I have four bolts on my intake plenum manifold. One that sits directly on top and three in front. Two bolts on the left in front broke off in the manifold itself but visible. The third it looks like it has a stem or valve inside the bolt itself and is very difficult to remove it is a little bit stripped looks like it would have been 8mm or 5/16 Sae yet it wont budge. How can I get this bolt off?
have the same problem?
