My water pump went out in my blacktop SR. motor overheated, but i didnt think it was that bad. changed the water pump, and ever since, it will run fine driving around 20 minutes or so, then the temp gauge creeps. no coolant leaks anywhere, but the coolant level is low. checked the oil and it IS a little milky. when we did the rebuild, we used a felpro headgasket. i have pulled the head to change the headgasket, because it is what the process of elimination pointed to. my question is, do you think the felpro was my mistake, should i go with a cometic this time.?? any other options.??
