hello..

Loctite 514 eliminator - hard hi temp : Is this same/similar to Yamabond ?

Where do you use these ?
Loctite 598 black xtremeflex to 260º
Loctite 5926 Blue silicone!!!!!

Why not just use one of them...is my question ? They are very similar.

regards,
henri

I have never seem Yamabond, and I no longer use 514 or 598 but they do work.

I use 5926 exclusively for all motor joints including those that require a gasket; I do not use gaskets at all except for the chain tensioner - and of course the cylinder foot and head.
bare joints:
crankcase and camshaft cover
gaskets
both side covers, starter gear cover.
Those with O-ring obviously use ther O-ring, but I have once put the waterpump cover on without an O-ring, using this stuff and filling the O-ring groove entirely.
Works fine and forms as it were the O-ring.
I have used the 5920 Hi-Temp stuff for plain soft copper head gaskets. While these work fine, they are critical and I do not recommend their use. They are NOT an out-of-the-box solution. I get them from Lany at when I do use them.

Very good to know, I'll put that to good use.....any reason to use the stock
headgasket when you can get a copper one ?

like I said, copper gaskets are not ready-to-use-out-of-the-box. Their use must be understood, learned and this is, at least potentially, an initial source of headaches and problems.
I would definitely stick with OEM for stock bore and brand-name (e.g.Cometic) head gaskets for overbores. Even I do that.
