| probably sump gasket. it is a liquid gasket with a rubber strip at each end under the crank. I believe they often go at the rubbers.
I have just done mine with hylomar universal blue, appears to be bang on.
ok for the boost problem check that the metal coil is still inside the rubber hose between the maf and turbo, unless you have hard pipes?
other than that try vacum hoses I guess.
cheers
