Circulate Oil in Engine During Build?
I've about completed the FWF on my CH750/Jabiru 3300. It's only been about 6 weeks since I picked up the engine from Jabiru USA and took it out its crate and shrink-wrap.
Even though the fuselage/tail/controls/flaperons/slats are completed and the wings are about 90%, I realistically think it will be late Spring before I actually will finish what with paint and that other "90% finished - 90% to go" that usually comes up.
As I understand it, the engine presently has inhibiting oil for storage in it. Would I be best off to simply leave it alone for the next few months and just follow Jabiru's procedures for prepping the engine for first start at that time, OR, would it be adviseable to go ahead and fill the cooler and engine with the correct oil, and take a plug on each cylinder out and spin it up to get oil pressure - then maybe turn it over briefly ever few weeks after that?
I KNOW not to actually start the engine without a prop to prevent engine damage (with wings not on, there's no fuel supply, anyway!) But, I didn't know if the wear and tear of cranking it cold and circulating the oil would accomplish anything in the way of corrosion prevention vs just leaving the inhibiting oil in? It's in my garage, which is dry and insulated but not heated - we're in a pretty temperate location - (East Tennessee). I don't seem to have a lot of corrosion issues with other metal in the garage - tools, bare steel kit parts, etc. - but we're certainly not in Arizona!

Just leave it alone. The factory storage oil should cover you for 1 - 2 yrs. Use the thoughts of your engine rusting up as motivation for you to "Power Build" and get that aircraft built faster. The CH750 is a true 600 hrs build kit.... you just need to build longer days and more often to "Git Er Done". My CH750 was built to the paint shop in 3 weeks. Built 2 wings complete in 5 days (12 - 14 hr days). The entire fuselage built in 18 hrs (minus prebuilt firewall). I built my CH750 at Can-Zac under the watchful supervision of Mark Townsend, and flew it home in a total of 6 weeks. I know some builders want to savour the building process... "Not me, I'm a pilot who is forced to become abuilder to get the aircraft performance he wants" :>)

Bob,
I guess I'm too Type A (or obsessive-compulsive! LOL!) ... I've got about 600 hrs in the fuselage,controls, rudder, flaps, and FWF! But, the good part is I had an A&P IA look it over not too long ago and he simply said "It's perfect!" But, I bought a partially completed kit, so the wings were about 90% built and the horizontal tail was 100% and the slats 100%. So, it's about to come-together rather quickly at the end.
I certainly enjoy the build process, but I'm not dragging it out nor am I in a hurry - I've got another plane to fly.
Sounds like the engine is fine for a few (very few!) more months! HAHA!

John the build process is just just like eating a whole Pizza...one slice at a time. Build a piece and put it aside, build another piece and put it aside. Then comes the day when all the parts you built are gathered togather and you start to assemble the aircraft as a whole. All of a sudden that "Extra Large Pizza" was'nt really that big after all. :>)
