I installed two quick connect couplers on the side and bottom of my oil sump.

However, before starting, I generally placed a heating pad under the pan for a while to warm the oil up, but not cook it, then I use the old method which is crank it over a few time before a full start, but your idea seems to me has a lot of merit as I am looking to prevent dry starts.

Suggestion
And a good design could include an automated oil change solution, using the pre-oiler pump to move the old oil out, and the new oil in.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Has anyone installed a pre-oiler on their 996 engines? I was looking at my son's airplane and noticed an Infinity Aerospace pre-oiler.

I don�t know of anyone who has done that. It�s a business opportunity, since most engine wear occurs and startup. And a good design could include an automated oil change solution, using the pre-oiler pump to move the old oil out, and the new oil in.
But no. They�ve been around for decades and nobody I know is using them.
I installed two quick connect couplers on the side and bottom of my oil sump. After my daily grocery store run I park in the garage and crawl underneath the car then connect two quick connect hoses to my sump. The hoses run to a oil machine that heats, filters and circulates the oil at a warm 190 degrees constantly 24/7/365. This ensures that my motor is constantly at the ready and I'm certain will prolong the life of my engine indefinitely. No silly bore scoring for me! Nothing worse than starting an engine with oil only at ambient temperatures. That's for nubes. Get with the program. If it is good for F1 cars then it is okay for us 996 poor boys.
DBJoe996 would like to see a pic of your installation, as a solution to living here in the Northeast. While I would like to drive in the winter weather more often, sometimes it just isn't practical as some of the local roads do not get plowed immediatley....sometimes days....the joys of living in the woods. However, before starting, I generally placed a heating pad under the pan for a while to warm the oil up, but not cook it, then I use the old method which is crank it over a few time before a full start, but your idea seems to me has a lot of merit as I am looking to prevent dry starts. Here is what Infinity Areospace web site recommends, in other words
when you turn ON, the Electric Oil Pump turns ON, sucks oil out of your oil pan and pressurizes your engine oil to about 20 psi.
Ummm...I was kidding. I live in Florida and do not have to worry about cold starts when it is 95 degrees in my garage. However, in concept, my idea could work although I don't see the merits in the long run. If you live in a cold climate with snow and salt on the roads, just park your car until it blows over. I wonder how other cars and trucks fair in cold climates when starting up from cold. I lived in Maine for awhile, below freezing temperatures and crap all over the roads....would just go out and start my Chevy pickup, go back in and get a coffee to go, and then just head out. I never gave a thought to starting up cold.
Haha, you had me going too, I didn't check your location*. My Jeep has a built in electric engine warmer and I've joked I should install one on the Porsche to protect it's fragile engine. I mean here in San Diego it dropped to 49* just the other night. The suffering we must endure, the rest of you you have no idea of our pain.
* Of course Florida does get cold enough for icicles to form and, sadly, for booster o-rings to freeze.
It may help the oil pressure drop with hard braking etc. not sure these engines fail from dry start seems to be more of a cooling and sealed bearing issue.
If you are that concerned about wear. Just disable the clutch pedal switch and that will reduce the trust bearing wear a lot. As for warming the oil, install an oil pan heater. No need to over think this and create a solution for a problem that doesn't exist.
Accusump are frequently a solution on Porsche track cars. I have one on my LS e36 and it functions as a pre-oiler and oil pressure accumulator for track days. Cheap and easy insurance so no reason why you couldn't add to a 996 IMO.
I didnt mean to suggest it was necessary, just answering the OP's question on if anyone has installed a pre-oiler on a 996.
With all of the bore scoring issues maybe it is necessary..... There, I did it!
Still, most wear occurs at startup, so unless Porsche engines can run as long as Toyota engines, upwards of 300,000, 400,000, and 500,000 miles, then a pre oiler would make sense.
Oiling system is not an issue on a street driven 996 and this start up wear is so insignificant that it's hardly worth motioning. At the end it's basically an internet myth. A 996 with over 300K miles is worth so little that the current owners will not put up the money for the maintenance of the rest of the car so engine condition will not matter much. Yes, if you dig around the internet you will find a handful of owners in the world that will do keep their 996 going that long but that's a very small number. My '99 has over 200K when I bought it over 7 years ago and the engine was never opened. There was no visible wear in the bores when I pulled to heads because the exhaust valves bent by the previous owner, that doesn't mean the more is not tapered, but there was no ridge at the top that one would expect from a severely worn engine.
Wow, I didn�t know that. I thought nearly ALL ICE suffered from the startup wear, and Porsche would not be any different. I�m surprised and skeptical though still. Are we sure about this?
