Hey blackhand, nope haven't filled the engines up yet. I'm waiting for my CanKeys to arrive.
The GTD-350 will be filled this coming weekend, although it's not quite ready for a full run yet (need to do some welding work on the exhaust deflectors) so it'll just be an oil pressure test on the starter.
The Williams needs some hydraulic work and I sheared a bolt on the rear turbine housing on Sunday, so that's probably a month and a lot of swearing before I can refill that one.
I've taken your advice (and that of the people who PM'd me!) to not change the oil on the Williams, so it will get BPTO 2380 again when I do fill it.
If you're interested what I'm up to I have all of my engine work online at
