Out of all the engine bearings I have installed/replaced I had never thought of this.
Would useing a small amout of dry teflon spary on engine bearings help protect them on the first start up?
Or how about coating flat tappet cams with it?
I thought this would be best for mostly for diesel engines that I am just replacing the bearings and not doing any thing to the crank or cam surfaces just to protect the bearings untill the oil can start flowing.

 

Don't you typically lube them before assembly? Even if you're not doing anything to the journals, they share a surface with the bearings... Personally, I would prefer to use something with some 'substance' to it.

 

I was thinking that a shot of Dry Moly Lube wouldn't hurt things.

 

Get the red assy lube or Lubraplate white lube and put plenty on everything. Ya can't go wrong with the right stuff.

 

Stay away from Teflon. The FTC stopped Andy Granatelli for making claims of Teflon improving the perofrmance of motor oils with STP. DuPont refused to sell Teflon to the snake oil peddlers (e.g. Petrolon's Slick 50), because there was evidence the Teflon particles were plugging up the oil filter and the oil pickup screen. Studies by the Dept. of Defense amd BMW indicate that the Teflon additives can do more harm than good. The literature suggests that in order to chemically "bond" Teflon to a metallic surface requires temperatures in excess of 800*F.

 

have also heard bad things about this at low temps. And also heard of teflon not surviving in a high friction enviroment.....I would stay away
