  1. Before I put a used supercharger in my 99 Millenia S, it smoked on startup, AND after idle for 2 minutes or more. I found what I believe to be a good supercharger and put it in. This solved the smoke after idle, but not smoke on startup (to my utter dismay). I got the whole homeowners association on my case for that, so I'm not going to run out and take off the heads. Looking back at the mechanics notes from the previous owner, they said:

     

    Performed inspection, found valve seals leaking. Customer informed engine needs to be torn down for inspection and cylinder heads sent out for inspection. Customer informed repairs might exceed value of the car.

     

    let me say the car runs like showroom after the startup smoke goes away. When I inspect the CAC, I find oil throughout. My question is, if the valve seals leak oil, how would it end up in the CAC? Is this some sort of Miller Cycle magic?

  2. Solved the 1540 code problem. It was a disconnected vacuum hose going to one of the solenoids above the right bank spark plugs. I couldn't see it until I took the CAC assembly off. Shored up some other vacuum leaks while I was at it. Same solution as someone else had. Bottom line: if you work on your S and then get a 1540 code, check the vacuum lines near the solenoids.

  3. In my manual for a 99 Millenia S - "Air Intake System" - it has this installation note about the air coolers. I am trying to solve this P1540 code problem (I've seen the other posts), and it talks about orienting the "air hose" (btwn cooler and alum. CAC) clamps at a precise angle. I can't figure out what they mean. Its marked 60 and 125 degrees for A,B, and C clamps etc. I remember moving the clamps so they were easier to get to. I rotated them from facing the rear of the car to sticking up straight. Is this important? Could this cause a 1540 code?
