Just rebuilt, started fine ran great for the first 5 min, then cut off. Won't stay started by itself and alittle milky in the oil. Builder says run it for 45 min. and see what happen's and we'll go from there. Drivers side heads is leaking alittle antifreeze, builder say's run it. Has fullthrottle 202/208 cam and seems to be running hot, around 200+, with coolant circulating as it should. What do you think? Could the head torques be wrong or felpro 9441 head gasket gone? Not sure if I should take it back or do it myself. Cars been down hakf the summer getting motor done, wanted to get alittle fun out of it. Is this normal for breakin? Need help ASAP or I'm gonna short block it this weekend.
