RayJay Turbocharger Checkvalve
« on: August 30, 2018, 10:59:11 AM »
I have the RayJay Turbochargers on my helio....anybody out there have them?

I like them... work great...I live in Reno and they really help out when using at altitude...I live at 4500 ft...

One issue- if the plane sits more than a few weeks oil leaks past the turbo chargers and drips down the exhaust pipes into a pan I have under the engine...I have heard that their are check valves available that prevent this (and may have been part of a later turbo STC)....Any Info would be appreciated....

Tree top,
I have a question?, I was looking in my 337 files and I noticed they show you have a Roto-Master Turbo Charger (STC SE124SO) is that turbocharger the same as the Rayjay/Riley or is it a replacement?

I don't see anything in them on check valves so your question is one for someone that actually has knowledge about turbochargers and that isn't me.
