The vacuum advance is a different story, it is difficult to get the VA to work as designed with a turbo. set-up... unless you have a draw thru a carb. system.
You may want to go with a mechanical advance system only and get additional 'light load' / no boost advance with an electronic controller activated by a pressure switch.

Not true. I set my base timing at 20* and under light acceleration (non boost) and cruise, the timing is at base 20* plus the 12* vac advance. Under heavy acceleration, the vacuum advance is "off" and the timing naturally retards to the 20* base. This is with a blow thru.

You should hook the PCV up to the normal port on the carb. I've had no issues with it there. On my Buick turbo there was a place for the breather to be hooked up on the inlet side of the turbo but the pvc was
still hooked up normally.

Hi Everyone, I am new to both slant six and the forum thing but this looks like it could be extremely informative. I installed a volvo turbo on my 64 dart 225 and i am having issues with smoke in the exhaust. The system consists of a super 6 intake and exhaust manifold , a weber 38DGEV, MSD Boost timing master and a volvo tdo4 13G turbo on a 2.5 in exhaust if i hook up the pcv to the number 6 intake runner port the engine runs great with some very minor some coming from the exhaust, If i hook up the PCV to a port i created on the piping between the air cleaner and the turbo's intake it smokes like a Georgia mosquito fogger ( no offense to the fine people of Georgia). I believe the normal operation should have it hooked up to the port i created between the air cleaner and the turbo. ' I also have the vacuum advance hooked up to the same cyl # 6 port (Manifold pressure) so it advances once the car starts and retards when the condition changes to boost. Is there anyone out there who has installed a silmilasilmilar or run into a similar problem? Thanks

Welcome to the site. I know next to nothing about turbochargers, but there are a few people on this site that do. The only advice I can offer is here. good luck

Knowing that there was never a factory made SL6 turbo set-up, every turbo set-up you see on a SL6 tends to be different... that makes it hard to find any detailed knowledge base for your application. You should be able to control the amount of oil being sucked thru the PCV valve by the valve's type (flow rating) and position in the valve cover. Is the PCV mounted into a factory valve cover with it's baffels in place? The vacuum advance is a different story, it is difficult to get the VA to work as designed with a turbo. set-up... unless you have a draw thru a carb. system. You may want to go with a mechanical advance system only and get additional 'light load' / no boost advance with an electronic controller activated by a pressure switch. DD

I can see how it actually works to your advantage to have the 9 degrees pulled out of the vacuum advance when boost comes in. The only problem I can see is that it goes away pretty quickly. But maybe that is fine. I see from the u-tube clips I have watched of your car that it runs pretty well. Sam
