Take a look at these spark plugs

Take a look at these spark plugs - 10/20/12 02:37 AM

As i took off my headers i pulled the plugs and they all looked like this one in the photo. The plugs have maybe 1000 miles on them.

What do you think, they have a very hard coating on them almost like cement stuck to them.

Hummmmn no real smoke at start up and no real bad oil usage. If you stomp on it there will be some out the pipes but not anything terrible.

This is the original engine to the car so it's 43 years old.

Oh and i have been running 100 octane as well as Seafoam gas treatment if that means anything??

maybe seafoam is cleaning up pistons and valves and it is sticking to your spark plugs?

Interesting observation as in the past on start up the engine always a little upper end ticking for a few minutes untill it warmed up and now that you mention it the ticking is gone.

Well at 43 years old the valve seals are either gone / rock hard or

Next get a decent compression gauge and go to town and right down the #s

The hard whitish deposits is from the seafoam. Most all gas treatments will do that because of the additives..I would burn the rest of the gas in your tank and clean the plugs. Recheck the plugs again in another 1000 and see if they look better..the black deposits look like its running a bit on the rich side...

Does that plug look 1/8" too short is that just me!
Put a set of RJ12YC's in and try tha! I'm pretty sure that you have the wrong plugs I think what you are using are for a 1941 ford tractor

Im using and have been using these Accell #8197 spark plugs that are a better fit when using headers that any others i have tried in the past. The engine starts on ome key turn and runs perfectly. So this coating of crud is what is me. Thought maybe it's the brand fuel i use but i only put in Chevron 91 as that's the best we get out here.

It sure looks like oil to me most likely coming in from the bottom of the intake gaskets or the valve guides.
Stu if you lived closer we could have the next Moparts party engine rebuild cookout

Gus one of the things i have seen from the day i bought the car is a puddle of oil constantly in the valley of the manifold on the driver's side only though...Any thoughts on that?

Also here's a shot of inside the header tubes. They look like brand new with no a bit of discoloration in the last 10 years of use.

Does tell anything about the fuel mixture or oil usage problem??

Thanks
Stu
