How to quit smoking

[dieselbenz1]

Ok I've been at this for a while 1992 124 602.962 I had a nailing and smoking problem at any rpm under load and no load. Checked everything in the fuel delivery system tried a different fuel source, pressure tested the fuel system. Replaced the head gasket nailing went away had a water and oil leak under the old gasket. Now it smokes under 1800 rpm no load and I mean smoke a lot not as bad a before the head gasket change. Ran moly purge no smoke at all. It idles ok could be a bit smoother as it once was. The nailing is completely gone. I change and balance the injectors before the head gasket no real change.

I'm now thinking maybe it's the fuel rail in the injector body. Could this be stuck to full fuel and how can I check that. Most of the codes are in error when I read the odb1 flashes.

Thanks
