what camshaft is this?

[pjoyaux]

Hi, i've got a spare camshaft- looks like it's never been used?  How do i identify what it is?  I see #2378 stamped on it along with BMW.   Any ideas?  Thx, Paul

Hi Paul

 

Looks like a stock cam at quick glance.  The stampings you show are manufacturing marks, not indicative of the grind.

 

Are there any marks on the nose?  Measure the base circle and lobe height with a caliper, that'll tell us the lift (which in turn will tell us if its stock or something spicier).

What Number ist stamped on the flange of the cam sprocket?
1,2,3 or 4?
1 and 2 = Standard
3= 300°
4= 324°
And it is used.

After a second look at your cam I came to the conclusion that yours might not be an OE BMW Cam is the casting os so crude - so you will have to measure

Additional bit of information to the above - it is for points ignition so likely a 2002 cam.

Lobes look std but hard to be sure.  And yes it's been in use, you can see the shiny areas on lobes.
