Vaccum Leak

I have WB holden Ute with a Blue 202 which squeals when decelerating from medium speeds(80-140). I'm sure its the vaccum, i was just wondering if anyone had worked with these systems and could direct me to the problem.

The most common vacuum leak is from the inlet manifold. Do a leak test by pouring water over the inlet mounting surfaces while the car is running. If it runs worse then your problem is there. Make sure you have both manifolds "still joined" machined before using new gaskets.kik
