PURGING of 912ULS in RV-12
in 912 / 914 Technical Questions

I am nearing the point where I will be initially PURGING the oil system on my new RV-12 (912ULS). The way the RV-12 engine compartment and oil hoses are configured, the end of the oil hose that is disconnected and allowed to drain during the PURGE is situated above the oil tank and engine crankcase. Since the spark plugs are removed during the PURGE, there will be no crankcase pressure to force the oil up and out of this elevated hose. As a result, the oil will pool in the bottom of the crankcase during the PURGE. Is this a problem?
My plan is to do the PURGE, reinstall the spark plugs, reconnect the oil hose, and then do the BURP thing to push the oil pooled in the bottom of the crankcase up and back into the oil tank. Is this a reasonable approach?
Many thanks for your input!
ps -- I don't want to disconnect the oil hose at the bottom of the crankcase since it is difficult to access it there.
