In my engine theory class the teacher mention some type of teflon patch they would put onto the skirt of a piston in a piston engine. Could the same be done to a rotor housing?


::edit i found the page its a moly coating but looks like teflon

 

I heard of it being done on a rotor housing. There was a thread about it a long time ago. Big debate as to whether it was worth the money/effort. There wasn't much info about it being widely used, or how reliable it is.

 

i think ppl in that thread said it was cheaper and more reliable just to buy a new housing

 

<- Is interested in this thing.

Got a link to the page?
