[QUOTE="redbullet, post: 438059, member: 19555"] To find leaks I did the following with the engine off: put end of shop vacuum in tail pipe with blowing mode on, duct tape for tight seal, spray various points that can leak on manifold with soapy water, bubbles indicate a leak. Tighten anything that leaks. Have you tightened all manifold bolts to spec? Valve cover bolts? Oil fill cap tight/sealing properly? [/QUOTE]
