Head work on a 79 gs

[Guest]

Hello all,

just a quick question: In my manual when installing the valves it asks for molybdenum disulfide lubricant for the stems. Im not entire sure what this is; grease? powder? Do I even need this? Valves are original but reconditioned, valve seals are new and were oiled when installed.

Can anyone point me in the right direction?

Thank you

Assembly lube has moly in it. Hit up your local auto parts store for a tube.

The book also notes that no STP can be used. I was under the assumption that most assembly lube contains this.

Im assuming the lube that is required is just for initial startup. Anything will burn off fairly quickly when the valves heat up.

I have always used the oil the engine is going to start with on the valve stems & seals and have no issues.

Third that Ray..I just oil the snot out of everything and pull the plug wire when first rolling it over. Crank for a few seconds..pause a second or so..crank it again and let the oil pump circulate oil well. Then go for the full on firing off.

Thanks all for the advice.

I wonder why the moly requirement in the book still. Suzuki doesn't seem to be a manufacturer who does unnecessary steps...

If you want to follow the book get the assembly lube with moly. Use it sparingly. Not sure why you are connecting STP with assembly lube.
