re gasket sealer for plug leak
01/02/09 at 11:13:47

I am getting ready to do my plug /cap leak and in trying to get a silicon sealer the automotive parts store did not have the preferred red high temp silicon sealer so instead I got Permatex Ultra Black maximum oil resistance RTV gasket maker plus I got Permatex Form-A-Gasket sealant just to have on hand in my workshop. Will Ultra Black work OK? I am approaching the moment of truth to do this job, not having a lot of experience doing mechanics.

Hondabond costs more but will come off with ease when you need it too, and it's supposed to be non-corrosive to aluminium.

If you go here:

http://suzukisavage.com/cgi-bin/YaBB.pl?num=1228329607/0#0

you will see that 392F. is about as hot as the area you are dealing with, will get. Its always good to choose a sealant that takes advantage of the latest technology and has a temp rating a good deal higher than your needs. As a sealant ages and as it is exposed to the stress of wide temp variations, it starts to break down. I use this sealant:

http://www.permatex.com/products/Automotive/automotive_gasketing/gasket_seala...

which is rated to 600F.

Perhaps this is all over-kill, but having to do a job over because of material failure, is no fun.

I imagine Ultra Black will work ok, but I would not personally use it. If you look at the directions for use in the technical data sheet

http://www.permatex.com/documents/tds/Automotive/82180.pdf

It talks about finger tightening the flange bolts until the material begins to seep out the mating surface, waiting at least 2 hours, and then retorqing at least 1/4 to 1/2 turn. I think this stuff is designed to be used with stamped steel valve covers or oil pans. I'm not sure if it is the best thing to use with a machined surface like our head cover.

I used Ultra Grey six years ago on my Savage head cover and it is still not leaking. I have also used Ultra Copper in a similar application on an ancient Subaru with excellent results. Like Gort mentioned, you do not want to do the job over. If you have not opened the package, take it back to the auto parts store. Just my 2 cents worth.

Hi Rogue,

If a gasket is called for, I use a gasket. In that case, I do not generally use a sealant (unless there are sharp, inside corners to fill).

For the head cover on our bikes, I use just the Ultra Copper. There is no gasket used for the head cover on my bike (see signature). I'm not sure about the other years of LS models.

IHTH!

Digger, are you using this stuff without any gasket paper at all?

I used it on the head cover and the two engine case halfs. On the side covers, I put a tiny bit on each side of the gasket. Also put some on the head plug.

Not leaks....... knock on wood.

I'm thinking that if it was low profile enough, you might be able to pop it out w/o removing the head cover (if the o-ring ever leaked)
