N62 Valvetronic intermediate levers

Hello,

I know this is E60 forum, I tried posting on X5 forum but no help yet. Please, if anyone can help it would be really appreciated.

Is it possible to replace the valvetronic intermediate levers on a 2006 N62 engine without special bmw tools and possibly the eccentric shaft? I know cam lock tool will be needed but thats easily available.

I have not removed valve covers yet to inspect. Engine runs terrible cold or warm and misfires.

2006 X5 4.8IS with 55,000 miles.


-Already replaced spark plugs

-Drained fuel tank just to be sure its not bad gasoline

-replaced all 8 coils

- replaced valvetronic solenoids

-CCV on valve covers replaced

- CCV pipes are in good condition


Help please

Yes , you can remove and replace the intermediate levers , and don't need the cam timing tools to do it .

Hello, This is fantastic news
Have you done this repair? I ask because I saw there was a tool to release spring pressure on the valvetronic intermediate levers .

I've removed and reinstalled the intermediate levers for better access during a valve stem seal repair . Having the special tool is nice to have but I managed with out it .. The important thing is to rotate the essentric shaft so the roller on the lever is on back side of the cam lobes when removing the levers . Then make sure all the springs are correctly in the v notch . When all the new levers are in , rotate the engine by hand and get a visual on each and every lever and spring as the essentric shaft's cam lobes rotate , that they are properly installed as your rotationing the engine , prior to installing the valve cover .

Broken lever spring

I know this is and old thread but desperately need help here. While doing a valve stem job, pulling on the tension spring to remove the lever for better access I accidentally broke part of tension spring that goes on back of lever. My question is If I'm totally screwed or can I replaced spring without removing cams? Thanks in advance.

Its doable . I dont think there is a need to remove the cams or the essentric shaft to replace the spring .

HI HF could you pls elaborate from what I can see the screw holding the remainder of the broken spring is facing in, I don't mind removing the valvetronic unit as a whole, I would only change the spring and put it back but to remove it you have to remove the upper cam sprocket. If there was something to hold the cam sproket in place where I wouldn't disrupt the timing chain at all. Thanks for any help you are able to provide.

Hmmm i was hoping you would be able to get a shot at the retaining screw . are you sure you cant get an angle on it from the other side ? Also at worse case , i think you can pull out the valvetronics out as a whole unit .
