I am just finishing an engine rebuild and have used a bmw x5 engine as a replacement due to mine having damaged bores as well as timing chain woes.

The cause of these woes was a poorly fitted oil filter, po not me, it did not close the valve at the bottom of the filter.

As such my suggestion for an essential mod is a small manual velve in the drain of the oil filter. I used a ball valve so there can be no leak down of the filter housing unless i want it, this also means i can prefill the filter canister before start up on filter changes, again a usefull feature.
I had to buy a replacement filter housing as centre plastic bit was broken, it took three attempts to get a good one from a breakers, suggesting to me that this may well be the cause of numerous engine failures.

Now to engine differances, remarkably few.

Mounts, not sure if any differances, i used the rr ones though
Exhaust manifolds again i used the rr ones but the x5 looked identical.
Intake manifold, identical.
Wiring loom , x5 completely differant. Must use rr.
Sump again must use rr for both upper and lower.
Oil pump pickup again differant must use rr pickup.
Water pump was identical, although i put a new one on.
Everything else was identical, including pickups

are the cam / cranks the same ? a mate of mine once changed an engine in a voyager same engine numbers but the electric's were diffrent in the years, he had to then strip cam shaft and crank shaft replace them with the other's

Excellent info, thanks for posting, always wondered if the S62B50 M5 engine which is based on the M62 would fit... also the later M62B48 4.9ltr...

I hope I never have to find out...

Thanks again..  Pete

The s62 is a much more powerfull engine and is based on the m62, but it is not electrically compatible with range rovers or x5`s. It has two vanos per bank, intake and exhaust. Rr has one on the intake. And there are other differences.
The cams on an x5 are compatible with the rr, and if you choose a 4.4 as donor , identical.
There is a 4.6 which has a slightly bigger bore and longer stroke, differant heads and cams. But is physically compatible, and would run in the rr.
But a better choice is the 4.4 which subject to bits already mentioned above identical.
The car, as opposed to x5, engines are slightly differant in detail, the oil pump is differant to start, then there is the oil breather, ....., so its not ideal.
There is no m64b48, its an n62b48 and is completely differant. Alpine might have done an m62 4.8 but they will be very rare and not sure it was m62 based.

Oh, I know they would be extra work, just be something different... probably easier to drop in an american small block crate motor and run it on Megasquirt or similar...

Got the M62B48 info from here, mind you doesn't mean the info is correct....!!!!

Yes i looked it up. I was unsure alpinas 4.8 was an m62 engine. Wikepeadia confirmed it was.
But it was only used by Alpina, in my defense i did say alpina may have made one......
Any bmw 4.8 you see listed will be the n62 engine.
On a more important note it is not compatible with the rr as it has vanos on both intake and exhaust cam, like the s62. And it has too much horsepower for the rr gearbox, which is already pushed past its design limits by the 4.6. Not sure what box alpina used i assume the better 6 speed box, or a manual. I may be wrong though as i am guessing The one we all wish we could drop into the rr!

There was an ‘035’ version of the ZF 5HP24 transmission which was used in the Alpina B10 (E39) and the Z8 Roadster (E52) but I think these may have had the 4.6 engine still, and not the 4.8?

Only 776 of these transmissions were manufactured in total, between Nov. 2001 and July 2003.

Hi phil
Did not know it was that few manufactured. I suspect they where not much stronger though as there where only a few differances. That and the reported levels of gearbox problems in 4.6 x5 applications.
I do know you are the expert on these however.
But i am interested in your views on the relative strengths.
I do know zf blame bmw for the failure rate, some software issue.
I beleive you can get the gearbox software upgraded by tuning shops, i am interested to know what the actual issue zf has with the bmw software, perhaps with a view to getting it softwared out.
I think i may have just invented a word.......

From what I can tell, the 034 and 035 transmission hardware is identical, beyond the obvious 4WD vs RWD differences.

Interesting.
I do wonder what the best changes would be, and what changes would be prudent in the gearbox software.
I had heard zf did not approve of the speed of gearchanges and the amount of slip bmw programmed in to make it softer and more rolls royce ish, for want of a better description.
A number of bmw tuning shops do offer gearbox ecu programming, hence the ruminating.

Yes, I notice that a lot of people on the American BMW E53 forums bang on about 'Dinan' transmission software upgrades on their 5HP24s : http://www.dinancars.com/products/?series=...ine-tuning
