My 2006 project...

[williamx5]

Good day all!!

Well, I have another project going since my others are almost complete... The 2004 (better half's X5) is still learning how to shift... I'll be updating that thread soon after some more drive time... And, of course my 4.6is is going strong after only replacing the front driveshaft... I did finally find and replace the bumper support and got the bumper lined up... Gotta do a deep clean, polish compound, and wax... Take some pictures of the BMW fleet my son and I have for you all to see... I have the three X5's, one 540i6, and he has the 03 330i sport...

This one is concerning my latest purchase... The 2006 4.4L X5 with panoramic sunroof and tiny 17 inch rims... It looks odd!! Like a 3.0L with the bigger motor... Non-sport trim and base everything...

So, I got it for a steal at $2500, but I am not so sure I got such a good deal on this one, like the other two... I rebuilt the 04 motor, but I got it for $2000 and it had running boards on it already, and sport package stuff!!

I pulled the stuff to get to the valve covers... My son and I got the covers off and noted the exhaust cam on the drivers head was out of time... We pulled the chain cover and loosened the cam bolt for that one... We got the cam in a spot where all the valves were closed and proceeded to spin the motor over... It still felt like I was hitting something... I pulled the plugs and looked in all the cylinders... Nothing... I rotated the cam I loosened and it turned in both directions indicating the valves on that cam were not the obstruction... I also noted there was a squeak when turning the crank, but figured it was the belt still on the motor... Once I pulled the belt and still had the squeak, I knew the rod bearings were toast... Maybe even the crank bearings... So, why did just the drivers exhaust cam move? What caused the oil failure? The motor looks super clean, so I'm thinking something catastrophic had to cause the oil pressure to drop, and the owner didn't heed the warning to stop the motor until it did it on it's own... OR the oil pressure was good and something else got in the system locking down the bearing... I can't wait until my next few days off when I can pull the motor and open it up!!

I did a search, but "OIL" is too short and won't give just results concerning oil... OIL PUMP gives all pump related issues... OIL FAILURE gives all failure related issues... UGH!! Oh, CCV also doesn't turn up any results... Think my issue could be the CCV??

Pictures are to follow!! Might need a new photobucket account... Mine are about full...

Cheers for now!!
