2013 335is 6MT
Purchased at 30,000 miles, went FBO, full e85, 470whp/512wtq at the same time. No real unexpected issues up until now, just the typical N54 stuff. Took it to a track day at 52,000 miles. v8bait made me a track tune that came on more linearly, made HPFP less sad, and ran a bit more conservative in boost and timing. But ask any racer, and real racer, and he'll tell you it's all about the tune. So fuck v8bait and his pussy track tune, I ran the more aggressive daily tune #becauseracecar
Well ambient temps were low, 50*, so coolant and oil temps stayed perfect all day as I beat the everliving shit out of the car. Then coming off a corner engine ran rough, lots of smoke, check engine light, #n54lyfe. Engine runs but runs really rough, heavy oil smoking, limp mode. Drove it home plus another 200 miles like this. Cylinder 6 misfire. Spark plug on #6 is all black covered in oil, the other 5 look perfect. Disconnecting #6 injector makes engine run more rough.
Hypothesis so far is I melted #6 piston. So engine comes out for a cheap rebuild. Here's where I'm at so far. Thankfully I've got the man's transmission and man's RWD. The automatics, and the AWD, make pulling and dropping motors significantly more difficult. Cradle wont have to be dropped, no axles to pull, no driveshaft to pull, no trans cooler in the way, and no trans lines to get in my way. VRSF downpipes also help as I dont need to worry about breaking the damn downpipe studs. On a side note, the VRSF bolts/nuts still rust and seize, I broke 1/4 on removal. I'll replace all 4 with stainless hardware.
So far I've made huge progress in a month and a half. I got the bumper cover off, and almost got the intake manifold off. So stay tuned because I move fast.
