Spark Plugs

I can't even believe that tomorrow will be exactly 1 year since my last post. So much has happened since I last posted I don't even feel like writing it all down. In summary, I ended up quitting my job and moving to California. I sold the 1974 XJ12L for what I paid for it some 6 years ago but I was glad to see it go to a fellow OJC member.

I took the XKE to the Jags and Wags event in San Jose hosted by Club Auto Sport and Paul from the J.A.G saw the corrosion on my spark plugs and said "They are probably welded to the head". This worried me so I ordered a set of NGK BPR6EGP spark plugs the following week. I soaked the plugs with some penetrating fluid and left it for a few days. I thought that stuff would evaoparte away but it didn't so I had to soak it out of the plug hole with some paper towels.

I took my wrench to 6A and it came out beautifully. No issues at all for any of the plugs. The plugs that came out were all Champion RN9YC. And it looks like someone had put some nickel based anti-seize on it. They all had the perfect "colour" except for 5A, which was a little sooty. But given that 6A,5A,4A all run off the same carb I didn't think too much about it. 

I too put some hi-temp anti-seize and gapped them all to 0.025 inches. Took about an hour to get all 12 done but it went like clockwork since I know my way around these Jag V12s now. The V12 E-type is much easier to change spark plugs on than the XJ12s, especially the fuel injected cars.
