hi new to the forum
i recently bought a copper s turbo
having pulled the engine to do the clutch turbo and timing chain i now have a massive vacuum which can be felt on the oil cap, i have a suspicion its something to do with the manifold pipe at the rear of the valve cover, i cleaned out the soot carbon at the valves when i had the engine on the bench,
Help please !
