So have a couple questions about it: - I have an oil thermostat installed like this one: http://www.rotaxparts.net/scripts/prodView.asp?idproduct=1302 Is there anything in particular I have to pay attention to to make sure the oil cooler gets properly filled up with this inline? The documentation for it says it's partially open even when cold so I assume it fills up by itself. But not sure. Anyone know? - the manual says to pull the valve covers off and physically check for play in the lifters afterwards (i.e. for the presence of air in them). Is that necessarily still after just breaking the oil circuit open to change the lines? Don't know if that's only for new engines or ?

Here's a link to the Firewall Forward page . Scroll down the page to the entries for Dec 5, 2010, Dec 18th, 2010 and Jan 2nd, 2011. I found that the partially open position of the thermostat when cold wasn't enough to get all the lines full of oil, and you definitely want to get all the air out of them. I would check the lifters as well, although they may remain full of oil. The problem is that you will be turning the prop through a number of revolutions before the system is full of oil again, so the oil may be squeezed out of the lifters, at least to some degree. Follow the procedure described in the Rotax 912 Installation Manual, section 31.11 (available in the Documentation areaof the Rotax web site). It will be easy to see of the lifters need to be re-primed. There is also a video of the priming procedure available on the Rotax Owners site . If you don't already have a subscription to this site, I recommend it for an excellent information resource (in addition to this forum).

It is very good in showing you what to do. -------- Roger Lee Tucson, Az.
