Hello all, just stepped into the diesel world with an 89 12valve. Thanks to this site I have already tackled the KDP, which was only hanging on by about 1/16th of an inch(whew). Truck has 212k on it I think. It belonged to my great uncle that was killed a few years ago and I was lucky enough to purchase it from his estate. Look forward to learning so much more from yall so I can honor his memory and care for the beast.
