I've been chasing down an induction leak, finally identified the source.
I'd posted about what kind of induction system is on my plane. With good help here, it is confirmed that I have a Sky Dynamics cold air induction system. After rooting through all the paperwork that came with this purchase, I found a Sky Dynamics installation instruction sheet. So far, so good.
So earlier today I do the soapy water leak check. The very last place I sprayed, inside bolt on cylinder #4, started bubbling big time.
Ok, time to pull down the intake system and replace the gaskets...yep, I could see gasket edges, even though the SD system has O-Rings. Well....yep, each cylinder had an intake gasket...AND an O-Ring! What the heck? In the pic, you can see where the cyl 4 o-ring was badly pinched, and this was the area of the bubbles (no surprise after seeing this.)
I'd ordered Superior gaskets (thinking that's all I had, based on seeing gasket edges), but now with the O-Rings, my questions are: Why use both? SHOULD you use both? Will a gasket seal properly with that grooved flange but no o-ring in it?
I'm having a LOT of trouble establishing comms with Sky Dynamics. Not very responsive at all; calls and messages-left go unanswered.
Any thoughts here?
