I am using a small number of tools and I have bought the GM service manual for my model. I have removed the hood and was able to pull the engine with no major difficulties. It might take longer, but If you have another means of transportation and not much money, It is a good deal. I have decided to re ring it and replace all the bearings, seals, and anything else that should be replaced. I will post pictures of the engine and list the steps and information I have found. Any added info would be greatly appreciated.
pictures if you have them will be valuable to others.
be super cautious on the headbolts, the timeserts, etc ...
you didnt say what the mileage is on the engine .. rings and bearings may well be a waste of time and money unless there is something that you didnt mention .. normally these engines do not show any wear for the 1st 250,000 miles or so .. seals, i can see ...
best of luck
