Re: Valve Stem Seals
The even # side looks good. The odd # ones look a bit encrusted with ash...a sign of oil consumption...with 3 and 5 the worst. If the deposits accumulate within a short period then you're looking at worn valve guides. Since you say they might be the originals, then that signals a slow deposition rate. You can replace the valve seals and see what happens...it's not an expensive job, just time consuming.

Re: Valve Stem Seals
Sounds good, Thanks guys!
I have been running on the new ignition components for a while and it seems to run better. I think I will go the winter like this and replace the valve guide seals in the spring. Unless for some reason it starts missfiring from fouling out a plug.

Re: Valve Stem Seals
Is it pretty common for 350's to have excessive valve guide wear?
And also, Marvel mystery oil in the gas tank? I was thinking about running it through the crankcase, and then seafoam or chevron with techron through the fuel system.

unburned fuel however with poor ignition componets is not good for the engine oil however then things do get worn/damaged. marvel added to the fuel at the rate of 1 OZ /10gallons of fuel will clean the entire fuel system, and also lube the combustion chamber valves and rings. over a few tank fulls it will gradually get smoother and quiet down the engine... this product has been around forever. I have used it in the fuel from lawn mower to my vehicles...this does work...the fuel componets made of metal can corrode , this product keeps them clean and bright... marvel in the oil at 1OZ/qt is good to remove carbon/sludge...also this product does not have chemicals that will damage the oil seals... my 1983 had 380,ooomi no leaks 17yrs original owner...marvel made this possible..with no engine work...the valve covers were never removed.. I used marvel however from day one ...so with that as a testing base I know it does work and is safe.
