OK here I go again, thought the problem was gone but I was wrong. Heres what is going on. Its a 2.0 with a mild cam and 40 IDFs. Carbs have f11 emulsion tubes,200 air correction,32 vents, 125 mains and 55 idles. When the car is cold it runs great pulls hard and no smoke, when the car gets up to temp after some driving it begans to put out some nice white smoke. It does it the most when you first give it gas, it smokes some at idle and is ok when the car is going. The smoke smells rich or maybe it is very lean. Here is what I know. I check the fuel pressure and it is at 3 psi, been through the carbs and rebuilt them. They tuned to best lean idle with problem and all the carbs are flowing equally. I added a oil breather box. Set timimg to 27 degrees. Put new plugs in also.
Will a car running very lean smoke and how does it look compared to running rich? The smoke from my car smells very bad and it gives me a headache if I dont get some fresh air. I am just about at my wits end with this, I put the new 2.0 this summer and I just cant get it to work right, its hard to be cool in nice 914 that looks like a steam train. I talked with a friend tonight that said it sounds like it leaning out when it gets warm. Could that be my problem? Thanks |

I had just add a oil breather box to the engine. Someone had filled in he ports on the heads so I opened them up and ran the hoses to the new breather box, along with the hose from the crackcase vent. I hoped that would fix the problem but it still did the same thing as before. (IMG:style_emoticons/default/headbang.gif) THe heads where just rebuilt by some dude in Texas so I hope the valve stem seals are not bad already.
Could running very lean make white smoke too? Maybe I should check the radiator to see if its low on water. Hey thats it... (IMG:style_emoticons/default/poke.gif) |
