Been steadily chipping away at the wagon's projects.

Done:
-euro headers/cats
-new pre cat o2s
-radiator/thermostat/water pump/piping/expansion tank
-rebuilt fuel injectors
-head gasket
-secondary air pump delete
-M3 MK60 swap

Left to go:
-rod bearings
-clean ICV
-reassemble airbox area stuff
-euro tune. Probably a PC tune on that, once Brexit drives the gbp down.
-ecu fan
-all fluids

Feels like I'm almost done! Should be wrapping it up just in time for spring

Installed a bucket seat in the M3 wagon.



SYT Shadow and his brother came down for the weekend, and we did rod bearings on the wagon's S54 and some projects on their F80 M3 CS.

The bearings only have 50,000-60,000 miles on them, and only one track event AFAIK, but oil analysis said they were due.





...And it looks like oil analysis did not lie.

These bearings were WPC treated. I haven't seen any cars with WPC treated bearings with even half this mileage, so I think it's possible (but in no way guaranteed) that this shorter life is a result of the WPC treatment.

I put in new, OE, untreated bearings with OE bolts.

Thanks again, Nick/Danny, for coming down!

Had a couple hours to work on the wagon yesterday, so I got some stuff done...
-new OEM hood struts (didn't take any pictures)
-new OEM warning triangle with OE mounting bracket. Didn't actually look like it would fit, but it did :P

-put an oil pan back on. This ended up being a bigger project than I expected. One of the POs had stripped the drain plug hole, so I wanted to replace it. I bought a new (used) one off an engine that TTFS blew up with shitty tuning. It was a new design than mine (came off an 06), so I ended up having to go back to get the pickup tubes, too. Then it turned out that BMW had changed the oil temp/level sensor from being mounted with bolts to mounted with studs, so had to get some hardware for that, too. Anyway, that's done now :P

-replaced the engine mounts and steering guibo. No pics
-revalved the power steering pump to decrease the assistance by 25%. No pics
-replaced the passenger front control arm with OEM (Lemforder)

So, this winter/spring I did a ton of engine projects on the wagon (was running when parked, but things need refreshing at 200,000 miles). Entire belt drive system (belts, tensioners, idlers), cooling system, fuel injector rebuild, rod bearings, idle control valve, valve adjustment, and did euro headers/cats/tune (with new precat 02s). All told, there were a couple of areas where I could have done something that would ruin the engine.

A couple of weeks ago I fired it up for the first time to do a test drive. Drove around the block-- everything was fine. Relief was felt.

The next day I was driving it to bimmerworks for state inspection (lapsed while the car was apart). I was enjoying myself (within the restriction of engine break in RPM and throttle) and remembering how much I love driving this car. Life was good....

... and then I came to a traffic light, and suddenly the car started running more horribly than any car I've ever been in.

I had to get to our baby shower, so I abandoned the car in a neighborhood. But, that evening hail was in the forecast, so instead of dealing with it myself I called a tow truck and had it flatbedded to bimmerworks for diagnostic. I wasn't feeling very good about the situation-- with how much engine internal work I had just done, it seemed somewhat likely that this was going to be a big issue.

But then, the next morning, bimmerworks emailed me these pictures, and life was good again





This was a fuel rail bolt. I had dropped it when reinstalling the fuel rail, and thought I heard it fall through. I couldn't find it at the time, so I replaced it with another bolt I had. Turns out... it didn't fall through. When I came to a stop at the traffic light, it must have fallen from where it was hiding and blocked the throttle arm, holding them closed. With no air, the engine was not happy.

Anyway, that was about as pain free of a fix as I could have hoped for! I've driven the car another 800 miles since them, and am feeling pretty confident with the the car again

Made sport mode a valet mode, in case I have to let someone drive the car.



Used paffy's mssflasher to reflash it when done, which was crazy fast. <10s to flash it, for sure. I bought it to reset the flash count on my M3, but will be using it for all future flashing on all 3 of my MSS5X's!



Second M3 seat in!

I don't know if it's the euro headers/cats/tunes, or the general refresh of everything (e.g. 200,000 mile fuel injectors), but the wagon is feeling notably faster after its winter refresh! Butt dyno says I picked up an easy 20-30 hp.
