Thank you so much for your much appreciated reply. I am about to go and by the parts and the pressure gauge tester and gasket. I will kepp you posted on my findings. Back in 1997, I bought a 1988 Astro Van which had the eengine rebuilt at 125,000 miles. I bought with 130,000 miles on it and the van lasted me till 2006. I took the engine out to put it into another van I bought. When I first bought it, I always took it to a shop, but after spending more than 5,000 in repairs, I began to do my own work. My wife has a few family members which are mechanics which I began to hang around them and I picked up a few things from them. I saw that patience and the proper tools played a huge role in fixing a car. So I began to buy tools and books and then I got greasy. So yes, I do have the experience and patience to do the repairs I can do. Well, I will keep you posted.
