Tks guys for your kinds comments. Bill my intake is the 4 type as the picture of the gasket. I think we should use this as "Sticky" if you asked me, sometimes cars can blind sight us in their "behavior" .
I never forget a 67 Ford Cortina GT I had fitted with a dual OHC from a crashed Lotus Super 7. Every time I turned right on to a steep hill curve the car would die as if starved out of gas.
After extensive mechanical forensics, then, my Dad had the vision to pull the gas tank out, to our surprise someone previous to my ownership had a dropped a small piece of fabric in the tank that would slide with the surge to the gas pick up every time I turned.
Once removed the problem was corrected. But sometimes they will stump you.
Thanks again guys
Lou
