    L series - Positive crank case pressure, too much.

    OK I did some tests

     

     

    I can hold the throttle at 4,000 RPM for example and no smoke.

    When I let off and let the car widn back down to idle and then quickly add gas it shoots a CLOUD of smoke.

     

    SOO.. narrowing it down.. smoke is only during deceleration and/or when the engine is winding down.

     

    Does this point out any possibilites?!

     

    BTW i purchased a new valve spring compressor so I'll change them tomarrow with the head on. but I was hoping my description might help.

     

    I think Garrett is on to the right idea.. on decel or engine wind down.. the vacuum goes to about 20" in. hg. while idle is 10" in hg. seems like the increased vacuum is pulling in oil from maybe the valve stem seals!?

    MS vs SDS, pros and cons?

    Welcome to the board himself.

     

    This post should belong in the Engine Components and the "Other EMS" or "Megasquirt" forum..

     

    Both MS and SDS is standalone so it replaces the cars ECU.

     

    MS is cheap SDS is a bit steeper in price.

     

    I am using Megasquirt on my 280Z with a Holset turbo and I have been running 18psi for sometime now. Tuning is fun and easy..

     

    alot of people are running SDS and absolutly love it and its exactly what SDS stands for. SIMPLE. it can be installed and running in a day, while Megasquirt takes some fine tuning and getting it perfect.

     

    I vote Megasquirt. but SDS vote SDS.

    I will be using a exterior caulking/sealant with some "extreme temperature" ducting tape. The tape is aluminum with a strong adhesive and should withstand cold and hot temperatures and is waterproof!

     

    Everything I am using is from Home Depot.. since I work there I have alot of spare time to wonder around and look at the product haha

     

    So far this has cost me $22. $12 for a 4x8 sheet of sheet metal

    (Home Depot offers 3 types. Galvanized in the plumbing/ducting aisle. The steel is 26 guage for $11. Steel in the hardware department which is way overpriced. $18 and its 22 guage. The third type is 22/24 guage steel in the gutter/roofing aisle used for flashing. This was $12 and much thicker than the galvanized metal in plumbing)

     

    I used 3/16 aluminum rivets and washers =)

    Well after looking at TitaniumZ's front end mod with decreasing the opening to the radiator and reading the data on the Aerodynamics data chart..

     

    I decided to block off the upper grill from the bumper line to the hood.. and I also blocked off the sides of the grill so no air is wasted in the monster opening of the Z's mouth.

     

    I just welded on some sheet metal from Home Depot behind my grill..

    and added a piece of sheet metal from the air dam to the radiator support.. and an upper piece of sheet metal from the grill, across the intercooler and to the radiator.

     

    I am just experimenting with different things right now.. yes its ugly but Function over Form.
