Subject: | Re: Oil sender problems with HKS |
Not sure of your experience level around aircraft - if you put in a
tubing fed pressure gauge on your aircraft, one thing you need to add
is a flow restrictor at the engine end. In the event the tubing
should crack or break or become disconnected, the restrictor at the
engine end restricts the loss of oil giving you time to land the
aircraft. Also Imagine hot oil spraying on your lower body and legs,
or next possible event, cockpit fire.
This is done on certified aircraft. The restrictor is nothing more
than a small component with a small hole in it to restrict the flow
of oil but yet big enough to allow enough flow for pressure to build
or fall at the gauge to register the pressure level changes.

Believe current TBO has been increased to 2,000 hours.
Mandatory for LSA (certified) aircraft, but only "recommened
TBO" for experimental homebuilts.
No way would I tear down a good 912 series engine at 2,000
hours unless there was a foreseen or current problem.
