Greetings,
Well, I spent the morning
welding on a small 1/8" plate to each of the evap cores. In those, I
drilled and tapped a 1/8" NPT hole, and installed a petcock. Man, what a
difference! I filled the engine just like yesterday, then opened the
valves- wooooosh goes the air. I added about another gallon until the
water came out of the valves.
Once filled, I tried to run
the EWP (JB welded and not leaking), but it was still not primed. There's
a bit of a loop in the hose that feeds the EWP, so I cracked open the fitting to
the inlet of the EWP, and out came the air. Once that was done, the EWP
runs fine. The first thing you notice is how much you hear the water
flowing through the cores. It does sound like the fire hose that Tracy
refers to, and it's something you never get to hear with the normal pump,
because the engine drowns it out. Just from the sound, I have no doubt
that the EWP is flowing plenty of water past the stationary mechanical pump, so
I'm certain that it will make a dandy backup pump in the case of a belt
failure.
There's one oil leak that I
know of, and that's on a cover plate that I made for the front cover. I
still need to remove an oil line, and fill the filter and cooler to see if
they're leaking, and also prepare for a first rev-2 start attempt. This
will all happen tomorrow.
Cheers,
Rusty (my Lycoming RV-3
buddy made a low pass at my airport, so the gauntlet has been officially thrown
down)
