1999 740il - OSV?

where is the osv valve on a 1999 740 il-and also is there a pvc vale on a 1999 740 il

The OSV is on the driver side behind the timing chain, right under the cylinder head.
PVC valve? Can you be more specific?

behind the timing chain? is that under the valve covers?---pcv valve is on american made older cars--

The PCVV (positive crankcase ventilation valve , AKA rear cover of the intake) #2 in the intake picture attached ,
the OSV (oil separator valve) # 1 in pic attached ,is behind the timing chain as described.
The pipe # 5 goes under the intake, if you will look down, under the intake, close to the throttle , you will see one end of it where connects to the OSV.

The PCCV is the one with the membrane that goes bad ussually.
What are your symptoms?

PCVV buy OEM, Non OEM last around 2-3 months if you have badluck. I had and I changed 2 + the OEM. Replace all the O-rings and pipe from OSV to PCVV.

blue smoke on startup---- just sometimes tho-----

Sounds like a bad PCVV. Around $ 100 parts and a nice afternoon.Or the worst case valves stem seals...
Good Luck!
