Hi - I've got a 1990 1.3 Escort. In the past 5 years of owning,every time I change the plugs, at least one of them snaps and is really hard to get out.So far I've always managed to get them out. I don't reckon I'm over tightening,been changing plugs in other Escorts for years and no problems. Today I broke 3 and I'm getting angry with them! I've put some copper slip on the new ones but a mate says it's a waste of time as the heat of the engine will burn it off. Any suggestions for next time?
Thanks,
Trev
