About 5k miles ago, I performed my first full oil change with the new swap, and followed the factory specification of 6.9 quarts of oil. Fast forward to today, auto-x time. I do a couple of hard runs, and all is well. I go to my work assignment and about an hour and a half later, and I start the car up to take my missed runs, but when the car was started, I heard an extremely loud ticking coming from the engine. It sounded as though it was low on oil, but it wasn't; the dipstick read FULL. Extremely worried, I scramble to the guy who designed the course, who just so happens to have a '95 M3 with the same exact engine. He tells me this is normal after a hard run, but he fills his up to 8.5 quarts instead of the factory spec 6.9. Apparentely, you need about 1.5 quarts over factory spec to auto-x with this engine, he tells me. He filled his with 8.5 and showed me the dipstick; it always showed full, never over, even if it was filled to the factory spec, he told me. I filled up the oil level to about 8.5 quarts but the ticking was still there, so I shut the engine off and let it cool off for a while. Once started up again, the ticking was gone and it was as though nothing ever happened. Has anyone heard of this before? I find it hard to believe that the engine would require 1.5 quarts above factory spec to be 'run hard'. Any comments?
