I recently installed new 24# fuel injectors to make way for the Procharger I just got. Worked fine for about a week(although way rich) then it started to smoke white(maybe really light blue, its hard to tell) smoke continuously and its thick. It gets thicker the more throttle is applied. I read in here that it should maintain pressure for around 2 minutes. According to my FP guage it goes from 50psi to 0 in around 4 seconds. If this is wrong, could you tell me why, and if it could relate to the car's smoking problem. As you can imagine I need to get this problem diagnosed and fixed before I go completely insane from having a beautiful new supercharger system sitting in my living room. The engine is a new LO5 from Scoggin Dickey with appx 5k miles on it.

 

Blue is Oil, White is either coolant or Water boiling.

Black is Overly Rich.

As for your Fuel pressure dropping so fast, something is obviously wrong.

I don't think the injectors COULD leak that fast.

Probrably the FPR thats ****ed up. Or Possibly the pump.

You say its been running really rich ( and obviously, with the stock PROM and 24# injectors) But how do you know ?

 

Sounds like a blown Head gasket to me

 

Well the reason I know its rich other than 50psi with 24 pound/hr injectors is it smells like fuel. I checked compression on the cyls that my headers allow and it was like 182 even for all of them(only could check four). From what I can tell there is no water in the oil and no loss of water that I can see(although its all just testing at idle since I cant drive it with all the smoke/steam/whatever. The engine doesnt stumble or anything. I would be happy if it were only a headgasket or leak somewhere or something, thats just a weekend job, but I dont want to rip my top end off without knowing what it is first. Forgive my ignorance but could the cat have taken care of the smoke for the week it ran, then it just give out? I didnt drive it for about a week, then did some maintenence (new heater control valve, power steering flush fill, moved a couple wires from sensors and put shielding around them, put synthetic in etc...) the smoking started then. I read on one of the tech articles that if the O2 wire grounds it fries, if thats the case my O2 is fried, although it still generates resonable readings on the AF meter. I did kindof a nono in putting the runners back in, I used the same gaskets.

 

Well, In any Case if its white, its coolant related.

So SOmehow coolant is getting in there.

Bad intake gasket, Bad head gasket, Cracked block or Cracked head are your culprits there.

Look for pressure buildup in the radiator when cold, that will point you at a headgasket.

 

Just how blue is blue smoke? Cause it pretty much looks white, but if I wanted to see blue I could.

 

coolant has a very distiinct SWEET smell to it and oil has a very distinct bad smell to it, almost everyone has smelt burnt oil on the headers. another way to check your symptoms.

 

Yeah thats the confusing part. It looks like water but smells like gas/oil. The gas smell is too overpowering to rule anything out though.

 

When I blew a head gasket on my car, it smoked like that, it was white but was tinted blue. It happened right after I installed my SLP headers. It smoked worse and worse until it hydro-locked.

Was a leaking fuel injector.
