Bryan, Wilkinson,

 I, too, am in
the market for a pre-oiler and have found virtually nothing on my own.
Can you give me any descriptions, sources, and prices?  Thanks.

David ,

I'm over here in the UK , and the last I heard was that pre - oilers
were being STC'd stateside - I will put your original message in my
gliding folder and ask  the engineer at my gliding club , as these would
be the prime candidates for pre - oilers per se.

IIRC it was in essence an hydralic cylinder with a non - return valve  on
the output , and arrangements for retracting the piston and refilling the
cylinder somehow. on startup the oil system is pressurized before the
starter cranks , logically :^)

Easiest way - reverse engineer or find out who makes the STC part - gas
turbines have incorporated  them for years according  to an ex - royal -
navy helo pilot I know ......

happy building  &  flying

Bryan
