You need to do a charge pressure test to confirm the air leak and then a smoke test to locate it, but its likely got a snapped inlet manifold bolt.
If it is a snapped bolt.....would i have to replace the full inlet manifold......if so do you know how much it can cost???

Yes, the bolts are captive in the manifold and have since been modified.

Its roughly a £1000 job at an indie.

Do the bolts break in the engine block and need to be drilled out.......or are they pretty easy to remove and are snapped in the manifold itself......seem like an expensive dooo.....
