3.6L Aftermarket Oil Pickup for Improved Off-Angle Performance

Are there any aftermarket oil pickup tubes for a 3.6L that move the oil pickup further back in the oil pan? When I'm on a real steep rock my oil pressure light starts coming on. Starts at a bit over a 45 degree incline.

Not seeing much in a quick google search.

Sorry I have nothing to contribute to your solution, but saw this post and am still grinning from ear to ear. This is exactly the kind of problem every single Jeep owner needs to have... spending enough time over 45 degrees to justify a customization. Well done sir! Well done indeed!

That's interesting...
I've been steeper than 45 degrees plenty of times and never had that issue in my 3.6L.

I assume you've already ruled out being low on oil.

Never had this problem either, and been past 45* many times... seems like a legit concern though. Not sure that there is anything out there to remedy your problem.

What about when you are on a 45deg decline? I have a seasonal creek on my property that I cross back and fourth that has a >45deg puckerish ingress / egress and I never see smoke or lights. Maybe some pee. That’s it.

You could probably just cut up another pickup and extend yours back. Not sure what affect the added tube would have on the pump while the tube pumps full of fluid. Probably negligible. Without a real sump and baffling I would worry more about the potential for cavitation pointing nose down while the pickup is moved rearward. You’re a smart dude so I know you’ve thought about all this and will school me in fluid dynamics and the lubriciousness of pentapoop oiling.

Yes I checked my oil level it is at the top of the dip-stick full region.

Keep in mind angles are mentally deceptive. 45 degrees feels like you're practically vertical. Here's the scenario where I had this happen. I've had smoke on several other occasions but this is the first time I've ever noticed the oil pressure light come on. In the moment it feels like if I even tap the throttle I'm going to flip back, but in reality based on the picture it's no more than 45-55 degrees.

That's a good point and would probably be bad to move it way back. My thought is down usually gets over faster and usually works the engine less. You're not typically spending minutes trying various approaches at a line on a descent. Plus I'm never anywhere near this steep on descent, it'd be down right terrifying.

Here's some thoughts on what may be going on:
I don't think moving the pick-up back would do much good. Not only is the oil flowing to the back of the sump, it's flowing up the "back wall", too.
Additionally, at that steep an angle, the flow of oil from the upper portions of the engine back into the sump will be impeded. The oil is being pumped out of the sump faster than it can flow back into the sump.
