After a few weeks of hard work for me, a couple of hours a day. I am disabled and feel very lucky to be able to get in a couple of hours of work a day. I'm just about finished up my first timing chain, guides, sprockets, and etc. I put a new water pump on, but used the old oil pump it was in such good shape. I pulled the front differential and took the oil pan off. The right side guide had started coming apart so I had to clean out the pan. I pulled the head and replaced it with a head I had bought on ebay and had a machine shop do a valve job and shave .006. Cleaned up everything the best I could and reassembled. She fired up but with a bad idle miss. Found the gasket that's between the EGR tube and air plentium that I half installed. I missed one of the bolt holes and the gasket swung down. Fixed that and it is smooth now. I can't thank this foum enough for the information that I have gathered here.
