I had no idea you could put those things on upside down! Did you drive it that way, or did you catch it before driving it? As far as not worrying, I’m not sure it ever stops. Even after 20k on some of these parts I rebuilt, I still hear every squeak, knock and other noise and wonder if it is the diff, xfer case, motor, etc. coming apart. It’s funny how I never thought twice about this stuff when I had/have a shop do the work.

I didn't drive it, but did roll it around in the garage. It could have driven, sort of. The steering wasn't going full lock. Something was up but I wasn't sure. A few days later I eventually noticed the nick mark on the control arm where it was contacting the tie rod. The ball joint end goes downward through the knuckle, not up.
![]() 300 miles in and I think it's okay. I put a spec twin disc on this one for some reason, not many options. It's chattering like crazy out of first still. I think I've had two smooth starts. Not sure how this is going to go. I previously had the 550 clutch which was very nice but it didn't last and wouldn't hold the e50 tune. This was supposedly the best option. I might be 0/2 with aftermarket clutches. The uuc one on e53 is nice but I cannot avoid smelling it, especially reverse. I don't think it is going to last either.

Busy work on the E53
I decided to buy a new oil pump for the 4.4 rebuild, which arrived from Getbmwparts last week. I have a gently used E53 version of the M62 oil pump I'm happy to contribute to someone's cause, if needed. The AWD and RWD pumps are different. Also coming in was 8 sets of new M64TUB44 Mahle piston rings that I grabbed from FCP as they popped up on clearance. At this point I have everything I need on hand to rebuild the bottom end of the 4.4, except two of the 4 thrust washers needed for main bearing 5, and the bottom end of the 4.4! Its at the shop still with the crank getting cleaned up. Hopefully this or next week it will be ready. He did mic it and find one cylinder slightly beyond tolerance (oval), but I'm going to rebuild it anyway and see how it comes out. The guy said to me that he wouldn't have thought twice about the measurement or even have told me it if I hadn't given him the specs. Hopefully new rings will make a good seal.
I had some time off this week so decided to tackle a few maintenance items I'd been putting off because they involve coolant, power steering fluid, and messes generally. My X still has the OE steering pump reservoir in it and I figure the filter in the bottom of the reservoir was long gone. The pump was a "rebuild" rock auto LUK pump I decided to use during the swap because it was dirt cheap and not a terrible job if it only lasted a couple years. I've also been getting a "check coolant level" warning intermittently that seemed to indicate the sensor in the bottom of the tank was going bad. The tank is only a year or two old, but I reused the OE sensor when I did that job. Finally, my left front headlight has been fogging up after heavy rain, or a wash-job. I suspect the sealant has failed between the cover and the housing, but since I don't want to to tackle that job yet, I have a replacement rubber gasket (PN 63128386711) that popped up on clearance at FCP many months ago that I figured I'd try. All this stuff is easier to do with the left front light out of the car, so I pulled it. The new gasket popped right on and I did notice several breaks and tears in the OE one. Small, but perhaps they were letting water in. I have noticed what I think (hopefully) just dirt and grime on the inside of the lens cover, so eventually this will need to be addressed by breaking them open to clean/polish, and resealing them. ![]() ![]() Next up, I unbolted and drained the coolant tank from the hose to the aux pump of as much coolant as I could. Of course despite thinking I had gotten every drop, there was plenty left in the tank to dribble out onto the motor when I pulled the small bleed hose to make room to access the bottom of the tank. The "new" level sensor is of a completely different design than the old one. In fact, I initially thought that some plastic bits broke off the old one and were stuck in the tank. Nope, it was a bare wire design while the new one is entirely plastic. ![]() The old one pops right out and the new one fit perfectly. No gaskets or seals, because the sensor doesn't touch the coolant. Thanks to the forum for this info. ![]() After this I moved the tank over towards the motor and out of the way so I could loosen the reservoir and pull the larger line from the bottom and drain it. That little tank holds more than it seems it should...or at least more than a small mardi gras cup! laurel and hardy mess ensued as I tried to plug the outlet with my finger, while dumping the cup into a larger cup I had on hand. The good news is that the connector for the ABS/DSC pump is directly below the reservoir, so it conveniently fills up with Dextron III. ![]() Once cleaned up with half a can of electronics cleaner and compressed air however, it was easy to pull the other line and yank the pump. The new one pops right in, and seemed to be slightly larger in diameter than the OE one, as judged by the clamp that I had to loosen fully to make enough room for the reservoir to slide down fully. Its interesting to me that the 4.6 I swapped in 3 years and roughly 20k miles ago has sprouted minor leaks from the vanos seals, one of the valve cover bolt seals, and the front diff. The diff is likely my fault as installing this while the motor was in the car was a huge pain and I suspect I nicked the seal between the oil pan and the diff. All are minor however so I've cleaned them up and placed them on an "ignore" inspection schedule. It is a bit frustrating to see that the valve cover on the left side is already showing pitting and corrosion under the paint. I was in a hurry when I swapped the motor in so I elected to not have the covers powder coated at that time. ![]() At any rate, so far so good after logging a few miles on the car after the work.
