Jabiru 3300

[VFR Pilot]

Help.

 

I have a hydraulic lifter 3300 engine, one of the last one's before they changed to the roller follower's.

 

I am reading 32 psi oil pressure on my instruments at idle but don't have any oil going to the top end.

 

The oil cooler and oil filter are cold but the sump feel's warm.

 

I have had the lifter's apart and back together again, Is it possible for the oil to not get past the lifter's if I have put them back together wrong? (ie possibly the little plate's at the top upside down)

 

Any suggestion's/help would be most appreciated.

I'm sure you'll get replies from people more qualified than me VFR pilot, but I am qualified to say that of all those apostrophes you used, only one was necessary.

There are two ports on the front, one where sender normally is and one below it

 

Normal position measuring pressure after pump, before filter, cooler and engine, other position is after engine and everything.

 

Measure pressure in second port to see whats really happening

 

Hydraulics are very sensitive to correct pressure.

 

Also Jab supplied pressure senders are ordinary and read incorrectly. Common failure part. Try a second one (VDO part) first as there may not be an issue at all.

 

Its possible something is holding regulation valve open.
