Years ago I ran my Panther without oil for about 1/2 mile (30-40 sec) trying to figure what alarm was going off. Apparently the oil filter spun off and drained all of my oil in my bilge. Put another filter on, ran it, cut it open and decided it was good to go. Never an issue. Don't know how the filter came loose, because when removing them for oil changes you'd think they were welded on. I think someone was trying to sabotage me...

To the OP...all above advice sounds perfect to me. No noises and check the filter for bearing material and if clean send it! Lol

FWIW way back when we had an old chevy wagon we were going to use for a beater drag car so we didnt need the I6 engine but someone wanted the oil pan off it. we got bored on night after pulling the pan off and fired it up and let it sit out in the field with no pan on it. it idled for 30 minutes or more before it got so hot it was glowing and we shut it down before we caught the field on fire so 20 or 30 seconds is probably not the end of the world. on the flip side we raced in the Bahama's one year and the dry sump belt broke so the throttleman shut it down. owner asked what the problem was and then said "I have never liked this set of engines so go ahead and run and we will see if it makes the last straight away to the finish." for the record an open class engine will run 47 seconds at 7800 rpm with no oil pressure. yes it was a catastrophic failure that I had to clean up.

I lost oil pressure on my last engine for a very short period of time . Guardian mode shut me down.
Bearings looked like $hit and it didn`t last long after that.
That being said I was under power , just hit a huge wave and it launched the boat , came down to earth with no oil pressure.
next day fird right up with good oil pressure .. weird.
I got evidence :-)

Nice setup. I have System 1 filters, but I'm not sure yet how I want to employ them. 'Gotta check the screen micron first. I was planning on full filter no bypass with parallel filters.
I got bit once by oil bypass. Rather not have it happen again.

On tear down...did you ever find the cause of the oil pressure loss?
That would drive me batty...
Similar to the Gen6 7.4 L29 Merc core I'm tearing down. Owner claimed oil pressure dropped to 10psi. 600hrs on it. So he just changed out the long block. Now I'm tearing it down looking for evidence of low oil pressure. Have not seen anything yet. I did see the front main gallery plugs have weep holes on them for the timing chain. Rod and main bearings look ok so far.
