Pull the sump plate... Its a 20 minute job. Post pics of the sump plate without cleaning it... Use some sunlight if possible to expose the metals that are suspended in the oil that remains in the plate. Sunlight does the best job of waking these wear metals up for a photo.
With these engines one way to reduce a rod knock is to remove the oil filter element. This opens the oil volume up by 30% and the higher volume of oil will remove the noises.. This is an old trick that shady dealers have figured out. In last week’s class here we disassembled an engine that had a failure occurring and also had no filter element.
Sounds like you got hosed.. It happens everyday with these cars, and we get the phone calls.
UOA tests for debris thats very small, less than 40 micron. Most analysis will not even detect debris larger than 40 micron.
Happy to help, but I won’t be on the forums this week, as I will be at Amelia Island supporting one of my engines that I built for the Revs Institute. I won’t be on the forums much at all, if any through spring. Taking lots of time off starting very soon. Submit a support ticket at www.flat6innovations.com and my team will help you.
Well I dropped the sump plate tonight and the situation is seemingly getting much worse. I don't have a lot of hope at this point for this engine. As shown in the photos below, there are metallic bits everywhere, including many large chunks. I grabbed the biggest chunk I could find and cleaned it up to see what color it is. It has a copper or brass color and the chip is huge! If it came from a bearing, I can only imagine there can't be much left of it. I'm guessing it's time to pronounce this one dead and send it in for a rebuild unless one of you can convince me there is still hope... not sure if there will every be hope in this one but if someone could comfort me for my loss that would be great too.

I see at least 3 significant wear metals in those pics. Please don’t start it again.
Time to issue another Death Certificate. That makes 3 for the day.
Yup. Time for a full rebuild, I’ve seen worse that has been resurrected to see the road again. Biggest unknown at this point is the condition of the crankshaft. As far as I know, there is no regrind possible of either the mains or crank journals.
the upside is: if you take the experts advice and follow it through to completion, you could end up with an increased displacement, high horsepower, very reliable engine. If you have the wallet for it.
if the thought of putting 5 figure sums into a rebuild makes you weak in the knees, sell it as a roller and move on to look for another car.
Better days are ahead.
Thanks for the reply, Jake. I definitely won't be starting it after I saw what I just saw. Would there have been a way to detect this without draining the oil? Would a PPI have even found this?
As for the PO, I don't know what to think yet. I bought it privately and he only owned the car for barely over a year and I don't know if he was smart enough to pull something like this off. He clearly didn't know much about cars and I answered a few of his questions about this car. Maybe he was playing dumb but if he was, he was pretty convincing. I would guess that he bought it that way and drove it until it needed maintenance. There were other problems like brakes, janky door handle, and the brake wear sensor/wheel speed sensor harness was broken on the left front which threw 3 dash lights. At least that was a straight forward diagnosis and fix for me.
A good PPI would definitely caught this, inspecting the oil filter and dropping the sump are fairly standard procedures by Porsche specialists.
i know Jake’s includes much, much more than most.
This sucks... Its happening all the time.
You simply have to do a PPI, and that PPI has to be semi- invasive. A proper PPI would have done exactly what the purchaser did, then the purchaser would not have purchased the vehicle..
People get too damn anxious, and they end up being in a hurry to get ripped off.
Therd is no way he was driving around and didn’t realize he had problems. Way too much to make the lack of a filter coincidence, even the worst oil change place would know it needs a filter put in the housing. I personally would try to pursue this legally.
