it cant hurt to use some sealent, i used rt n mine, it hardly leaks, well a drop every now n then

[liirge]

In one of the haynes manuals I've got they say you should use some RTV or similar around the half moon seal anyway. I use sealant..and not had any gaskets leak!

[Surfbluegarage]

exactly... and on the diff housing seal your not meant to use any gasket 'just' some sort of sealent

[paul6266]

not superglue then lol, yeah i would agree use HYLOMAR as thats the best stuff, used it on many engines and never had any problems

[Pauly]

Know where I can get rtv in the long tubes for the sealent guns?

[Owen]

Tiger seal seems to work well!

[mk1leg]

Hylomar is the best to use as it never hardens ...........and clean down both faces with thinners to remove oil or old sealent..............

[Pauly]

Just to clear this up.

Is this the loctite RTV? I know it says RTV on the listing but doesn't say it on the packaging.

Loctite 5699 is a Room temperature vulcanizing (RTV) compound so yes this is the stuff.

Silicone sealer is a "moisture" cure sealant

Thats what RTV does, it uses the moisture in the air to vulcanise at room temperature.

Silicon sealant is a solvent based compound that requires the solvent to flash off for it to cure

not sure where you got your information from Sprocket ?

Try looking on the Loctite website, you will find that RTV is not a moisture cure product but silicon sealer is

Happy New Year any way

i've used pro seal aviation gasket sealent for years. it's great stuff, dissolves in oil and fuel and stays slightly wet, handy if you ever strip the engine again as it saves scraping loads of gack off.

For years I used proper gasket sealant. Then a few years back I raced on a sidecar outfit and the Driver who is also a bloody good mechanic and does it for a living rebuilt our engine using decorators caulk as a sealant. Ever since I have used this on loads of occasions with no trouble what so ever. It's loads cheaper than other gasket sealants.

I'm sure that lots of you will have something to say about this but it has always worked for me. Even on a head gasket as a get me home from castle combe!
