Sounds like your Packard is having simular issues as mine if you get a fix then it will be good to test for my 51. I'm guessing that the worst case I'll have to have a rebuild.

It seems like the motor may be a bit worn as in looking at the draft tube it pulses smoke out of the pipe at idle. I've been trying to just drive it and hope that things get better. Currently this hasn't been working well as it isn't getting better and I'm trying to get it to a point where I can trust the car on the road. I may need to adjust the carburetor too as in coming to a stop it may die out. Sometime it starts back up but there has been two instances were I needed to wait a while then eventually able to start up. I had the generator rebuild and am still running the 6 Volt positive ground system so there are mixes of enjoyment and frustration.

I'm continuing my restoration project and not only does it smoke a bit out the exhaust but also out of the tube coming from the side lifter cover. I'm guessing that this would be a bad valve seal and probably valve guides any suggestions on fixes or has anyone had this issue with their inline 327 8. I'm going to take off the covers and see where it is coming from but that will still not help on how to fix the issue.
