1995 BMW 540i Q&A
1995 BMW 540i Question: intake manifold?
see if your local auto parts store has a engine coolent pressure tester, in their loaner tool program. pump up the system to the pressure rated on your radiator cap, then look for leaks. This will push out coolent you won't find in other ways. - torque wrench
It is probably the valley pan gasket. Just did mine. So bad news is you have to take off intake and might as well do water pump while you are in there. I would also check the condition of your timing chan cover as mine were like hrad brittle plastic. They are on the front of the engine below vavle covers. I did it myself. Just need to take time and don't overtorque on reassembly. You can leave water pump and take off the coolant line bracket on back of engine. great time also to replace back heater hoses.

Engine oil leaks commonly develop from both valve cover gaskets, intake manifold, and PCV plate after about 60,000 miles.
Already replaced the gasket and the mechanic indicates that the intake manifold is cracked.
I just need to find out he pounds to which I have to tighten the bolts for the intake. My question is regarding the intake bolts. How many pounds do the intake bolts have to be when installing them?
I can't find the heater hoses on first glance. Is that where they are?
my 540i is running rough,shifting rough,exhaust white smoke,and smells like fuel mixture is too rich
