Well, the project van is running, the engine probably only has 30min
or so on it, enough for the paint to start burning off of the S&S exhaust
and for me to fill the cooling system and get the engine tuned up.
I'm gonna go up this weekend and put it though a break-in cycle to
get the rings seated, but until then I'm having a little niggling problem.
I wired a VDO oil pressure gauge up with the dual sender and the
extension hose. I wasn't entirely clear on which post the gauge was to
be wired and which kept the idiot light wire. They are labeled S and WK
(I'm pretty sure of that, but the van is 50 miles away and I didn't write
it down). I wired the gauge to the S terminal and the WK to the idiot
light.
The gauge is reading about what I'd expect, about 60lbs cold at idle
(10W30, new bottom end) settling down to the 20-30 range.
The idiot light, unfortunately is a bit weird. It doesn't give its
normal test routine, blinking continuously, but not buzzing with the
ignition on and the engine off. It goes off when I start the engine, but
comes back on and buzzes a few minutes after I start the engine and rev
it. (It doesn't come on if I keep the engine at or near idle) All the
time, the gauge reads plenty of oil pressure.
Any ideas?
