Using non x5 M62TUB44 in my 4.4 X5
I have a 2001 X5 4.4 that jumped chain. so lets get right to the point, I found a low mileage 2001 740il motor M62TUB44 for a good price. Can this motor be used in the X5? I see alot of threads about this but they all turn into "why did you x5 motor break" and then discussions about that. I know the oil pan, windage tray, possibly pick up tube oil pan and front covers are different. so are the valve covers. but..... cams, pistons, rods, crank ect are the same block uses different part number according to real oem (not sure why) pass side head uses different part number (not sure why) but valves and everything in the heads are correct. might just be a casting thing extra bolt hole or such. Let Me know ASAP I need to get this motor soon. Thanks so much. I just need straight answers not more questions like why not just fix the motor in the x5 (its junk, 215K on it anyway.) |

When I was racing Lotus cars, I tried to use a Gordini engine in the Lotus. The head was different because it was a hemi-cross flow head and not a wedge on the lotus which is what I wanted, but the engine block was different because of 1 engine mount. So I ended up using the original block but with all the internals from the Gordini engine.

I've seen 200k BMW motors that are opened up and still have cross-hatching on the cylinder walls. Assuming your motor is toast is a bit silly. You have nothing to lose by starting the dis-assembly and evaluating your current motor.
To me there is no question... the M62 from the 540/740 should bolt up into the X5. I would be more worried about differences in the electronics and other systems that work to make the engine work. Beyond a little bit of DIY, there isn't any reason why the motor wouldn't work in an X5. How many miles on the used M62?

WELL CONSIDERING THE VALVES AND PISTONS SMASHED INTO EACH OTHER, WHY WASTE MY TIME TAKING THAT MOTOR APART. Also if you have cross hatching on the cylinders of a M62tu then there is something wrong those cylinders were glass smooth when new. but thats besides the point, the electronics is no different betweent he motors. I am only dealing with hard parts here. both are vanos. the new motor I found has 65k on it. so with that said, it makes no sence to take that 216k motor apart and do a valve job, timing chain, valves, all gaskets (head really isthe only gasket that would not be touched) and risk a possible bottom end problem in a short while. plus the down time of the car while all this is being done. |

Here is a statement by a BMW tech member on here called Killcrap. I`m not entirely sure it is correct but taking some measurements to determine the position of mounting points would be a good idea .
Quote , Yea they may be all V8's however that doesnt mean it will work. Did you know that the 540i and 740i 4.4 M62tu is not a plug and play direct replacement engine for an X5. Extensive modificiation would needed to drill out motor mount brackets holes, and a complete retrofit of the internal crankcase ventilation system to external one would need to be performed.

well the crank case system would be no problem as that would go along with the oil pan, and intake from the x5. i am not sure on the motor mounts though. most of the engines have all the holes drilled and tapped just the mounts are in different locations and orientations. I wish they would still come into this dealership we dont see those older cars anymore and its hard to look at them to compare before I drop some money on a motor. i found a few threads that this has been done but no concrete finishes. some start threads then never answer back.

Why not ask the person selling the replacement engine to measure from the rear of the block to the mount holes and measure down from the head gasket or up from sump/block gasket .

i tried that and to get pictures, they are a salvage yard and they dont mess with "engine swaps" like they put it, but I can gladly buy the motor. ha ha Just looked at a X5 4.4 M62 there are several motor mount holes drilled and tapped in side of block. If this is consistant with the other v8 motors they have the bosses for the holes are drilled and tapped, the different motor mounts should just bolt on if different configurations. At this point all I can tell the difference is this. X5 4.4 = no hole drilled through block under intake for "car" PCV system 4.4 car = hole drilled under intake for oil return line from back of "car" intake. this is really not a problem as this hole can be capped off and the pcv components under timing cover can be removed (x5 front cover will have to be used) but.... I would like to chat with someone that has done this before. It seems that you can put a M5 motor in a x5, so that config seems to work. but no concrete evidence on this swap yet

I would go for it . I`m sure I have read about someone doing the same swap and it sounds like you can handle it .
Good luck .

It's obviously not a direct 100% fit - so you've started waisting your time right now, just by asking about it in forum. If the valves are bent you just need to repalce the heads - there's nothing wrong with pistons for sure. It would be also a very stupid idea just to throw in some used engine, without doing some preventive sanctions even on another 10 years old used engine with 65 k miles - otherwise there's a very real possibility the pistons and valves in the "new" engine will have another rendez-vouz soon, due to the common timing chain failure. So the logical minimum even would be - new rod bearings - new chain (tensioners, rails) - new valve seals - new head gasket Otherwise you've waisted the opportunity to do it once the engine's out. P.S: And you always see a cross hatching on cylinder walls of M62 with alusil coating - that is the most remarkable point if you have to distinguish between new identical nikasil and alusil blocks (not TU related, but the first non-vanos M62 had both - nikasil and alusil coatings) |
