Wanted to post this here for all you small block experts... 190kish on engine, finally got these out after lots of soaking and a 30'' breaker bar or they would have been changed a long time ago.

Please let me know if you see any issues I should be aware of, thanks!

34 views and no comments? Do I have anything to worry about here? I want to run this engine for a good long while and I'm not sure what to think about the deposits...

thanks!

 

I see nothing wrong with those plugs other then they are very worn out. A fresh set of plugs of the correct type of either Motorcraft or Autolite brand will do fine.
The plugs do look like there is some oil burning but not so much that they are black or worse, wet! They look good for an engine with 190K miles on it.

 

Thanks for the feed back! May I ask what looks like burning oil? The black ash? Or what in particular?

 

Nothing to be worried about. Any engine with that many miles will use some oil. Yes it's the black ash but there's not much and it looks like it flakes off and goes out the exhaust so there's no build up.

 

They look very good to me also!!!!!!!!!!!

 

Thanks!

 

That's excellent close up photography.
The plugs look excellent, I'd try gapping them and reinstalling with neversieze on the threads. Maybe give 'em a few swipes with a tooth-brush size wire brush.

 

They look good! worn out but the color is good. for 190K I'd say the engine is doing pretty good by looking at the plugs.

 

Thanks for all the replies! Glad to hear things look fine at least combustion wise...

 

Back before we became a throw away society we would have put them in a spark cleaning machine and gapped them. Anyone remember those machines?

 

We had one of the Champion Spark Plug cleaners at work, and when we recently were cleaning out old stuff it went to the junk. Well I think someone rescued it for home.

I used to clean plugs regularly when I was driving old cars that would foul them pretty quickly. The 18mm plugs work pretty well, but the smaller 14mm ones can be tricky to get all the beads out of the narrow crevice.

 

They disappeared around the same time the "U-Check-Em" drugstore tube testers went away.

 

There are probably a couple generations of people who don't know what those are.

 

I used the tube checkers a few times, a $2 tube and your TV worked for another 10 years..
