This year we have had limited flying in the UK due to long periods of rain and now approach our first winter with our recently bought Jab 430. Is there any guidance from the manufacturer on best practice for "winterising" the engine over the next few months if we cannot get it out of the hangar and run up to full temperature....or is even this detrimental to the engine?
Our engine maintenance manuals have detailed instructions for storage of Jabiru engines. See section 7(gen 3) or section 6 (gen 4). We do not recommend running the engine as part of storage as it is hard to get the oil up to temperature without risking overheating the heads. It is far better to take it for a flight if you want to run it.
Thanks for that, I understand the thinking on design level air cooling of the cyclinders in flight, but our 3300 is fitted with a TOCA to divert oil away from the cooler until reaching temperature and we monitor CHTs on all cylinders. If flying is just not feasible, would you still advise only the 5 revolutions by hand every 15 days is enough to circulate some oil with anti-corrosion properties?
Yes, would advise inhibiting the cylinders and rocker chambers and then rotating it by hand every 15 days.
