Oiling issue on the track.... took my motor today

All I can say is that I also lost an engine to a bearing failure but haven't had any problems with that issue since I went to the EBS baffle + 2 qt deep sump + horizontal baffle/windage tray. It basically creates a fixed cavity to hold oil for the long sweepers.

YMMV.

even with that exact setup, I have severe pressure drops

Under what type of conditions? Still mainly in left hand sweepers? And how do YOU address that? Are you using an accusump, like AZ986?

y'all, THANK YOU for this ongoing dialogue. This is awesome, being able to learn from the collective this way..

Under just about all conditions. Left hand turns, right hand turns, pressure consistently dips. I'm not using an accusump.

At this point i've given up on trying to prevent it. I run expensive ass oil (xp6 15w50 as I have an early variocam motor), change it every 2 events, run as much oil cooling as is possible on the factory set up (3rd radiator with a 997 S heat exchanger and fans on high), and hope for the best.

I should add that this phenomenon has been occurring since I installed the motor in August 2017 and there is never any metal in my oil/filter, so who knows what the deal is.

Really though I'm poking around moving up to a 987.2 Boxster S because worrying about oil pressure all the time is just plain no fun.

But did you blow an engine?

If it keeps the engine from blowing up, then I can live with the pressure drops. I'm not looking for perfection, I just want to get a reasonable life out of a motor (without spending the cost of a motor to do so).

no, I haven't popped another engine yet.

First one died due to a bad ring.

Have you ever checked the oil pump to make sure it's working correctly?

yeah, I checked it for scoring. Its not new, but there are no signs that its not operating properly.

It shows about 70psi cold, 20psi at hot idle, and at 3k hot cruise, pressure is about 50psi. All those specs seem to be within the tolerable range.

But when you start turning, it all goes to ****************.
