Default Re: Rear main seal or heads gasket? high temp!

If your car feels fine, coolant looks clean, no loss of oil level, exhaust normal, fan turns on after a few minutes and you changed temp sensor, and it reads way to the right hot, then you might want to try buying an economical temp gauge at autozone under 20 bucks, unplug stock gauge wire, connect new one to the temp sensor, and check the temp on the new gauge"you can just hold it in your hand", I was running super hot so i thought, the new gauge never went over 200, fan kicked in right at 200, where as the stock gauge read about "L" from NORMAL, near red when the fan would turn on, Bad gauge much better than blown head gasket. Stock mustang gauges are notorious for failing, I mean does your oil pressure gauge actually move, im working on a water temp, oil pressure, tach w/ light triple pod cause of this. Hope your as lucky as me and just have a bad gauge.

i agree, i've heard of guages crapping on foxes all the time. but given the milky oil, i would have to second the head gasket suggestion.
