Guys, I am surprised with all of the information. I really appreciate it. The CAMit info is interesting. I plan to give them a call. I can't help but be suspicious of the relief assembly. I have thoroughly enjoyed my Jab up to this point, good performance and temps have been good all the way. The thought of a rebuild is troublesome. I am hoping to find a economical, yet, good solution.... I will update my findings as I go. Thanks for the info once again. Phillip

Appreciate the responses... Going to check clearance on the oil pump gears this weekend and will take a good look at the relief valve for wear or insufficient seating. I am puzzled by the Jabiru at 420 hours on a 2000 hour TBO. I am curious about the machined seat on the CAMit mod. My engine casing has a snap ring groove which secures the outer washer and the pressure relief assembly. How do they do the machined seat? The other thing that puzzles me about Jabiru is 3 washers under the spring(max according to manual) from the Factory.....Has anyone ran across that?

Hello all, I have a 2200A ser#1932 that has started running below the minimum oil pressure. I have about 430 hours on it, at cruise 2600 rpm it is fluctuating from 26 to 31 psi, minimum is 31. Checked pressure relief valve assembly, no visible issues. The motor had 3 washers under spring from factory. Anyone got any ideas? I have talked to Jabiru and they have suggested checking clearance in oil pump, then bottom end if no clearance issues. Needless to say I am concerned about that step at just over 400 hours. I am running a oil cooler and have read about braided line and even a retro fit for the 3300 pump. Looking for experience, ideas and suggestions. Thanks in advance. Phillip
