Can anyone offer any tips on changing plugs on 87 GN? I took the front plug out on the drivers side and for a couple of turns or so it acted almost cross threaded. It finally loosened up and I saw no damage to the plug. I reinstalled it with a little anti sieze compound. I heard somewhere that on cars with aluminum heads there was a special technique for removing plugs. I believe this engine is basically stock and did not think it has aluminum heads. Am I correct? Also the back plug on the passenger side seems like it might be a challenge. How do yous guys do it?
Thanks in advance
