Hi, all. My 80 is a 94 with 158k currently on it. Changed my plugs last Saturday (October 28, 2006) and I thought they look good. I even compared them with pics from a link given by Cary on https://forum.ih8mud.com/showthread.php?t=117311&highlight=spark+plugs but not too sure about what I see especially that I was losing coolant. I had a leaking radiator, though.
These plugs (NGK BKR5EYA) were installed on June 28, 2005 and were 'subjected' to two long drives amounting to ~ 10K Kms.

Pic 2: Plugs 1, 2, 3

Appreciate any inputs. If anything, I'd like to know that I'm not burning coolant. As mentioned somewhere in the forum, it (ie HG) will be a matter of when but would like to 'postpone' that since I still need to save up for that.
Let me know if you need more info for a more meaningful diagnosis. Have a nice day.
Best regards,
Arnie
