Cleaning Fouled Plugs

Post by ahramin » Tue Apr 02, 2019 10:06 pm

I've got a couple plugs here that are almost dripping oil. I'm guessing that if I try to put them in the spark plug cleaner with this much oil I'm going to end up with a slurry of cleaning abrasive and oil. Is there a solvent that's ok to use? I can't find anything on the Champion or Tempest websites.

Don't overthink it, just clean them, use contact cleaner or princess aviation brake cleaner.

I love picking the lead out of C65/C85 plugs :)

Contact cleaner or brake cleaner and a good blast of shop air.

You're right that it will create a slurry if you don't get the oil out first.

Hopefully it isn't indicative of more serious problems.
