Dynon DS-10 no oil pressure

[Slyfox]

Jay, a mechanical gauge would be a real good idea at this point. as far as the sensor you have with the dynon, maybe you should inject air pressure into the sensor to see if it will read. If it does read than you might have air in the oil system on the engine and you will have to get that out. the best way is to inject air pressure into the vent on the tank while cranking the engine(make sure the tank is sealed with the cap on). I generally use a free flowing air blower and limit how much I pull the trigger. Don't run that engine until you know you have oil pressure. you could just leave the sensor out and see if it shoots oil out when you crank the engine, that will tell you real quick if you have pressure or not.

the most important thing is to know your engine is making oil pressure. hope this helps.

I just ordered a lube pressure test kit with the right nipple and a gauge. I also ordered the Kavlico oil sender to replace the one that came with the engine. The Dynon install manual recognizes the part number but it also said that they use a Kavlico sensor. I figure if they use it for the Dynon, it's probably what they actually have success with. I"ll check back with you in a few days when I get the parts. I hope after everything is up and running with a smooth pitch and a full RPM at static, that it starts to rain and hail with 40 degree crosswinds over my runway. Then and only then will I believe that I have arrived.

Sounds like a plan, FWIW I also use the Kavlico.

i was unable to use that fancy oil pressure transmitter that came with the engine as it wasn't compatible with the grand rapids eis . had to install the old vdo xmitter.

I installed the test kit gauge.
I did an engine purge procedure by the book.
I got pressure on the gauge in a few turns of the prop.
I completed the purge, checked the valve tappet clearance and buttoned up the engine.
Tomorrow will do a test start with the direct pressure gauge in place. Will do run up and leak check. The Mechanic will sign off the engine and a/c inspection if all goes well. I'll let you know

Awesome Jay! Congratulations on a challenging engine upgrade. I have no doubt you will love that plane.

Real good news Jay. Oil presure always a good thing.
