Uh-huh...haven't updated this in a while.
In the mean time, harmonic balancer went to hell causing timing to slip, first a bit, so I saw it as a pump issue, and then it slipped completely and consequently pistons slammed into the valves, resulting in 12 destroyed valves and a never-seen-before DOHC head on a D24TIC.
Pictures:
"Stains" on the pistons were actually only from all the burned fuel, and in the aftermath score was: Forged pistons vs. Valves 1:0.
Kids, do not try building a DOHC head this way at home!
So, after two weeks off the road, sourcing parts, almost-new cam from a wrecked VW LT with super-low mileage, new valves, valve seats - complete head job, another Glasser MLS head gasket, etc, we're back on the road.
Fixing the A/C and installing another, electric, fan in front of the A/C radiator:
(The fan used was engine fan from my parts car)
