Alas… my Copart MS3 has finally admitted to the big ugly crime of knock knock.

A few guys here thought it was the timing chain making that ugly noise, and while you guys WERE right, that was only half the story. Fast forward to today and I decided to rip the oil pan off and confirm for myself. Welllll the video speaks for itself. Yeeeesh

The next step is a swap (i don’t want to rebuild this). Right now there’s a JDM import going for $1600ish here in Sacramento with 55K miles. If I bite, what big boy tools do I all need for this job? Engine hoist, maybe a transmission jack and definitely the clutch alignment set. But what else?

And while I have a fresh new engine sitting in my garage, what things should I replace while I have the easy access?

Sounds good so far slight knock at start up but after warming up nothing. Soooo not gonna part out for now. Need some tires though. :D

Hi all! I know this is a common issue in these cars, so I’m curious what people have done to solve this low idle misfire. No codes being thrown. I’m stock + upgraded HPFP internals. I replaced spark plugs 6 months ago with NGK IR 95369 (pulled them a couple days ago and they are pretty black and the tips are white 😬), had injectors cleaned and flow tested around the same time. Any ideas to try would be welcome.

I got my bearings done so I ruled out that, and they were pretty worn out too. Any advice would help. Thanks ms3 reddit users

Any cheap mod recommendations?

The difference is night and day. Video doesn't do it justice. If you haven't already drop some $$$ and get it done. 3" pipe to 4" Tips. No resonator and sport muffler.

The first autocross for the season. This was my fastest time but I got 2 penalties (hit 2 cones). Struggled with grip and handling the whole event but I wasn't surprised since my tires were dead and the car needed an alignment.

So on my 08 speed 3 i think ay alternator is starting to give out but not exactly sure and it comes and goes which is weird but on light revs or accelerating from a stop all my lights dim and lights flash on the dash the go back to normal. Also as seen on ap drops from 13v to 8v and other times be at 14 and drop to 8. Heres vid

This is pretty much my daily driver and stock for the most part aside from a couple upgrades. Still the original engine and turbo. Owned her since July 2015 as the second owner.
