Ok, so the supra I picked up I got a new thermostat in and I got the starter in. Now there is that milky residue on the oil cap, but the oil on the dipstick looks fine. The guy before me had the head resurfaced he said and put back togeter. The old gasket and stud boxes were in the car when I bought it. I am wondering how to get the valve cover off to see if I can retorque it. I think the gasket might be good and it didn't seal properly? There are bubbles in the overflow bottle and I do get a code 52 Knock sensor if I rev it up passed a certain point. I take it this is a knock caused by the combustion of water and antifreeze in the engine? My buddy said I should have a full diagnostics done on it, but I am not financially graced. If someone could point me to a detailed guide on how to disassemble it to get to the studs and retorque them. I would be very grateful.
