Intake Leak

could it be the valve covers or valve cover gaskets preventing the intake to sit down in its place? judging by the pictures, its awfully close. it happened to me and i had to grind the top of the intake just under the valve covers for clearance.
also, check for cracks on the intake. good luck.

Thanks for the input, but there is just enough clearance under the covers. I don't think there's any cracks as I've had this intake for 5 or 6 years and it's been fine. I drove my car 400 miles last year and never had a leak. The problem started when I had the block decked .015 last winter and this summer it started leaking. So it's looks like an angle issue to me, it might only be a few degrees off as it did last 100 miles before it started leaking the last time I replaced the gasket in September.
