Whats the best sealant for head gaskets

[Burt Reynolds]

Hylomar blue or red, Hermatite Red, Granville silicone clear? Putting back a cologne v6..putting the standard gasket set on but i wanna whack some muck on it too just to make sure it does the job. Ta

They shouldn't need any. Just make sure that the mating faces are perfectly clean and that the heads are flat.

I agree vista especially with modern engines and there machined tolerences . My old boss used to work on classic jaguars and would always use wellseal on the head gaskets , its the only compound he would use.

Personally I try not to use any sealant, even on turbo apps, and have never used anything on a cologne lump.

 

A mate of mine though swears by wellseal and slaps it all over his cossie builds

Ta. Gonna not use anything on the head gasket, but i've use hermatite red on the water pump already. Haven't tested it yet.

The fun with red hermatite is separating the two parts! it used to always be used by the old boys doing their 10,000 mile de-cokes on the old 40's and 50's cars, all the Monday morning stories of removing the offending cylinder head with a hammer and chisel! all right for steam engines I guess.....

The smell of red hermatite and petrol reminds me of when I was a kid fixing motorbikes in my dads shed

Well, i have the sump gasket to do, the front crankshaft pulley washer/seal, the rear crankshaft oil seal, the timing cover and metal adapter plate, the head gasket and plenum gasket to do. I've got a tube of Granville Instant clear silicone gasket. I aint got a clue how good it is, but i might just give it a go. I used it for my type 9 gearbox, I smeared it over the bolts holding the nose cone in place, the cork gasket holding the nose cone, the gearboxk top cover and the speedo blanking plug..I aint tested it yet though. I ran out of the Hermetite, and to be honest i don't like the gear. Anyone used Granville - would it be ok? Obviously i'm not going to use any sealer on the head gasket.

use a light smear of blue hylomar,either side of the sump gasket .and a little bit more where the sump gasket meets the front half moon seal
