| Post subject: | My First Slant Six Spark Plug Replacement |
I thought I would share my experience today - it was good. I have never changed plugs on a car with spark plug tubes before. I was a little apprehensive about oil leaks afterward. I bought a few sets of new tube seals from Summit Racing, Mahle GS33731 (PS69-B on the inner bag) - made in USA. There were no leaks when I started and I have no idea how old the Champion plugs were. Each tube came out with its tube seal in place augmented by some kind of sealant. That made me a little nervous as I planned to not use sealant. I carefully cleaned each tube so that its seal surface was perfectly clean with no sealant remnants at all and I carefully wiped down the seal seat on the head. I put the new Mahle seal dry directly on the dry clean tube. Also, I removed the spark plug crush washer as advised on this forum and elsewhere. The old plugs I took out had their crush washers on. I did not use a torque wrench (I need to get a good one) but slowly torqued each plug down quite snug. She fired right up and I let her warm up to full operating temperature. So far, fingers crossed, each tube seal is dry! I hope that continues. By the way I used Autolite AP66 plugs gapped at 0.035". Thanks all for giving me info on the whole tube seal exercise. Jon |

Sealant isn't necessary or advisable on the plug tube seals, so you did fine putting in the new seals dry; that's how they're supposed to be. Tune-up component suggestions (and rationale) can be found here. |

Thank you. I had not read that but it just did not make sense to me to put anything on those seals. |

Well, my success is tempered just a bit. After a couple of weeks I'm seeing a slight leak from the cylinder #4 spark plug seal - crap. I haven't had time to pull it out and inspect it. I hope I can get it to seal. If the seal is damaged I do have extras to replace it. Almost a success. |
