I need to replace the head on my m50. Anyone know a good cheap one or where I can borrow one? Snapon wants almost 700 for it.

ebay.
I dont use one though. It's not much of a big deal to align the cams with a straightedge.

couldn't find one I needed on ebay, maybe I'm not searching the right words. Don't I need one to lock the crank? I'm not even sure what it does/is my dad is telling me to try to find a cheaper one online so we will have some more money for the actual parts.sigpicComment

I am not sure on a m50, But on Most DOHC head's the cam sprokets are close enough to each other that if you find a nut with a flared base the just fits between the groves in the cam gear at equal points above an below the the center line. then you take the correct size of threaded rod and set the nuts to the proper distance apart and put the whole thing in between the cam gears.

You can also get an inexpensive cam lock tool from catalystracing.net for $45 shipped.
You don't need to lock the crank, but you need to make sure the TDC mark is dead on.
Good luck with your head replacement!
You also need a timing chain tensioner. Usually you won't need the Vanos turning tool, but if you want to check Vanos travel you need the test fitting or make one from an old Vanos oil supply hose.

I did this last year. There is a guy on Bimmerforums that rents out the tool package for ~$40, with a ~$200 deposit. George Bregar was his name.
That ebay link had the dowel for aligning the crank IIRC.
All you need to check your vanos is 12v supply to the solenoid, and air pressure in the port the oil hose connects with the banjo bolt. Fairly sure the pressure needed was 40#, but doublecheck the Bentley. I just set the regulator on my air compressor, and wrapped electrical tape around my blowgun nozzle to make a decent fit.
Also, if you hook up the juice to the solenoid backwards, it kills the unit. It's marked on the connection as to which is "+" & "-".
The Hazet socket for the headbolts was more than the cost of renting Georges' package, and he included the headbolt socket, cam locker, cam sprocket rotator,timing chain tensioner, and a dowel pin for the flywheel to lock the crank.
Use a paintpen to locate everything before you take it apart, and putting it back together will be nearly idiot proof.
It's not how you handle the good times, but the faith you keep in the bad that defines you.Comment
