I started it again and toyed with it predictably like a kill switch. what could it be??????? anyone know. thnx. I bet the PCV system is clogged up. The vac system on these engines are supposed to be tight/closed, it will effect the idle when you open part of the system (oil cap). but runs with the oil fill cap on? :picard: Link to comment Share on other sites More sharing options...
Gloyale Posted January 4, 2010 Share Posted January 4, 2010 The engine case is part of the intake system. When you open the cap, you let tons of Un-metered air to enter the intake stream. Engine can't run like that. It's just like pulling one of the PCV tubes out of the intake boot. Very normal. You don't want to add oil with the engine running anyway, it will spit it all back out at you. Link to comment Share on other sites More sharing options...

It's the round thing on top facing towards the front of the car. Can't really miss it. Once you find it, you should be able to follow the wires. Mine does the same thing, so I just installed a vac/boost gauge to make sure it's producing boost and the correct amount of boost, but I am also going to replace mine with a used one, just so the light comes on. Hope that helps Link to comment Share on other sites More sharing options...

But mine is disconnected and I have a standard boost gauge now. The PCV valve is located on the back-drivers side of the intake, you should see a hose connected to it. These can be cleaned, if they arent junked up to bad. But if you replace it, go OEM. Check the hoses for carbon build up also. Link to comment Share on other sites More sharing options...

GeneralDisorder Posted January 10, 2010 Share Posted January 10, 2010 That's stupid. It will foul the oil with acidic blow-by gasses and eat your bearings. If you really want to eliminate the PCV then remove the crankcase from the metered air of the intake. Install a road-draft tube on each valve cover and plug all the lines to the intake.

AWD TURBO! Posted January 10, 2010 Share Posted January 10, 2010 so the vacuum from the intake is not going to work. Link to comment Share on other sites More sharing options...
GeneralDisorder Posted January 10, 2010 Share Posted January 10, 2010 so the vacuum from the intake is not going to work. No - of course not. You are sucking on a dead end. You need positive flow from one valve cover, through the crankcase, and out the other valve cover. You can't just suck on the crankcase - try sucking on a drinking straw while plugging the other end with your finger...... GD Link to comment Share on other sites More sharing options...
