Headgasket change question
- Thread starter huntin5L

I see permatex makes a whole bunch of gasket sealants. http://www.permatex.com/products/prodidx.asp?f_call=get_item_list&item_name=Gasket+Makers
brake quiet are you sure it's just brake quiet? I can't get past this, isn't it just an alcohol based mixture used to get grease and stuff off your brakes? If so, how can it create a sealant for the surfaces? Why not spray pam on it instead?

The brake quiet is not actually a brake cleaner. It creates friction between the bad and the rotor. I used the brake quiet method on my cometic MHG. Brake quiet sprays out blue and after sitting for about 2-8 minutes it starts to turn tacky and adhesive. From what i've heard, the brake quiet does the same exact thing as the copper spray, but is not as easily deformed by higher temperatures. I have no idea what its chemical properties are, but if you cant find it in stores through the aresol can (the only way i'd go), then it can be found at an online store called midway. I hand lapped my block (with sandpaper wrapped around a piece of glass to keep it flat. I started at 600 and worked my way to 2000 grit, but come to think of it i should have started at a higher grit.) and then i used brake quiet. I also had the head lapped and resurfaced that (with the same method mentioned above) as well. I just passed the 1000 mi mark with no problems yet.

none of those, that i know of, are for use on headgaskets. I know of a few of permetrex's gasket products which say something like 'avoid contact with gasoline, not permited for use with headgaskets.' As far as sprays on MHG's, i'd say that brake quiet is the way to go. Its become somewhat tried and true.
Ummmm errrr not wanting to be a smartarse or a knob about this but you DON'T put brake quiet on the friction surface of a brake pad......
It's sprayed on the backing plate of the pad and works by gluing to pad to the piston so when the piston retracts (square seal in the calliper pulls it back a few thou when you take your foot off the pedal) it pulls the pad away from the rotor and stops is glazing and squealing.

Ohhh, i guess i never used it for what it was intended to be used for. Thanks for the correction. Next time i'll read the directions before trying to explain it. lol.
LMAO I just had this horrible mental image of a kid reading it buying some to put on his pads and T Boning a bus full of Nuns at a stop sign !
i guess literate people are hard to come across these days lol it says how to use it in the instructions (for brakes that is)
bars leak will fill any hole/gap in METAL areas of your cooling system, including the head. They do use it for radiators but can be used for anything. Like i said even if you do have both block and head milled, my local supra shop reccomends to use bars leak anyways, because mhg's just don't seal that great. Make sure you get the liquid metal type, and not the copper. The copper has been known to clog the radiator.

This is where i got mine, none of my local stores carried it either. I got 2 cans just to be safe. The first one ended up being defective, it was a good call.

Yes, as a matter of fact the nozzel broke at the bottom and sprayed sticky brake quiet all over me. I was a mess that night. BTW buy some acetone just in case you screw up, it will take off the brake quiet (but i dont know how acetone will affect the rubber coating on some MHG's).
