OH NO! did I hurt it??? Oil pressure loss
just my luck, I haven't driven my 951 all year, and its about to snow. So i figure let me take it around the block and put a couple gallons of fresh gas in.
Right after I pull away from the gas station, I get the RED light.... what's going on??? Ouuh OH.... Oil pressure 0 im only going about 20-30mph in 2nd. I think, maybe its the Sender?? But then I remeber I had seen a leak from the Braided hose on the NEW big oil cooler I installed.
I start to pull over, but Im only 2 blocks from home. towing at night etc etc, its going to be a huge hassle.....Im only 2 blocks away.... I decided to make it home. takes me some where between 60-90seconds before I pull in and shut it off.
Was starting to hear the tappets clack when i pulled in.
And yep, it was that hose, it blew off the fitting. had 8qts of almost new 15-w50 M1.
BTW I did throw in 2qt of oil afterwards, which probably did nothing. and after I got situated I just kicked the starter just to make sure the engine didn't lock up.

Hard to say. Based on your light usage babying it on the way home, I'd be tempted to fix the problem, get some oil in it, and put some local miles on it. See what happens. Or you can say this was a sign from the car gods that it is time to change out the rod and main bearings.

Asking us whether or not you have damaged your engine will not give you any information. Drain the oil and look for shiny bits of metal. That will tell you if you have damaged the rod bearings.
The good news is you have all winter to fix it.
Personally, I get the red light, I'm shutting it down. The cost of an engine rebuild is not worth gambling the cost of a tow truck, no matter how short a ride.

Well you could pull the oil filter and cut it open and check for metal. Mobil 1 is perrty good oil it might have stayed in the bearings even as the pressure/flow dropped. Pull the plugs fix the hose put in some oil and spin it up and see if you get pressure.

I vote for better safe, not sorry.
Years ago, I had a customer run his Rabbit out of oil.
We refilled it, ran great, no noises, had fine oil pressure...
Month later it gave it up.
Rod and main bearings were gone, crank was scrap.
I suspect that if we had just pulled it apart first, we would have been able to save the crank and a bunch of labor.
Good news though, Rabbit cranks were almost free.
Dunno what a 944 crank goes for these days...
Pull the oil pan, if the bearings are OK, good news!
If they aren't, the crank might still be undamaged, and you can just roll new bearings in without pulling the motor.
If the crank is damaged, better to know sooner than later.
Let us know what you do!

Well Not sure when I will get to it, as I said the car has been sitting all year, my next step, whenever i get to it, will be to fill with oil, let it idle for a bit then pull the filter and open it up, and drain the oil and see what I see. and keep my fingers crossed.
I actually went back today an retraced the path, could see where it initially blew and followed the trail, had a wider line about half way. the other half there was still a small strip.
It was about 3/4mi.

BTW if it was any further, I would have stopped. I was just circling the block. just over a week ago, My motorcycle broke down and getting a tow home was a nightmare! really didnt feel like standing around for 4-5hours (thought I guess i could have walked home!)

Hard to say.. I had my crank bolt come out a bit and the oil pressure dropped really low. Sounded like a diesel but drove it 5 miles home. Checked the oil and re-torqued the bolt, all was good. Tan fine till I sold
it 5yrs later.
it 5yrs later.

Life is a gamble.
A.) Run it and see if it's F'd up. Hoping it won't suffer a more catastrophic failure later.
B.) Assume it's F'd up, pull the motor to replace the crank and bearings. Hoping you're not wasting a HUGE amount of effort.
C.) Split the difference, drop the pan, inspect the bearings and crank in the car.
If the crank is OK, you can swap in new bearings in place. Even if they're OK... why not?
The F crank bearing might be a problem... I forget if they're the 'full circle' style.
If the crank is F'd, well, the engine will probably come out easier without the pan on it...
Good luck!

well FWIW, I know its not exactly the same thing, but I did put Bestline in my engine, due to ProjectFarms testing. Only time I ever added anything to the oil. Hope it might have helped:
