Yes I know the oil in the intake is a common issue. Normally you see it more often in turbo'd or supercharged motors because of the increased pressures inside the motor. I had driven it hard twice once while towing a trailer. It was over a quart low after the tow!!!
No, I have not measured the gaps yet but just by looking at them you can tell the gaps are way off. Like I said before I felt a slight miss when the engine was started first thing in the morning but didn't seem to affect anything else. I noticed my combined MPG falling down to 17.3 though. Also one time I was flooring it to pass a car and the vehicle actually cut out for a second. This is when I thought it was time for plugs and indeed it was :beer:
No, sorry I didn't take any pictures. I was in such a hurry that I didn't have the camera handy. It really wasn't all that bad once I had all the insulation off. The back 2 10mm bolts that held this insulation to the intake were probably the worst ones to get at. 2nd to that was getting the intake back on with these super long bolts (about 7" long). There were 4 of these that went through the center of the intake. The front two you could pull all the way out. The back 2 hit the cowl so when putting things together, you have to have the back 2 bolts sort of already in the back holes while positioning the intake back on. There's only about 1/2" of play when doing this and the back intake gasket can get pulled off it's area it needs to be. Extreme care has to be had when putting the intake back on because of this.
Everything else was pretty easy. Just snapping electrical connectors and such. I did remove the crank case tube, intake, and also the fuel vapor line to make it easier. You will need to have a decent set of extensions and swivels to reach some of the bolts. Glad I did it and glad that I got it done. It ran so much smoother. Drove about 50 miles combined driving and the DLC showed an average of 20.2MPG :binky:
