740il 4.4 timing marks

[kzoo]

Can any one help me with were the timing marks are when doing a chain replacement. Thanks

No timing marks: you need to use the series of special tools to lock the camshafts and crankshaft into place, then set the vanos.

Any more info on the tools?

and if it is a M62tu eng you will need a volt/ohm meter to set vanos also.

the tools he is refering to is cam blocks, they hold teh cam in place at the rear of the cam and attach to the head. the crank tool is a rod that goes into the flywheel, by way of a hole in the bellhousing to hold the crankshaft.

Then there's also the timing chain tensioning tool, and the cam sensor alignment tools (2). Total tool cost about $650-800 for the set. Year of the car?

I checked the tool set at my work today, it's made by Baum Tools/

Thanks for your help I was able to get the tools to lock the cam and crank but can't find any one with the inpulse (cam sensors pick up wheel) wheel line up tools. Does any one have a pic of these motors on tdc so I can try to line these up by eye.

Don't do it, man. Factory wouldn't have made the tools were it possible to do it by eye. Do you have the tool to tension the timing chain while setting the VANOS with your multimeter? Really, this job should not be attempted unless you're prepared to completely follow the directions, if you try, you'll likely trash the motor.

I have the all the tools for for the chain set-up but don't have the impulse wheel ajuster. From what I read this is how the ecm sets spark timing and vanos ajustment but has no effect on the cam to crank timing. So at worst it will not fire or run bad. If I could find the tool I would use it. All it is a hall effect and it is looking for openings in the wheel to see a square wave pattern. So there should be away to set it at TDC. If any one has a link to the tool or a pick of the motor on TDC. Thanks
