Finally, finally getting around to beginning a little work on this thing. I thought I'd get some time during one of the 27 goddam rainy days we've had so far this year to work inside the van doing the compression test. During that time the battery ran down, of course, so I was unable to crank the van sufficiently long to get all the cylinders done adequately and I did it cold. So, I went out and bought new plugs while the battery is on a charger and will try again tomorrow.
Findings so far (see pix), the left bank (cylinders 1, 3, 5 and 7) are over 100 PSI, although the variation between cylinders is out of spec, while the right side (cylinders 2, 4, 6 and 8) are low-low-low. I had pulled all the plugs, worried that there might be water in some and wanting to avoid hydraulic lock, so when I cranked it over initially water spewed out of #6 and went all over the passenger side door panel. I would have thought that was the only problem but for the two cylinders reading 0 PSI. I'll retest tomorrow with the new plugs and after I get the engine warmed up, but even if the numbers improve I've got my work cut out for me.
Question: Would I be better off leaving the plug wire off #6 (the suspected spewing cylinder) in order to keep the smoke/steam down or should I let the plug fire to warm that cylinder up as much as I can? Thanks!
Error loading pix, so I'll keep trying. Meanwhile,
#1 - 150 PSI
#2 - 0 PSI
#3 - 130 PSI
#4 - 0 PSI
#5 - 110 PSI
#6 - 30 PSI
#7 - 110 PSI
#8 - 70 PSI
