Looking at getting a slant 6 rebuilt.

[Reloadhby]

My number 4 cylinder on my slant six rings are bad, inquiring here before I go else where on rebuilding the motor. It has mechanical lifters. My number four cylinder pushes gunk up in the spark plug and fouls it out but its still drivable. The motor is a 71 truck motor.

Got to put a none fowler on your spark plug most younger guys won't know what that is

Known people using these on almost every spark plug.

lol it runs and drives but my mpg in it has been cut from 20mph to 15 since it started doing that

Could just need a valve guide and a new seal. Had a Duster with that problem. Had the head reworked. Of coarse that was 35 years ago LOL.

Compression test will tell you if you need a valve job or rings or both. Do a dry and then a wet.

I picked up a Non-fowler and am going to try that for now, well see how it does

I put a Non-Fouler on my number four cylinder. It does run a little better, along with I made a 120 round trip drive today and it seems to be getting better gas mpg now. Not quite 20mpg like I was but about 17 or 18.

I did have to change the spark plug on that cylinder though. It was bottoming out on the Non-fouler, it went from a 36 gap to like 10 when I first pulled it out after putting it in. I run a NKG with a longer electrode but had to go back to the regular auto light.

I know what it is. Ain't seen one in decades but they work.
