UPDATE on the glow plugs...

Hello all,

The glow plugs were switched out yesterday and it runs like a champ now. It started quickly before, but now I barely touch the key and it fires up.

I took a look at the old glow plugs and it turns out they were probably original (there's 195K on the car). So... their demise might have been hastened by the BIO-D, but they were on their way out anyways, there's really no way to tell...

I've had everything else switched out but the IP rubber. What should I keep an eye out for there if there is any BIO-D deterioration?

Thanks for all of your help everyone
