I have encounter various vacuum leaks keeping me from being up and running. After removing the blower I pressure tested just the blower and TB plenum. At only 3 lbs of pressure the screw on the TB was just blowing bubbles everwhere. Is there an O ring or seal here that seals this?
Also found the shaft on the bypass just blowing out air as well. It is a real bad leak. I had a junk TB plenum to practice on. As you can see from the picture I destroyed the straight through needle bearing getting it out. The end bearing is enclosed on the end so a small drive punch drove it out easily. Like all of eatons everywhere it has odd ball sized bearings as you see from the picture. The bright spot is there is lots of meat around the bearing when it is installed so I should be able to bore both holes out and get something that is a little more common. Also the depth is quite a bit so I might be able to find a seal that could press in to help seal around the housing if the bearing I pick doesnt have a built in seal. As you see I like to take a lot of pictures of things like this. All the years I have been playing with the car and on this forums I never have once seen pictures of the bypass shaft and its bearings. If over the years the seals dry up how many of you guys have a decent leak in this area?. Do the new MPXs have new bearings with seals in
them? Just food for thought
