Hey everybody,

Quick question but not without a backstory.
First some specs:
1984 4d55
71k miles (could be 171)
Tc05-10a turbo with a waste gate
California emissions (California injection pump, egr, and all the other performance and economy robbers)
I am blowing smoke when I stab the throttle or maintain rpm (cruising but smoke at maintained rpm is intermittent).
At first I thought it was oil (71k and no idea on turbo history) but paid more attention and it looks like fuel, similar to the puff I get on a cold start when I have to crank more than once. It isn't black, that's why I jumped to oil first.
This only started after I put on an oil catch can (or separator) and does it with the can vented to atmosphere or connected to the intake. If I hook the valve cover back to the intake without the can there's no smoke cloud while driving.
Thoughts? Leaking injector? Pump timing?
I know very little about diesel injection pumps or tuning them but I get the gist. (solid gasoline automotive background)

Thanks in advance
