If I did that, told everyone, then started it and blew it up Id go into hiding 🙄

1) Pull the fuel pump fuse
2) Crank for 30 seconds to build pressure
3) Replace fuse
4) Start engine and cross fingers....

Uh.. You better make #1 Put oil in it. 🙄

I guess they don't make em like a Mercedes. 17 minutes driving with no oil before engine dies.

ehh... can you stick to 986forum trends, please?

The noise from a car ramp sliding on concrete will cause explosions, apocalypse, holocaust, extermination and our planet will turn into a star if you don't flatbed and foot a $3000 expert invoicing.

It is what it is man. Serious stuff :/

you've scanned your car lately?!

There's an old joke about the Mercedes 300D, where the transmission had fallen out, but the car ran fine for another 100 miles or so, on its reputation.

To give you a little hope I did this years ago with a car as well. I couldn't reach the oil filler while the car was on the ramps so I just hopped in and drove it off with no oil. Probably ran for 5-8 sec with no oil. Boy did I feel silly once I realized what I just did.

I did not have the internet to turn to or a Durametric to tell me what has failed so I just filled it with oil and drove it as normal for the next several years. There were no apparent consequences. I can't remember what car it was, Maybe a Mustang 5.0

Anyway good luck, but my money is on the engine being fine.

Unfortunately there is a lot of difference in that engine and his. I used to run a dealership and during Cash for Clunkers we were required by law to blow up the engines on the trade ins. We drained the oil, added "engine blower" for lack of knowing what the government supplied. All the import high tech engines blew within 60 seconds. The Ford big old V8s ran for an hour before they even started to knock. Several never blew up even after running for hours. Some we drained the coolant and they still wouldn't lock, Got really noisy but would not blow.
One of the mechanics told me that the imports were build to higher tolerances?

All about assembly's rigidity. See it like Alusil blocks (Porsche?) vs steel casting blocks

I've once been told to avoid hot spots on AL (e.g. no oil/rotary,1000rpm loll). AL normally twist as a result. And screw up main bearings and other stuff.... like gears

Yes. If the engine is damaged it will cost more to repair than replace. I wouldn't wander too far from home for awhile.

Agreed, just put oil in it and take out the fuel pump fuse so that the car cannot start and then crank the motor until the oil pressure light goes out. And I wouldn't sweat it too much. I know it's a different motor, but many years ago I had a Fiat 850 that lost all of it oil while I was stopped at a stop sign, I saw the oil pressure light go on and I immediately shut it off, but I did hear a bit of a rattle.

after I put oil in to it, it rattle a little bit when i first started it but after that the car ran fine. Well, is fine as a Fiat 850 could run.

+1 to above. Hope you get lucky!

If it were me, I'd probably fill her with oil and then pull the front engine cover (behind the seats), put a long handled breaker bar on the front pulley bolt, and slowly turn her over twice by hand (with the ignition off). Maybe even pull all the plugs to make turning her over easier. If I didn't feel a piston hit a valve, I'd pull the fuel pump relay and crank her over by key until the oil pressure light went out (to pump up the tensioners without starting it). If that went well I'd reinstall the fuel pump relay (and plugs if I had pulled them) and say a little prayer before trying to start her...

The noise you heard could have just been chain rattle because the tensioners weren't pumped up. But 5 seconds is a LONG time, and there's a chance one of the chains jumped a tooth. If it did, the damage is probably already done, so I don't think proceeding the way I described above would hurt anything. But I'm not an expert... it's just what I would try...

Sodium silicate. Also known as "liquid glass". Used in some coolants, and in many of the "stop leak in a bottle" type products.

That's interesting about the dramatically different engine running times before seizure.

Yep that's it. It was actually fun blowing those cars. We probably went through 150 cars.

So is there an epilogue to this story? What did the OP do and how did it turn out?

Exactly! Some of the commentary may have been a bit harsher than it could have been, but I think everyone is rooting for the OP, and wants to know the outcome. At least I am!

He's busy driving it loll. He'll be back I'm sure...

[Mauiguy]

I meant to post sooner, but I forget stuff...
K so I got it to my local independent Porsche mechanic, and he agreed with the "Pull the fuse/relay and start it and let pressure go back up" type method several of you posted in this thread. The car started fine and he told me about the components down at the bottom of the engine that are usually bathed in oil when the normal amount of oil is in the car (I think he mentioned the tensioners). I did a short test drive initially and everything was normal, and will probably take it on the highway this weekend.
Thanks for all input, much appreciated!

Congratulations! You dodged a huge bullet. Thanks for posting the update.
