I've had them loosen enough not to be obviously loose (still seemed tight) but enough to enable air to be sucked in giving a jumpy oil pressure gauge reading (needle repeatedly flicking down to about 5 psi below normal indication; a mechanical gauge used to check this was yet more violent). I think the leakage had more to do with the machining accuracy of the ball fitting rather than the complete tightness of the nut per se. I've seen others' that were loose, but may not have been tightened sufficiently after intervention (thermostat fitting).

The birth of an airplane, stirs many emotions. Relief, joy, anticipation, doubt, and pride. What makes an airplane meet all your expectations is attention to detail, confidence in your ground testing and your flight preparation.

Ron, I have found the nuts on the cooler not completely tight on some occasions doing pre engine run checks on new aircraft. Normally the client has failed to seat the cup and fitting well before attempting to tighten and then snug the fitting, as they are concerned about overtightening on the tank and cooler which can damage a fitting. The oil cooler tightening is a bit of a concern as the hoses are pulling during the tightening sequence in some instances. To make the whole process easier in the shop I would slack the oil line, position the fitting and hand tighten the nut. Wiggle the line and tighten some more. Difficult to do in place. I drop my oil coolers as far as possible and do not use the 90 degree fitting supplied by Europa. I order a straight fitting for nearly all my clients to assure an easy and CFC standard fit. By lowering the cooler well below the duct top, I find getting to my nuts much easier and is a great help during servicing and inspection as the fitting can be tightened and inspected below the duct metal top quite easily. Personally, I cut the handles of the wrenches needed to fit the cooler fittings so one can get to the fitting easily and properly snug the nut. Special tools for a special airplane I guess. Once tight, wiggle the hose to assure there is little to no torque on the fitting and check the fitting again. Apply torque seal paint as an indicator for inspection. I find the nuts on my coolers do not loosen. Note: The 90 degree fitting supplied in conjunction with hose routing can cause a loosening torque that can pull the fitting. If truly concerned there are remedies to help safety the nut. 1. The nut cannot be drilled for safety wire so one can use a Breeze clamp shaped to the nut flanges and tighten the clamp. Then safety the clamp screw. Use the clamp worm fitting as an anchor then to safety to the other fitting. This is extremely difficult to do after the duct is installed. 2. Loctite can be used on the threads also. Personally, because I use the straight fittings on my duct, I have found no reason to use safety wire or Loctite. My torque seal paint has revealed no movement and on my 5 year removal of the duct and flush of my coolers, all goes back together well. I do use the "Breeze Clamp method" on my oil tank however as I use leaded AVGas for fuel mostly and every annual, I pull and clean my tank to see the performance of my lead purging. I also have had my return line loosen one time in 15 years on the tank due to engine start and running vibration I suspect. Post mortem revealed an oil line a bit too tightly bent so as to push on my fitting. I was suspect of my fittings may be leaking so I "Breeze clamped them. Come to find out the oil filler cap seal was poor. (Try to find just that rubber gasket! Rotax wants you to buy a new cap!) So to service my tank, clamps get loosened and refitted at least once a year and the belts and suspenders clamp and safety wire is a confidence builder for me. Trust but verify as they say.
