looks great, but needs an additional part...

There are plenty of suppliers that make these for circle racing, and I've seen a few on street/strip drag cars that used a separate transmission cooler ( didn't need one on mine, as it was mounted behind a headlight bucket, after I replaced it with a dual hi/low lamp, but still used a light mesh screen to prevent a bug build-up).

While driving since 1965, I've had a billion stones damage my vehicles, a lower radiator hose and later, a radiator, pierced by road debris. “An ounce of prevention is worth a pound of cure.”

I’ll see if CSF makes anything for it. Thanks for the tipper.

Lights and clamps showed up and I had a few minutes to bolt them up. Initially I envisioned them hanging down from the bar, but I think this looks better, and I’m not sure they are weather proof installed upside down.


Next job is to wire them up.

wiring complete

I'd procrastinated enough so between rain storms today I wired up the KC Rally 400 halogen lights previously installed. They are 4" lights, which I felt would be plenty, and not overly out of place on the X5, but they may be a bit small. Fortunately the hard work is done and swapping them out should be easy. I like the 4" lights as the bodies are powder coated aluminum. Most other 6" lights by KC, Hella, etc. have plastic bodies.

My initial thought was to have someone 3d print an insert for the ashtray that would hold a rocker switch and the two USB plug ends to/from the audio head unit that currently terminate in the ash tray. A bridge too far for my one brain cell. Fortunately the switch that comes with these KC lights fits perfectly in the cigarette lighter frame, once it is drilled out.

The wiring harness for the Rally 400 lights doesn't have a relay (initially I thought it did), but rather a 15 amp fuse in line. The harness has a convenient plug in the middle so I was able to route and plug in the lights, then route the other half of the harness from into the car via a convenient hole (plug had long ago fallen out) next to the hood latch cable firewall hole.

Staying on this side of the car allowed me to connect directly to the battery at the terminal post by the brake booster, and the negative jump terminal by the oil filter housing. Then it was just a matter of plugging the two halves of the harness together and doing some clean up with with zip ties and wire conduit. I ran the wires out of the cowl at the rubber plug on the left side that allows a large wire bundle and the hood cable to exit into the engine bay. Still a little clean up to do with the routing and tiding up under the hood.

(wire conduit cleans it up somewhat, but I need to sort out that ugly power wire. Its not quite long enough so I will splice in a longer length and route it out of the way I think)


Pulling the covers under the steering wheel and the carpeted cover along the tunnel allowed me to run the harness up to the back of the cigarette lighter and make the connections. with the bottom of the metal housing completely drilled out, the 3/4 switch and 3x connections fit nicely.


They are on a hot bus right now being wired directly to the battery terminal. the switch lights up though when the are on, and I also ran a wire to the passenger side cigarette lighter (which I think is switched power) so I can more easily wire a relay in if I want larger lights or the added protection of no power with the ignition off.

Nice!!
Have you considered the LED lightbar for in between the KC's?

Insanely bright and almost cancels shadows when in line with the bar.

I went cheap! Halogen’s are super cheap, and I thought I liked the smaller 4” look. I might end up going with 6” lights in the future, but will live with these for a bit to see how they do.

Nothing wrong with that and it looks good with the KC's. I never looked at the cost for the bars, I'd only seen them turned on and could damn near see my whole skeleton through my body at a desert trip so that's why I brought it up.

The X5 is running strong and (knock on wood) has been a reliable daily driver again. I've got a plenty of "nice to have" stuff I still need to do to it, including trying a 90deg MAP t-stat, reupholstered seats that need to be installed finally and a blower motor R&R that will be nice, once the job is done! No hurry on this last one since it is OK when its warm out but screeches like a cat when the temp drops.

So I finally had some time and energy to begin tearing down the M62TUB44 I took out of the X5 today. Initially I'm interested in seeing if the bores looked good, or were scored. Thankfully my untrained eye tells me that they look good. I've got what look like wear on the walls where the (skirts maybe?) have made 150k miles worth of contact, but other than a slight discoloration, I can't feel a thin with my fingers or nails. I've seen some pics of scored bores on this and other boards, and thankfully I think I missed this problem, which will allow me to proceed with a rebuild. My plan was simply to scrap the motor if a bore(s) were trashed.

The motor has been sitting for close to 2 years now (time flies) and was a terrible greasy lump when I wheeled it into the corner of the shop after the swap was complete. I preparation I watched a couple videos on timing chain and head gasket R & R, and figured I'd take lots of pics, bag all the small parts, and see how it went. This will be my first motor rebuild (assuming I don't find any show-stoppers), but the teardown went very quickly.
From this:

To this in a couple hours:

I pulled the accessories first and while I had already robbed the AC compressor and accessory tensioner for the new motor, I tossed the power steering and water pumps, and hung onto the balancer, pump pulleys, and rear manifold and coolant pipes. I was pleasantly surprised at how clean the coolant passages were.



Next I pulled the valve covers, pried out the vanos seals out, and pulled the front timing covers. The covers are a mess and I'll need to evaluate if they can be salvaged. I've already noticed the covers on my new motor are beginning to "bubble" in a few small spots too. Not sure if this is the magnesium, or paint, or what?

Then I pulled the chain tensioner and got enough slack to work the chain off, which is good because I need to buy a socket big enough for the VANOS solenoids. I did first loosen the large nuts on the intake cams thinking the sprockets would slide off and I could get the chain off that way. Fortunately enought he tensioner removal created plenty of slack. The bottom cover is still on, but the parts of the guides I can see look to be in amazing shape considering the car had 160k on it, and i never changed the tensioner. Nor, for the 5 years my kids were driving it was I all that great about changing oil at my normal 4 to 5k interval.



After this work was done it was quick work to zip the head bolts out and pull the heads. Again, not sure what I'm looking at, but the valve train seems very clean while the combustion chambers, like the piston tops, have a lot of carbon build up on them.


As an aside, the block still had a lot of antifreeze in it (green, I'm ashamed to say!), so at this point I pulled the plugs on the either side of the block and drained it all.
Next up I inspected the head gaskets for signs of leaks, blowby, etc., and they looked good so I turned the motor over and looked in each cylinder. Happily they all looked great, to my untrained eye. As I said, I've seen pics of alusil motors with bore scoring, especially the M62 woes in this respect, but they look good to me.

Below is an example of what each cylinder looks like. I've circled the discoloration (slightly blue, maybe?) that is in each one, often on opposite sides of the cylinder, but where I can not detect any variance in feel with my finger or fingernail. All the pistons, and combustion chambers look like this one....lots of carbon build up.


So I'm going to call this a win and plan on rebuilding this motor to put into something fun eventually. I'm still noodling just what sort of rebuild to do (M60B44, or just stock), so more to follow on that. Frankly, I've not had too much luck finding M60 heads that aren't cracked, etc. either so maybe I'll just rebuild a stock M62TUB44.

This project will be a slow burn, so I'll likely just tack it onto my X5 overland thread, if anyone is interested at all. Next up is to buy a vanos socket so I can pull those solenoids and a crank hub tool to hold the thing so I can try to get that monster bolt off.

I used the stock wheels/tires as 17x7.5 et 40 wheel with 235/65/17 tires and 18x8.5 et 48 wheel with 255/55/18 tires.

Here is what I found... (Note: The info here is the best that I could find, but I can't guarantee the accuracy because, well you know, its the internet)

Example 1
18x8 et 13 Hamann HM2 wheels
Hankook RF10 265/60/18 tires
Poke 33mm more than stock
thank you so much for posting this. I just found a set of HM2 18x8.5 (tho the spoke shows 8 1/1J x 18, so I'd have thought it was a weird way of saying 8" width)...anyhow, after searching if they fit an E53, I come across your post and decide they should fit my 4.4i with 4.8iS front brake calipers... and yes after test fitting them today, they fit so I snatched them up. damn near MINT from a 2003 Land Rover, for $500 Canadian. still clean! Previous owner cared well for his vehicles!!
So, thank you again for all your wheel/tire examples!!

I just bought new 265/60R18 Nokain Outpost APTs too. LARGE diameter 30.5" but I should only have wheel rubbage at extreme wheel turns.
