WVO did not do this. Mine was frozen and only ran pump diesel at 180k. If I had all new ones I may change them every two years as long as they broke free. I had one stuck and snap off after soaking in PB blaster for 3 days. Its the worst part about this car, otherwise I love it.

I dread the day when another glow plug light shows up. I have 189k and I think they are original as well (5 left). I am in the mind set of if it's not broke don't mess with it right now.

Sorry for your luck
