Not great oil analysis...
I finally got the OA back from the oil I which was in the E550 when I got it. Noteworthy:
One caveat is that I have no idea how many miles/years were on the oil before I got the car, nor what oil it was. Even still, I don't expect my car to tell me anything twice, even if most of the time it's happy to do so. Another caveat is that I re-use various containers and tubing to do my oil change. I tried like hell to clean them fully but it's possible there was some cross-contamination from another oil source or from something I was cleaning with. Next oil change I will do traditionally through the drain plug with fresh equipment. These potential oil:coolant mixing areas are (along with associated jobs):

Oil Analysis I believe need at least twice or more to see the pattern, but it will be more for metal wear.
But if potassium is there and if that indicated coolant , damn.... https://www.machinerylubrication.com...-potassium-oil These potential oil:coolant mixing areas are (along with associated jobs):
Wish you solve your issue fast. |
Thanks man!
Blackstone wasn't sure the Potassium was from coolant. They listed some potential other sources, but I know the car better than they and I think the clock is ticking. I forgot to mention that of course I will get the guides, tensioners, and the two cam adjuster magnets that I haven't been able to reach yet. And of course the timing chain itself... The job is so big that it seems like it would be smaller to remove the whole front fascia and frame cross member to just get full access to the front of the engine. No sense in trying to do a job that big with 6" of clearance. It's one thing to try that kind of stuff on almost any other car, but the size of the engine with turbos and the number of tubes and pipes on this thing.... This means I need to get the Porsche on the road so I have a car to drive for a week or so while I grind through this... |
