The one you got, despite the high mileage, shows very well cosmetically, a credit to the quality of materials and components BMW chose.

I have 4.6 and 4.8 envy, because there is no substitute for HP but my find hit all the other boxes I needed when I was shopping a couple years ago: cost, nearly fully loaded option packages, NAV and relatively low mileage (78K).

One night recently I read a couple of very thorough DIYs on the guides and it looked like a pretty deep dive, even for a guy like me with a good deal of major engine DIY experience, just not with the M62.

DIY: Timing Chain Guide & Timing Chain Replacement

Good luck with the projects.

Mike
Thanks! Yeah, the timing chain guide job is definitely intimidating for a beginner, but I've done 6 of them so it's not as scary to me anymore. From a technical point of view, the only tricky part is the engine timing, everything else is just simple disassembly and reassembly. You just have to take your time, label/organize everything you remove, and cut the job up into small pieces to make it more manageable. I'd say it's more a test of patience than anything, haha.

Since this X5 has 213k miles, I'm going to be a little more thorough than I would be with a 150k mile engine, meaning I'll replace anything that isn't visibly new, like the water pump, cooling hoses, and belt pulleys/tensioners. I'm thinking of going with an upgraded all-metal water pump and aluminum pulleys, just to make sure everything is bulletproof. The previous owner did some top-end work like new intake manifold gaskets and new ignition coils, so I don't have to worry about those things. The transmission is freshly rebuilt as well, so I don't have to touch that for a while. I'll probably change the fluid in the diffs and transfer case just so I know it's been changed.

I have a shipping update on the X5 4.6— it got put on a truck Monday afternoon in Seattle, so it should be at my house on Friday or Saturday. I'm pretty excited to tear into it and start fixing it. I also got a really clean 2001 740i Sport shipped to me a few days ago, the owner shipped it to me to fix the timing chain guides so I'll be doing that as well.

I was actually wondering about how to place the X5 and the 740i in my garage, since one of my garage spots is longer than the other due to having a water heater taking up a bunch of space in one corner. I looked up the lengths of the two vehicles and it turns out the X5 is actually shorter than the 740i by a whole foot! The 740i is 196" long, whereas the X5 is 184" long.
