What did you do for your M3 today?

[Slideways]

It's finally rod bearing time. Got the top of the engine bay prepped yesterday and came across some annoying finds. Biggest one is that my water pump has been leaking and the shaft has some play after only 3 yrs / 17k miles. Idler/tensioner pulleys are all gone too. And I'm gonna bite the bullet and do a PS refresh because I have a few leaking lines.

Anyone know where to get the AC (spring type tensioner) pulley only? Really don't want the whole tensioner.

They don't sell it separately. For stuff like this, Sreten at M539 buys the complete assembly from a certain aftermarket brand and transfer the pulley to the genuine unit. Some of the aftermarket ones come with quality brand pulleys.

I believe you could also convert the AC tensioner to the hydraulic type, same as the one for the drive belt. That pulley you can buy separately. Unfortunately, you do have to get the whole unit for the conversion.

After 5 hours of baseball beginning at 8AM (I coach both kid's teams), continuation of my BBK installation today - Pierre is not really helping.

Shaved the front knuckles and trimmed the rear dust shield, treated the raw aluminum and tin with POR rust preventative, and now that it's dry I've installed RR brackets. After test fitting the brackets I do not need any spacers to clear the ZCP/CSL rotors… should be smooth sailing from here.

After a year of meticulous planning and research, the car finally arrived at the shop for RACP reinforcement and major suspension overhaul.

Many thanks to Matt at Eurompire in Charlotte, NC for all of the coordination and efforts the last few months. he’s been great to work with!

Finally got my euro bumper on. Damaged my original one on a rogue parking strip that I didn’t see

shop had a hard time with the fitment but the trinity motorsports adjustable mounts helped a lot.

paint correction is up next, the m needs some tlc

Got a part number for the inner / outer CV joints?

Mike:

My axles are from The Driveshaft Shop. They don't show a part number on my invoice for the driver's side inner (attaches to differential) CV joint but it's a 108MM, 36 spline CV joint.

The BMW part number for the CV joint is 26117841003.

Coolant flush, thermostat, gaskets, and coolant hoses replaced.

Paid $3.74 for Shell 93, made me happy. Enjoy the little things in life.

Refreshed (clean & regrease) the rear axles. Needed to replace the driver's side inner CV joint as it apparently overheated (nice blue tint) causing pictured damage. To help, I heat-shield wrapped the exhaust pipe which runs directly underneath the driver's side CV joint. Fingers crossed.

After procrastinating for months, finally did the rear quarter seals. 😅

It was cathartic.

I have another stubby sitting on a shelf in the garage if you want it.

damn, I ordered one, should be here tomorrow. Thanks

[fattycharged]

Thanks for posting pictures of this mount installed. I will be placing my order. I appreciate your recommendation!


EDIT: I just placed my order for one of these exhaust mounts from Rogue Engineering.

Same, I have to order one as well. One of my stock mounts is torn, so great timing on the suggestion

[cakM3]

Yes, it will limit movement of the muffler and should last longer than stock (FWIW I've only been running (1) of these for almost a year). To me it is just a great product overall, you can buy shims if you need to change the position of the muffler relative to diffuser. 1 track day down and no issues for me





(my diffuser fitment has been screwed up for some time, please ignore hah)

I managed to limp on and off the freeway ~20 miles over 2 hours… had to keep pulling off to the side with hazard lights and letting the car cool down just enough to get the SMG cog light to turn off.

Needless to say the clutch fan is back in the car and I now have a clutch fan delete cap to give away!

Also for SMG cars (I Love my SMG and would never swap to 6MT unless I had no choice) Do the SMG pump relocation, Thank me later LOL (it works in our extreme weather)
