Just a reminder regarding winter operations; cold oil pressure can quickly build
high enough to rupture old lines and dirty oil coolers. Never advance the throttle
until those temps come up. Hopefully, the PIC will do a visual check before
strapping in.
On Yaks/CJ's equipped with remote oil filters, it is the rubber seal in the filter
that SHOULD blow out first. This is much better than a line or oil cooler
rupture. The best Prevention is to move South :) failing that, use a heated hanger
the night before ops, every part of the airplane gets warmed. If using heat
pads, don't forget the oil cooler.
The filter base and elements I supply with remote kits are rated for 200PSI, that
is a common value for most equipment on the market. 200PSI can easily be exceeded
in a cold oil cooler when the PIC grabs a hand full of throttle.
Stay Safe... I'm going to stay warm.
