F150 has had what I deem excess pressure in the coolant overflow. Until recently, I haven't seen any coolant leaks but have noticed that the coolant smells funny. Almost like gas or exhaust.
Last week there was coolant leaking out from the back end of the motor. Then one has the truck wouldn't roll over. Hydrolock, I believe it's called. The day after, the truck started and there was coolant in the oil.
My assumption is that one of the head gaskets is blown. I don't want to tear into the motor until I get a few opinions. I did get a code P0303 which is a cylinder #3 misfire. By the way, the truck has 170,000 miles on it.

Any help?

 

the oil is milky white?? she has 170k in here??leaking coolant at the back? sounds like new headgasket time. or maybye whole new motor.

 

headgasket has to be leaking...

 

Doesn't necessarily look milky, just discolored. Light brown in color.

 

Headgasket is what I was thinking too.

 

yup head gaskets,that sucks

Oh and don't be running it like that either.

 

if I were you... Id swap in a new engine...
