize is a head gasket can fail more than one way. I never gave specifics they just assumed and you know what happens when you make assumptions... :nono:The gasket could leak combustion gases between cylinders this you wont pick up. Maybe it only leaks under high boost, or a boost spike. It's not just always a coolant issue. If the gasket you use works for you and you are happy then by all means leave it in. At the end of the day the stopper has a better seal than a bead type that is all I am saying. As far as afr's go if you run too lean from a bad tune that is on you, I would hope the tune would be good after spending money on the right go fast parts. By the way i am fully aware that you can blow a hks stopper, just not as easy as a crappy bead type.

As for the spray I have seen pro builders use spray on 20,000 dollar motors without a problem. However I use it for my own reasons and it won't be the deciding factor on your combustion seal. Are there chemicals that can attack the viton in the spray? The bench racers say so and I never said I don't agree. The real question is at what concentration, if they knew that they would be ceo's of spray sealant company's lol. Rat poison can kill you too but at what concentration? Maybe one of those guys can tell me how long it will take for my gasket to turn to goo. I'll give them a hint it's gonna take more than 20k and 1 1/2 years over 600rwhp :biglaugh:

3 Yrs on a stopper not 1 blown head gasket and i could reuse it...oh yeah i just wanted to add i saw sean run his MKIII on the dyno he made 2 runs and on the 2nd the supra had to be pushed off dyno...i dont even think he saw 500hp...but none the less hes a great guy plenty of knowledge....

 

[supisarethebest]

whos the LAPTOP NINJA!?lol

 

[supisarethebest]

both parties got a bit heated about this discusion,lol,this argument was entertaining to read cause im on my fourth hg in 2-1/2 years.....p.s i dont do my own work bcause i dont have the capability,knowledge and time so dont start attacking me!

 

[Zumtizzle]

quake. I know you're a "higher" hp member.

I'm going to stick with my HKS Stopper. (I'm getting it for cheap. )

But the Cometic/TMS/HKS/Greddy Beaded gaskets aren't "crap".

 

[supisarethebest]

bump,haha

 

[toyotanos]

cometic has 3 layers a 1 shim and a top and bottom layer makes 3

I'm sorry, I was mistaken. The 4-layer gasket I was thinking of was Sean's HKS Stopper. My Cometic has 5 layers (not 3 or 4). Top seal, shim, middle seal, shim, bottom seal. Here's a picture, taken in my garage not 2 minutes ago.

 

[airhead04]

What size gasket is that?

 

[toyotanos]

2.0mm, 84mm bore Cometic. Big time zoom-in on macro.

 

[airhead04]

Nice, thank you.

2.0mm, 84mm bore Cometic. Big time zoom-in on macro.

Custom made?

SIP racing?

There isn't a off the shelf 2.0MM Cometic.

 

[toyotanos]

It isn't anything special that I know of, I was there when my machinist called in the order and it arrived 2 days later. But hey, I haven't been around these cars as long as others...

i only see the 2.0mm in a 86 bore, maybe some sizes are not listed?

Notice it Says. "Usually ships in 5-10 Days"

You order from JSC and then they order from Cometic.

thats not what i meant by layers i take it you did not install it if you think you got 5

My Cometics/TMS have always been 3 layer no matter the thickness, 2x shim 1x spacer, only 4 layer MHG I've personally see is the HKS Stopper 2x Shim 1x Spacer and 1x Firering Shim.
