No, sounds like I'm sucking air at cylinders 2 and 5 AGAIN. We've been down this path before. That's why I sealed in bed of silicone last time I had intake off. Am not real impressed with these neoprene or whatever O rings. Don't think they can handle the heat. This time will buy a set of industrial teflon. FWIW, am wondering if acetone in carb cleaner melted silicone as I tested leaks. Cylinders 2 and 5 were air tight last fall. With all due respects to your wonderful European buzzy engine designers, would it have killed them to use a few more bolts to hold intake down? Ford saw fit to use no fewer than 10. And here's a stroke of genius -- they ran them whole length of heads, not just in the corners! IMHO are just asking for trouble bolting an aluminum manifold this way. Am guesstimating my intake is slightly warped. Will put a straight edge on it tomorrow. THIS is why I like my 460's. Takes a little while to de-emission them and rip all that vacuum crap off, but once you're done, you're done. An oil change here or there, AND THAT'S IT. Period. Am not opposed to replacing CPR, but need Darren to look up Renault output pressure vs units DeLo vendors are selling. No sense buying the wrong one. As if I don't have 1001 OTHER things to do...
