I finished replacing my valve seals today, and am I ever glad that job is over! The reason I went ahead with the job is that I was having a little rough idle in the morning with quite a bit of blue smoke, which I figured was tell-tale of bad valve seals. What I want to let everyone think about before they do this job is to first install new injector seals. I did these as part of my valve seal job, and when I pulled the injectors I thought to myself "I bet this is the problem." The injector seals were leaking and when I pulled out the injectors, the barrels they screw into were filled with oil. Now I'm thinking that this is were the oil and rough idle was comming from. I could be wrong, and hopefully all that work replacing the valve seals will be helpful, but if anyone out there has what they think are symptoms of bad valve seals, my advice is to first replace your injector seals.

The other good thing about doing this job is that I found out my timing chain, at 148k, has NO stretch. Was very happy to find that out. If anyone has any questions on this job, feel free to email me.
