JOINTING COMPOUNDS

Post by: **512BB** » Sat Apr 11, 2009 4:13 pm

I would be interested to hear the thoughts of the engine builders amongst us, for recomended jointing compounds to be used in sealing the half moons in place, and the cam cover gasket. No orange hylomar suggestions please, or ill SEE YOU JIMMY, at Donington!

Wellseal

John :wink:

P.S.
There was a thread recently about using a thin smear of engine oil and letting silicone gasket stuff go off overnight instead of rockerbox gaskets...it's good..look it up

Welseal is a favourite. Clear silicone a close second I recon. I personally like to bed the half moons onto a thin smear of clear silly. I do this then let the silly go off overnight b4 droping the lid on. They don't leak that way and they come out easy when you want them to. I tend to use new ones every time but this is just a waste of money. Old habits die hard though.

I prefer the silly option. Any other silly buggers out there.

One silly bugger at a time please

Donny next week...Can u believe it.. :shock:

Struth.

FWIW, I was advised by my local parts shop last week that Hernetite is no longer being manufactured.
ICI Paints has stopped making it because of low demend.

So if it's your favourite compund - get out there quickly and buy some before stocks disappear.

Dribond or 3 Bond 1209 (depending upon where you) are can be recommended.
It's colourless & should be applied only to oil free surfaces.
It's used by the "big boys" & they need a leak free engine "for life"
(e.g. application on "half Moon" elastomer seals.)
The well known & respected sealants of yesteryear, which had oil dispersant solvents, marketed under the same name are still available but due to soddin' "health & safety regulations" have been re-formulated without the solvents.
It is often the case that these products no longer produce the results that could once be expected.

For what it's worth IMHO always use new "half Moons" it's not a waste of money; the elastomer properties do change once subjected to extended periods of heat.

Nix f?r ungut

I am not talking old half moons here. I just put 4 new ones in after 500 mls on the engine. The ones that came out were just the same as the new that went in. But as I said I can't help,myself...

I have loads of them in my 'parts bin' And comparing them its friggin hard to tell the difference.

So.... I beg to differ. Its my money I am wasting but wasting it I def' am....

I think I will start an ebay shop...

C U's at Donington...

I just place the cork on the head and carefully place the cover on and guide the cork in place with my fingers as I tighten the nuts I don't use any thing on the D seals --just 10 pounds of torque on the cam cover nuts ----V.W. rabbit D seals with one lip removed work well also if your in a bind for the seals -----but they are blue ----ed
