Hey guys!

2004 E55
THE FOLLOWING PARTS ARE NEW:
Spark Plugs
Wires and Coil Packs
Injectors

I did a smoke test and found smoke leaking from under the supercharger, rear passenger side.

any idea what is could be?

thanks

 

Vacuum hose plugs in back there. Easily dislodged.

The guy with the red cap is how you check and fill auto trans fluid.

 

red cap is to check oil level with dip stick, no? And the vacuum line I think you’re referring to plugs in on the opposite side

 

First statement correct.
Second statement erroneous. That is for checking engine oil level with aftermarket dipstick.
Transmission fill tube located behind throttle body.

Throttle body has two lines connecting to the valve cover vents to pull oil vapors into the intake.



Motor oil check tube has the arrow pointing to it left center. Transmission fill tube lower left partially hidden behind the hoist point.


Lines from throttle body to valve covers attach at the points indicated in the circles below.


Easiest to check by removing the two surge tanks. Have a piece of cardboard and punch holes in which to place the bolts as you remove them; the bolts are various lengths. Replacement gaskets are inexpensive.

 

Thanks @bbirdwell for the clarification, as always you are one of the many wise ones on this forum.

 

My mistake... E-55 got sold ten years ago. Loved that car.

 

@al00sh
Also take a look at the connection between the Y-tube exhaust of the supercharger where it feeds into the passenger-side surge tank. It is a very heavy duty sleeve connecting the two but always possible it was not fitted correctly as it is in a PITA location.
I'm referring to the outlet just to the left of the MAF sensor in the photo below.

 

Yeah gonna have to pull the supercharger and have a look thank you for the visual sir

 

Just pull the surge tanks before anything else. Amazing how much room you will have with the surge tanks removed. Next item would be to remove the throttle body and swing it out of the way without attempting to disconnect the harness. Be advised on my car, both of the sacrificial cables were epoxied into the connector on the throttle body and the supercharger bypass valve. Do not attempt to remove from either throttle body or bypass valve body; the distant end of the sacrificial cable plugs into the engine harness under the supercharger and can be disconnected there (once you can reach them). The bottom two screws of the throttle body hold a metal plate in place that keeps the rubber lines firmly attached to the throttle body seen in the first photo.
If you do plan to ever remove the supercharger, I really recommend an engine hoist. That SOB is heavy...

 

Disregard this post.
