i just sprayed soem copper grease on my exhaust valves.
its good no? next time i will put some lithium grease. i never lubricated these before.-

 

Are you talking about the muffler bypass valves? I imagine anything you apply for lubrication will just burn/blow/wash off. The shaft of the valve is in a bushing in the valve body. Those typically aren't meant to have additional lubrication.

 

Yes it might be then. Here it is. Thanks for replying.

do you know how to reach the exhaust
valves then? With lithium grease is ok?

 

Copper grease will burn off the first time you get the car up to operating temperature.
I don't even want to imagine the huge, foul smelling cloud of smoke that it will produce.

 

Well thank you. I cleaned it up.
i m good to clean my rear bumper now from.underneath....

 

The grease in the copper grease will burn off, leaving the copper. The copper will keep the steel parts from galling. It is exactly what I would use on the rods & cranks (though I wouldn't spray any into the vacuum housing where the rod goes in. If any of that is stiff, a bit of red rubber grease would probably be more appropriate there.
