well after months of waiting after a crankshaft failure last august my 185 finally has its heart and lung transplant finished. i upgraded to a factory new IO-550 and a mccauley 3 blade prop. it was supposed to be available this last weekend but the fog thwarted me from getting to fly it. my mechanic wants to do the first flight both to double check that everything is operating OK and to start the break in process. after that his only advice was to go fly and probably avoid a lot of touch and goes for awhile. looking around the interweb it seems there are a lot of theories on how best to break in an engine. there doesnt seem to be much agreement on how long until the cylinders are "broken in". i've seen estimates of 50 hrs total down to "10 hrs after oil consumption stabilizes". it seems i should expect high oil consumption initially but no one says how much is to be expected and how much might be too much. there is also no agreement on which oil to use. i was flying my IO520 LOP and some sources say LOP is to be avoided during break in and some say not to worry. those of you who have been through this, how did you manage this process and how did it turn out? any definite no-nos that resulted in pulling cylinders early? hopefullly i will finally get off the ground next weekend.
