Spec X5 Overland Build

[Henn28]

I was surprised too that BMW still offers new M62s for sale, much less the 4.6, which I think was a much lower volume version and used in far fewer cars? I bought it from BMW, via GetBMWParts.com, which I think is actually BMW of Silver Springs MD, cleverly disguised as a discount OEM parts biz. They had the best price on it by far and required no core charge.

Its been slow going for the past few weeks due to the recent storm here in Louisiana, and my work schedule. However, I did get a chance to get to the garage and unpack the motor and get it on a stand. It was my first look at it out of the box and I'm happy to report that aside from the crank hub, water pump and other misc. bits, it also has spark plugs and the oil sensor in the pan installed. The thing was sitting in a couple of quarts of oil (it was packed in a very heavy plastic bag) which I suspect leaked out during shipping and was a preservative they sprayed on/in the motor when BMW assembled it in 2020.



My plan is to install the coolant pipes and manifold as soon as the knock sensors arrive that forgot to order. Then I'll turn my attention to the front and get a rebuilt Bosch alternator and possibly a new power steering pump to go with all new belts, hoses, oil separator, etc. I am thinking the only big stuff I'll rob from my 4.4 are the front diff and the entire fuel injection set-up as one unit. I am thinking I can do a pressure test on the coolant system after I install the engine and before I put the manifold and injection back on the valley.


On another note, I've spent a little time laying out and understanding the wiring for the Kenwood radio upgrade I'm installing. Fortunately everything is pretty much color coded, and/or Crutchfield's excellent customer support is just a phone call away. I am waiting for the back-up camera I ordered to arrive and a few misc. parts before I start pulling the inside apart to finish running the satellite radio/camera wiring up to the dash.

Wow, that's incredible. Sadly it looks like the N62 is fully discontinued, but sure enough there are brand new M62's available to buy.

Sounds like a backwards swap is in order!

For those running bigger tires and wheels than stock, and lifts too if present, I’d be interested to hear about your fuel mileage experiences. I’ve been getting about 13.5 mpg around town here in New Orleans. It’s been several years, but I seem to recall getting around 15 mpg around town on the OEM 18” set up that came on the car. It does have 150k on it, but I’m not sure that matters with fuel economy?

I was planning on jumping into my wiring harness for the stereo upgrade later this week, but my wife’s 2015 Grand Cherokee (80k) decided to develop transfer case issues yesterday. When shifting between P, D, and R a distinct and rattle or knocking is heard from the T-case. It continues at low speed until, I think, lockup happens. I unplugged the electric motor on the transfer case and the noise disappeared. Next step I guess is to remove the motor but leave it plugged in and see what happens. Fingers are crossed that it is only the electric motor.

I get about 1 MPG less with the Falken Wildpeaks on (17.0 MPG mostly highway vs 18.0 on all-seasons).

Surprisingly, refreshing the suspension improved fuel economy quite a bit.
