Had the head off my 2.5 mn & after reinstalling I now have a whistle sound from the turbo as revs increased. I didn't remove exhaust manifold at all & I have checked the turbo to manifold & exhaust connections. Vacuum lines seem ok & also the boost air hose clamp is tight. Would appreciate any suggestions on what else I could check
