As some of you know, I blew a spark plug out of my passenger side head the other day. The car had been ticking [sounded like an exhaust leak] for a week. It eventually blew the plug out before I figured out where the noise was coming from.
John [Shelby Guy] has done this repair before so he came over with the repair kit to fix the head for me. The repair consists of reaming out the affected spark plug hole, tapping the now larger hole and then inserting a threaded insert into the hole. The process was pretty easy and I was very happy when we threaded a plug back in there.
I had to run out to Dan's to get some new plugs so I didn't get much of a chance to try the motor. John and I threw a TR6 plug in there temporarily and started it up. It rattled for a second at start up and then everything smoothed out. I'd guess the gas in the cylinder dried out the oil around the rings or something and one revolution was necessary to lubricate it again.
After installing the new set of plugs, I started the car again. No rattles. Ticking is gone. I took it for a ride, let it warm up and then got on it for a couple of full throttle runs. YAY! Everything works perfectly. No bad sounds at all. Idle is smooth. Full throttle is smooth. Looks like the insert was all I needed. Thanks John! You are the man. :headbang:
