Since you won't tell, I did "study".
No meaningful difference . . .
Hondabond HT and Curil have identical service temp and application uses. Both are flexible after cure. HT uses non-acidic silicone and Curil uses a resin - so what.
Seems like Hondabond HT wold be just fine, as would Curil - nothing special about sealing to high-temp plastic surface, doesn't matter if the gasket is delrin, teflon, torlon, techtron, etc. I think I would actually use a silicone due to the thermal expansion of the plastic surface.

If I'm missing something please share...

 

Wtf are you taking about S000Nvegas, If you think that the steel mainfold bolts will reach their creep tempeture before the plastic gasket does, you are smoking dope.

What happens is that the pos plastic gasket can support some torque at lower temp's but as you increase temperature the creep rate of plastics skyrocket. So even if you do not overheat your motor, the plastic gasket will still creep and the bolts will appear loose, when in fact they have not moved at all, rather the shitty gasket has shrunk from material creep under torque.

And it gets worse, if you do overheat your motor, the plastic becomes liquid and begins to squeeze out of the gap between your head and IM, at this point water from your cooling system floods the closest cylinder and you destroy yout motor! Wow this plastic pos gasket is sounding better and better, huh. Especially for forced induction guys whose motors run hotter anyway!

That being said , I would never use this pos gasket, not even on my lawnmower. Just go back to the stock IM gasket, and call it a day. the 1 or 2 hp that this gasket makes is not worth the headaches.

For those of you who dont know what creep is here is the wiki link.

Notice in the article that plastics can creep at room temerature, just imagine what happens at 300 degrees!!

 

I saw it too. Unfortunately the KW kit isn't what you'd call a big hit on the resale market. S.hashan had his kit up for a very nice price and it hasn't sold yet. (not unless it went in the last few days anyway)

I think too many stories like this one is hurting. And people are going to be even more leery of buying the kit that some people believe killed the sellers motor in the first place.

 

Glad you studied, study more, and apply some of it for a few years. Then get back to me. Dont wanna flame away and get off topic. Im known for that.

 

Yes it got hot. According to your theory, the gasket shrunk in thickness .020" ?
Thats all that can explain the bolts being 2+ turns loose by what youve just said.
While im not here to say i know the exact tensile strength of the bolts, i would agree with you that the bolts are far stronger than the gasket.
BUT, you do realize that as temperature rises bolt torque begins to rise dramatically.
*example* s2k intake manifold bolts factory torque is 16 ft lbs. I torque them to 20 ft lbs knowing the gasket will "bed in" within 150 miles. (thus the 2nd torque regimen) That factory bolt will snap clean off at about 30 ft lbs. I havent tested the growth rate on this setup, but if you use other examples you will see, the bolts stretched..plain and simple.
Some examples i know by heart, on an aircooled engine, we torque the heads to 15 ft lbs, at full operating temp, that = 80 ft lbs.
Rocker shafts are similar, torque at 15 ft lbs, and they are near 50 at operating temp.
How does this correlate you ask? avg aircooled head temp is 300 degrees.
HMMM what was jacks head at.....300+ without any doubt. So with that growth rate in mind, you could speculate his intake manifold bolts surely cleared 40 ft lbs, probably toward 60 ft lbs.

Now what was that you were saying about the bolts not being able to stretch????

I know youd like to think i speak out my ass, or you can catch me off guard and be the wiser, but i promise you it wont happen. Am i arrogant, no, just passionate about the subject.

Ask for a stock failure thread and you shall receive.

Nobody here is going to want to see that, as is discredits their inane theories.

 

Does anyone know why this waterpump pulley had only two bolts holding it on?
