Does anyone know what kind of grease I need to use for a blow off valve? Thanks

 

i didnt know that we had to grease up our bovs

 

My GFB sticks sometimes when it gets real cold. A shot of WD-40 onto the BOV piston through the vent port when the car is off usually clears it up for a few weeks. Only happens in the winter when it is really cold though.

 

never had my BOV stick...but i could see it happening in somewhere real cold...

 

I would use a good, light synthetic grease sparingly...a little bit spread well all over....oil doesn't have the same lubricating properties as grease and won't last nearly as long.
WD-40 is a poor lubricant in any case. LPS is MUCH better.
