Stored Rebuilt engine - maintenance?

[C500]

Hi gang,

I had my engine professionally rebuilt almost 2 years ago. The resto is still underway, and the engine hasn't been turned over in that time. The engine has been wrapped in plastic. Any advice on maintenance I should do for the internals at this point?

So if the Engine was professionally rebuilt it was probably Dyno'd and put through it's break-in paces right ? 
Cam run-in, Rings seated, etc ?

No matter,
usually a good idea to keep a new engine away from dramatic Temp/Humidity changes ?
and,
periodically give it about a half a turn(few weeks/monthly) so as to not leave any one V/Spring in a compressed state forever ?
But that can also depend on what type of build Cam/V-Springs etc., some would even go so far as to recommend priming the Oiling system periodically as well, when following the turn over "regime" just to keep Lube up ?

What does your "builder" recommend for 2 years of storage ? and if NOT Dyno'd/run ? ..... what to do to maintain their warranty ?

It hasn't been dyno tuned or run in. The guys that rebuilt it don't have a dyno and it hasn't been turned over by hand since. Cam is a crower HDP 271. I can check on their warranty maintenance later today. What would you suggest for the block at this point?

I hope they used LOTS of assembly lube and there are desicant bags inside that plastic wrap. Was always my fear when I sold guys freshly overhauled aircraft engines, that it would take 10 more years until they got their airplane built and just leave the engine in the corner waiting while the camshaft turned to dust. I always had them turn the engine upside down, cork what was necessary and fill it full of oil, not sure the best action on an auto engine, but I'm sure the builders will fill you in on how to proceed.

If it was never run, i would tear down, reassembly lube and inspect, then prime before breakin. Asking for trouble if you start it as is.

Talked to them yesterday, and they advised to spray the bores with WD40, and turn the motor over by hand. Bottom end has been well oiled. They have recently acquired a Dyno, so will take it back there for break-in

How far would you tear down?

[c00nhunterjoe]

Depends on what it looks like when you start opening it up. The drier and rustier it looks, the further i would go. Cant really answer it until you start into it. Might be perfectly fine but its not a gamble i would take.

I'd just take it back to them for Dyno'ing closer to when you are ready, and let them check/do whatever they want before firing ?

Chances are depending on the Lube used ? that the F.T. Cam lobes may be dry.

Thanks gents, I'm not taking any risks, will take it back to them for a check and run-in on the Dyno.
