I used a crimp connecter, not the ones that came with the w/m kit. It was on there good. I will disconnect it today and find out if that changes anything. And yes I do have fuel in the tank. Umm.... Oh I will also check the fuses. Oh and yes, that hose is number 15 in that picture. It looks like it's been cut for a long time (there is dirt and crap inside it) so I don't think it's anything.

OK so just to make it easier on everyone here is a list of everything I have tried with the outcome of each test:

1. Checked W/M check valve - clean, still having misfire problems.
2. Completely disconnected the W/M kit - still having misfire problems.
3. Switched Coilpacks around - still have misfire problems on same cylinders. Did not follow coilpacks.
4. Pulled and tested the ICM's - both are good (according to the test) and still have misfire problems.
5. Swapped ICM's - still misfiring on same cylinders
6. Swapped spark plugs around to see if misfires follow them - no go, misfires still on same cylinders as before.
7. Replaced all the spark plugs with new ones - still having misfires on same cylinders
8. Pressure test - could not find anything leaking. Still having misfires.
9. Visually inspected all all the vac lines - could not find anything. Still misfires.

I am pretty sure thats it.

Here is my list of what I am going to try again today when I get off work:

1. Disconnect the wire from the MAP sensor that goes to the W/M kit and see what happens.
2. Compression Test (If this fails I will be ROYALLY PISSED!!!!!)
3. Spray down the engine with soapy water and re-try the pressure test.
4. Check all fuses that have to do with fueling... I will probably check them all anyways.
5. Throw a freaking wrench.
6. Have it towed to a buddies shop and see if a fresh set of eyes can find anything.

If anyone has any other ideas of stuff for me to try please please please LMK. I am getting desperate.

nvm i read wrong...

 

Ha! I saw the original message. Quick move before the flaming started.

 

PROBLEM FOUND... NOT SO GOOD!

Just got my car towed back to my house from Chris's shop. The diagnoses is not good. We tested the ignition system and everything is good there. We then decided to do the compression test. This did not turn out so well. 3 of the 6 cylinders are running 175 for compression. 2 of them were around 155-160 and then cylinder number 3 (the one that was having the most misfires) had a big fat 0. Thats right, a 0. We looked into it further and concluded that I indeed have a blown head gasket and also have fried the piston rings. Woopty Freaken Do.

SO now I get to rebuild it.

What do you think? Should I leave the engine in the car to do it or pull it out? What do you think caused this? My first guess is the chip had a bad tune or something. I HIGHLY doubt that the W/M kit did this in just a matter of 45 min of the car running.

Josh

 

That really sucks! Besides adding the water, did you do anything else, such as advance the timing or up the boost? I, too, don't believe the w/m alone would cause you to blow a head gasket.

 

Nope, I used the pre-mixed stuff from Devils own. I did not even have enough time to tune it at all for the W/M kit. All I did was install it and ran a few intake temp logs I will post those in a bit to see what you think IAT wise before the W/M kit was activated. I am wondering if it was a bad tune or something. Maybe to much boost? I was spiking 17 and holding 15 with the GIAC-X file. Maybe I was running super lean or something because of it.

If you find a hole in the piston, then you did go lean, but due to a fueling problem with that specific cylinder. If the fuel injector clogged or failed, you could have a very lean cylinder 3. But if the piston is intact, then the engine should handle a 17 psi spike. Or the 2.7T is the weakest Audi engine I've seen. If anything, the w/m should have protected the engine instead of causing the problem.

 

I don't think it's a fuel injector problem. The spark plug was REALLY wet when we pulled it out and it smelled like gas.

Josh

 

The head(s) could of lifted and that would of blown the gasket. Since you have 0 compression, there has to be damaged valves also. Kind of sucks you havent had the car to long. I do think posting repair advace in this forum isnt going to get you much in the way of good info.
