My car is 67 Mustang with the 200 six. I'm hoping to get some help from the six cylinder experts here.
My car is in nice shape, runs good with no smoke. Has good compression. Will oil foul the #3 plug quickly. Develops a miss I change the plug then repeat. I was thinking it may be an oil seal but they look ok? Not sure exactly. I see no rips or missing pieces. I did notice some are shorter than others. Some of the valves are red around the heads? Not sure about that one.
I should mention I have tuned it up and rebuilt carb within the past couple weeks. Seems all good except for the #3 oil fouling...
Thanks for any help!
