    My 350 in my '89 has some miles on it, and its starting to get the "blue smoke" start ups. Does anyone know of any additives or anything like that I could try with my oil to help prevent this?

    I have had good luck using Lucas oil additives. To go farther into your isuue, I believe that you have leaking valve stem seals. Replacing them is not a big deal (takes a few hours and costs a few dollars) and will probably cure your problem without the need for a viscosity improver...which is essentially what you are asking for.

    Yeah I took a look at the Lucas products and have heard many good things about them.

    Now about these valve stem seals... this isnt a very difficult procedure? What does it basically consist of?

    I will second the Lucas products. They have worked good for me.

    If you haven't replaced valve stem seals before, get a manual. You'll have to rent/borrow/buy 2 tools. You will need an adapter to plumb compressed air into the cylinder that you are working on to keep the valves from dropping down into the cylinder. You also need a valve spring compressor. One at a time, take each valve spring loose and replace to seal on the stem of the valve. It will either have Oring or umbrella type seals. If I understand correctly, you can run both at the same time for better sealing a longetivity.

    I had the same problem on all my trucks. I started replacing a half litre of engine oil with tranny oil during changes and it actualy helped with the problem. Seemed to resoften the seals. Call me crazy.
