Which gasket goo

mate if I was using a gasket then just that aviation gasket goo is what I would use I wont use silicone any more I have had to many problems with it getting forced out and then it wont break down like gasket goo and blend in with oil it just breaks off and floats around and blocks stuff

My vote is for the non-hardening aviation cement. Silicone has to be used very carefully and very sparingly.
A bloke here had three pistons seize in his 3406 in a row, and couldn't find the problem - until they checked the piston oil spray jet and found it blocked with a wad of loose silicone from surplus silicone that had squeezed out of a gasket join.

I'm with everyone else here. 😊 (Makes a nice change doesn't it. 😊 )
The non hardening aviation gasket goo is the way to go. My personal preference is for the Permatex No3. I have been using it since I was a first year apprentice, and I have bottles of the stuff around here, everywhere. I don't know many good tradesmen that don't use it. Hylomar is another good one, but I believe the Permatex is better. Professionally, I stipulate it quite regularly.

I have started to use anaerobic cure sealants on machined surfaces used without gaskets. They must be clean and dry, but the stuff is a joy to work with compared to RTV silicone. No lumps, plugged up tubes or worst the whole tube has cured after a single use and you must make a trip to town to get more!

Permatex makes one, not sure what the number is, but it is similar to what JD and CASE/IH are using in factory assemblies.

Silicone has its place, but the anaerobic cure liquids are good products when used in the correct situations. I assume that the excess which squeezes out of the joint and does not cure will be removed by the oil or other fluid that is being retained. Haven't seen any problems in powershift transmissions and hydraulic systems where I have used it to install final drives etc.

Why did Cat stop making/supplying the product we called Cat red
Found that very good in the right places

Good morning,
I maybe wrong, but I think chemtool incorpated and their division metalcote used to make a lot of sealants for Cat.

Does anyone have any experience of dealing with this company?

I don't know, but I wish they'd start again! probably whatever ingredient made it work has been banned by the EPA...
