Well, car developed a miss - was very slight during warm up after the initial supercharger install. Drove it to work and had a definite miss at warm idle (at 550 mile point). Bummer.
Pulled the plugs and all looked very similar with #1 a bit tanner. Figured I damaged a plug wire or cracked a plug so ordered a complete set of both. Got them after 1.5 weeks and installed.
Car had a bit of an issue cranking...then fired...still with a miss at idle. Did a quick drive - HPTuners showing #1 misfire (yet no CE Light?). No issue at WOT.
Pulled #1 and 3 plug...still tanner than the other. Swapped coils between the two...still #1 misfire. So must be an injector (brand new GM though). I also realized the supercharger cooling system was near empty...hmm.
Pulled the supercharger and got an eyeful of water in #1 port. Bummer.
And the cooling brick dampness:
Appeared to be caused by a damaged o-ring:
Crossing fingers my failure to install the o-ring properly didn't hydraulic the #1 cylinder to failure.
Anyone know the part number of the blue culprit?
