6.9 glow plugs

Some people believe the swelling could be due to people running a push button setup and running the plugs for too long. On my 86 that could have easily been the case as it had a push button on it and 5 swollen autolite plugs. My 93 however had and still has a factory controller and I removed 3 swollen autolite plugs from it when I got it. I took the few good autolites from the 86 and hooked them up to a battery charger. One of them glowed for about 15 seconds then burnt out, the other two swelled up right before my eyes. The quality control may have gotten better since then, as the plugs I pulled from the 86 were likely installed in the mid 90's and you don't hear many swollen plug stories from ones that were recently installed these days.
