I have a 98 12 valve that I bought new. Article I re-read in TDR from a couple of years ago concerned me because I had thought my dowel pin was OK. I ordered the kit from TST and gave the job to a long time trusted shop. The dowel pin had started out. Once again I had been saved by the TDR Magazine. The use of other vehicles available has kept the milage low 130K. If it had started out how much further could I have gone without flying pieces of my engine landing in the next county. Switching subjects. The best thing I ever did was to buy the conversion kit from EGR (in 2008) and now I have Disc brakes in my rear axle. Huge difference. Stopping distance is about half of what it was. Expensive but worth it. A fender bender with injuries could mean a law suit. So I consider it cheap insurance.
