Most likely spun a rod bearing over the weekend at Calabogie Motorsports Park. Started to hear a very loud metal clanking sound and cars oil temp went to 285 (water stayed at 206F max) before I had to call it quits and come into the pits. This is on a track only car for the past 4 years.
2011 135
N55 engine
Manual Transmission
Oil change interval every 20 hours for the last 4 years
First 2 years of track only was using oem 5W30 and then switched to Motul 300V 5W30 for remaining 2 years.
I am original owner - 31k miles mix of track and daily driving, 4k Track only, total 35k miles
FBO with MHD stage 2 OTS tune
May have over revved car during the first session on Saturday but the data suggests I did not go over 7K rpm. Problems started happening after this point.
Have not removed oil pan yet to inspect as I just back yesterday and doing some research now on my options. Car still turns on and runs but with a loud metal clanking noise.
Looking at the MMP rebuild option as it seems the most cost effective and would have a built motor. Could do a lot of the labor (removing and installing engine) myself.
