Project Chronicle

It has been years since I had a hobby car I made an excuse to drive. Despite having an ongoing rotation of vehicles stretching back about a decade now, it hasn't been since my departed 1995 M3 that I tried to find excuses to get out for a drive - but I've found that in the car infamously known as the clownshoe. 

The 2002 BMW Z3 M Coupe is quickly nestling its way into my cold, dead heart, blending together all the rubber-bands-and-bubble-gum construction of an E36 car that I find so endearing along with the bonkers S54 powetrain that has all the smoothness of a classic BMW I6 but actually wants to rev to 9,000. Combine that with the classic BMW traits of the door being at the perfect height for your elbow and the fact that this car is tiny! - my head hits the ceiling - and you have a vehicle like nothing else on the road. It's what I imagine it's like to drive a TVR with airbags and ABS.

All in all, I am so happy I took a chance on this forgotten breadvan, and I'm eager to correct its remaining ills to bring it all the way back as soon as possible. 

After selling my 996-chassis Porsche 911, I was pretty relieved to be done with the looming threat of bore scoring and a replacement IMS replacement to my existing IMS replacement. The fear mongering was pretty intense, from both fellow owners to individuals who own shops that service 911s. The makers of IMS kits are now suggesting that you may need to replace your original replacement, which is a big change from the "one and done" approach. And even if your car has no evidence of bore scoring, there are legions of enthusiasts who will say your car probably has the issue. 

I hate to admit this, but it got to the point that I couldn't enjoy the car. That being said, I didn't like it that much to begin with, so it wasn't all that heart breaking to see it go. So now, with this in mind and the 2001 Z3 M coupe in the garage, we move to the next persistent threat: rod bearings. In the BMW world, rod bearing replacement is the equivalent of IMS replacement for Porsche owners, but with perhaps less risk because your engine won't instantly blow up but rather slowly degrade.

When I got the Z3 M Coupe, there, of course, was not evidence of bearing replacement, so this was first on the menu. However, once the original rod bearings were replaced, it was evident they were in fine shape and could have remained installed for years to come. Should I have had them done? Well, most M car enthusiasts would say it's worth the insurance and comfort of knowing the job has been done, but I could have delayed the job and dealt with some other more pressing maintenance needs in the meantime. 

Regardless, the condition of the original bearings suggests a history of frequent oil changes and lack of abuse, so there's the silver lining - along with knowing I won't have to tackle this job for years to come. 

The M Coupe went to the shop this week for the long-awaited rod bearing servicing. As part of this, the engine mounts and oil pan gasket will also be replaced. Since I was waiting for both the title paperwork to come through and to avoid driving it without the bearings done, the car hasn't seen much use except for around the neighborhood. As such, one of the main concerns was how notchy the gearbox was. I'm happy to say, those concerns have all but dissolved after taking it on a meaningful cruise. 

The transmission became much easier to live with within 10 minutes of driving as the fluid warmed up; otherwise, there were no surprises with this car despite four years of inactivity. When I got to the shop this week, the front subframe had been dropped and in looking under the car, I was pleased to see how many OEM stickers were still present on parts; some, like the shocks, are original Sachs units that will need to eventually be replaced, but it's amazing how stock this example remains. 

The transmission notchiness could be explained by the fact that it had the incorrect fluid. In addition, the rear subframe is mint with zero popped welds. The engine internals are beautiful with no signs of metal shavings or any other damage. I will need tires but I knew that; otherwise, there have been no ugly surprises thus far.

It has been a long while since any updates have been posted here, and for that, I apologize. Like everyone else, there's 10 pounds of crap in a 5 pound bag, and that's my one and only excuse for the lack of posting. The most exciting news I have is that I've acquired a bit of a unicorn in the last few weeks in the form of a 2001 BMW Z3 M Coupe, one of a handful equipped with the snorty S54 inline-six and made rarer still for being a sunroof delete example. 

I found the car fairly close by in Silver Spring, MD on the ancient BMW message board, Bimmerforums. The seller was going through a few things lifestyle-wise that meant the Clownshoe had been relegated to the back burner, and was left parked in the driveway of a house he didn't own. Covered with a cheap car cover and not registered since 2019, it was clear this M Coupe was in need of a rescue, and after very little haggling, I agreed to buy it. The price was fair for a car that will need a fair amount of preventative maintenance to drive confidently, including rod bearings, rear subframe reinforcement, and shift pins in the gearbox. 

Just 678 S54-powered M Coupes came to the U.S. in 2001 and 2002, making it one of the rarer cars I own - but also slotting nicely into the assortment of vehicles all built in limited quantities, save for the E30. My 996 will be leaving soon, and that will freely up space and resources for bringing this forgotten Clownshoe up to snuff. More to come!
