| Subject: | Erratic oil Pressure in 912 |
Lately I have been experiencing erratic oil pressure in my 912. Upon startup I
get instant oil pressure as normal. After warm up and takeoff I fly for awhile
and sometimes my oil pressure dips down to 20 briefly and goes back up to 40.
This may happen several times but usually not when the engine is good and hot
say 200f degrees. I'm using 20W50 Honda oil. I know that's a bit thick for winter
but it averages 60f degrees around here. Any ideas?

Hi Pete,
Probably one of two things. It is either an oil pressure sender starting to go
or my first choice is a partial or intermittent ground.

I had experienced this a few times in a KF 4 with 912ul that I purchased this past
summer. Somewhere on this site I read the obvious to double check all electric
connections especially the "grounds" and when doing this I noticed a "ground
wire" that appeared to be attached at a point where there was paint and possibly
not making a good consistent contact. I sanded off the paint to ensure
I would have good metal to metal contact and I have not had the problem since
(>40hrs). I can't be sure that was the problem, but again I've not experienced
it since. I also believe I read that it is normal for the electronic gauge to
show a little higher pressure at lower rpm's than at higher rpms (cruise) and
I have noticed this as well. I have a Westberg Quad setup model 3AQ4-41mm.
I'm no expert, but maybe this will help, Paul Perry KF IV 912UL
