  1. A second opinion from another builder confirms that the AOS probably failed, but he disputes that there was starvation. He says the engine has weakness in the rod bearings that does not allow enough oil at high rpm, and the AOS failure probably caused some hydro lock that exerted too much pressure on the pistons. Lots of opinions.
  2. Talking with a local engine builder here in town over the phone, it looks like the gold flakes are a failed connecting rod bearing. It most likely failed due to high cornering Gs that starved the engine of oil, probably damaging the rod and crank. I guess an upgraded baffle may have prevented this. The earlier misfire codes were troubling, but may have been the AOS being overwhelmed and spraying oil into the intake, momentarily fouling the plugs on that bank. I guess can happen if the car is topped-off with oil while tracking, which I did--he recommends running the oil on the low side when a
  3. I could probably find a rebuild I could live with, but having had the taste of the track I would be on a slippery slope to necessary replacements and upgrades that would definitely exceed my budget. I may not be comfortable pushing the car again which would completely defeat the purpose of ownership.
  4. I am investigating rebuilding, but as you say, unless I plan on keeping the car for a while it is not worth it. The car really only has value to me at that point since it isn’t a perfect car. Honestly, I didn’t pay much for the car, but have spent a lot of time and effort fixing little things that probably don’t matter, but I would just have to start over with a different car. Maybe my car, with a solid rebuilt motor would ok for a few more years. Sent from my iPhone using Tapatalk
  5. Filter will be first. I have the magnetic drain plug, which I may check next, and probably even drop the sump plate. In the past, I have found a few tiny pieces of plastic in the sump, and a few specks of aluminum or other non-ferrous metal in the filter. They never concerned me before as they were very few and tiny. My fear is that it may have lost part of a chain ramp or some other vital in the timing chain path that caused the misfire codes in bank 2 and engine knock, then a chain slackened and skipped teeth allowing the pistons and valves collide. But I am making this stuff up and have
  6. At first the sound was more of a misfire, then the grinding (like road noise or but with engine speed) then the diesel ping/rattle, then the loud knocking—like the rod knock or piston slap examples. This all developed in less than a minute over the course of a half mile, and I couldn’t hear from outside. When I started it at the shop near track the owner/mechanic (a BMW guy) was shocked at the sound. I can repair most things on my car, but I don’t have the time, tools, or space to do much regarding the engine at this level. This is the one thing I worried about. Sent from my iPhone using
  7. Ran a second track day this Saturday. I am a novice, but I could tell the car did not seem to have its normal power after the first session. Second session, check engine light flashed several times when I was coming down the straights. I pulled off track but the light was off. Durametric said code was for misfire on cylinders 4 and 6 (I think) and a warning about damaging the cats, but still, no lights. I cleared the codes, decided quit for the day and to drive into town for lunch. Engine was driving very rough for about a mile, seemed to be delayed coming off the revs and throttle—would sp
  8. I have one. I’ll try and find it this evening...if someone else doesn’t post first. Sent from my iPhone using Tapatalk
  9. I repaired mine. It was actually easy once I got the confidence to crack it open. You need a special tool ($8 and a soldering iron that will fit it) to heat the ribbon connector and peel the old one off and stick the new. I ended up replacing all three LCDs since a second one went bad and I ended up wanting all three to have the same contrast. I can now do the whole job in just a few minutes, but the first time took me hours. I’d say, send the whole cluster off to a repair service to get fixed if you value your time more than I do, or don’t like to take risks. Sent from my iPhone using Ta
  10. Press and hold the down arrow button to bring up the "User" menu. Rotate the selector knob until it says "LED," then use the left or right multi-selector buttons to choose LED OFF. It is in the manual for the radio, not the car, if you still have it. Sent from my iPhone using Tapatalk
  11. I had a bunch of misfire codes on all cylinders and flashing CEL after removing my air box and cleaning the engine. I unplugged the main wiring harness plugs in the passenger side of the engine compartment, blew the connections out with compressed air (in case I got some water in there somehow), plugged everything back together and everything is fine. May have been a fluke. Sent from my iPhone using Tapatalk
