Bought a cheap care $250 with 143,000 miles clean nice car other than a few years senior. The add said it was leaking coolent from behind water pump and was over heating. I figured I would take this project on and do the TC as I have done them before and felt comfortable doing it and had tools required. I drove the car home only few miles and when I pulled up the coolent just came gushing out the back of the engine. I used a mirror to look to see were it was coming from and all sighns pointed to top left corner of TC but could not see fluid coming out but could tell gasket was shot (looked like a lot of heat from Cat). Pulled TC and it had been leaking, the gasket was shot and brittle. Cleaned and replaced with new WP and Felpro for both, torqued all bolts as required and only dab of black RTV in the TWO corners only and the key slot on the dampner. Did the oil change and started filling coolant only to have the coolant flow from the back of the engine, was not coming out as fast but needles to say it was coming out as fast I poured. Started after the first gallon of coolant that I poured in. Should have done that before oil change. My question is, can I just replace the back head with a re-manufactured head with new valves and springs and a set of Felpro gaskets and head bolts or do I need to replace or should I replace both heads and bolts, will already have gaskets. AZ has remanufacted heads with springs and valves for only $191 each and I get VA discount so Thank you AZ. Should I just get two sets of heads and two sets of head bolts and a set of Felpro and few days of patients, pictures and parts and a few touque speaks. What else would I need besides cleaner and wire brush and paper towels. I know some will say why but I feel I am up the the challenge and this type engine should be good starting point for a newb but ready for next challenge in engines. Any advice would be greatly appreciated and any tips would be thankful and a link to Toque specs and pattern for reassemble of bolts would be much appreciated. Maybe a little confidence booster that this job is possible to be succesfully done by a newb. Thanks all.
