up. If they break anytime soon they will get sucked through the head and down into the block then it will eventually blow the bottom end. Fourth is I have some weird ass sound coming from the head. I believe the valves are
up and get stuck sometimes. I think this because when it happens my exhaust sounds like a damn sti. But for those butterfly flaps it is a known issue but Ford just won't recognize the problem. The Mazda 3 shares the same intake manifold and they had the same issue and they put a tsb and recall out for it. Ford just wants to make more money off us. They want me to replace the whole manifold assembly for $208 which is stupid because euro 1 supply has the replacement flaps for $111 shipped.
I pull the manifold off & remove the flaps altogether, & fill the hole on the end w/ part of the shaft end cut down.
