I did a search and every thread I found had too much stupid crap in it so I'll just cut to the chase. I have an '03 Vic and it blew out the #3 plug, destroying/melting the COP boot. I got the COP off and tried to tighten the plug but it just keeps spinning. I keep getting mixed reviews on the heli coil stuff, some say it may not work at all while others say it's a miracle cure and even others say it will eventually blow out too. Swapping heads is really not an option, I need this car back on the road by Monday and don't have all day Sunday to replace the head, nor do I want to spend that kind of cash. So, what's the verdict? Which kit is the best to use? I may just end up renting the kit from a parts store so I may be at the mercy of whatever they loan out.
