i have a 1992 ford f150- 5.0l engine. i have a small leak on the back of engine where the transmission and engine meet. what do i do? it is a very small leak but i am worried about it please help if any one has any ideas.

 

WTF is leaking, and where from? Leaks usually show up underneath where they start.

 

Rear main seal?

 

guys the title says "Radiator fluid leak"

i'm gonna take a guess and say an externally leaking head gasket/cracked head.

whats the mileage? has the coolant ever been serviced? has it overheated?

 

the mileage is 167,000 and yes the coolant has been serviced

 

Do you know where it's coming from? Heater core lines maybe? I can't see it from here

 

you got new smiley's to play with

 

If it not coming from the heater core its a freeze plug. Transmission removale would be required to fix that and its not a leak that should be ignored. Had a freeze plug fail on a POS Dodge I had and it caused an engine melt down. I would think it the Heater/hose/core leaking because I've never heard of the freeze plugs developing leaks in a newer ford. Guess it could be a headgasket to.

 

how hard is it to change the head gaskets

 

its not bad on a 5.0. you gotta pull the upper and lower intak,e and valve covers, and exhaust manifolds, the a/c compressor, the air tube that runs from pass side head to the driver side head, etc. and have the heads checked. its a pretty self explanatory job on these engines. your better off getting a chiltons or haynes repair manual for it though. it goes through it step by step.

but first find out what the problem is.
