Gasoline in turbo.....
My car was running peachy all of last week besides idle fluctuations, but with a sudden onset of really bad fuel economy. I installed a test pipe that same week, so I attributed the oil consumption from an off AFR reading. Tunerstudio also leaned the hell out of map that week also, even though a leak would have made the LC-1 read leaner.
So today I finally had time to recheck all the couplers etc and I noticed a white smoke from my mani/turbo area. Thinking it was just a leak from having really bad engine mounts (just ordered some while I took a break), I came back to tighten up those nuts a bit and started her up, but behold.... gurgling, wet, GASOLINE was leaking out of that area where it was once smoking.
I've been careful as my car has only been boosting the last 2 weeks or so. No coolant is leaking and there's no oil leak. What should I do next? Compression check?

But isn't it impossible for gas to get over there? All the gas lines are on the passenger side of the car, and the fuel rail is on the intake manifold. There are no gas conduits on the exhaust side of the car.

The car was running fine. It was only on jackstands because I was trying to find a leak somewhere. What am I looking for in terms of injectors? I got some 46ccs I was about to put in soon. I just replaced the spark wire and spark plugs less than 1k ago.

What did you do with the O2 sensors after you put the "test Pipe" in?

MS1...no factory ECU to be pissed off about O2 sensors, I hope..
Everything cool with orings, spacers, etc. on injectors? Nothing stuck open?

I did pull the injectors last week, but put them back in with no visible leak in the fuel rail. Could it be a wiring issue, because I had to rewire the two wires back to each injector connector (don't ask). I think we got the culprit....

If everything was OK before, double check the last thing that was f*cked with...ask me how I know...

Injector #3 was loose. I'll redo the wiring when my new injectors get here. Was I too rough when screwing around with the injectors, or can a wiring problem cause it to be stuck open? Pray it will be alright.....thanks all!

Someone correct me if I'm wrong, but if said retarded wiring job had an injector line held low as in grounded, instead of switched ground, it could hold the injector open resulting in a "stuck open" event...or I'm the 'tard. Oh, we aren't supposed to use the Rohm Emmanuel term "retarded" - perhaps electronically challenged? Or in my case, vodkically challenged?
