i got a question on a truck im gona go se again tomorrow its a 93 reg cab with a 8ft fisher plow the guy needs 5 grand for it wich isnt too bad the truck needs a couple of things body work, 2 front springs truck has 70000miles on the cunter
truck has never been bombed
the thing im worried about is the head gasket cause i saw a greenish kinda gew on the side of the engine its just below a leaking injector the one closest to the firewall usualy if i see an engine with gew below the head gasket i start running but on this one im not sure cause that fisher plow pump is right beside the air box and there a hose thats not hooked up and its leaking oil so im not sure if its prestone i see or fuel mixed with pump oil.
is there another way to spot a busted head gasket besides leaking im gona go check for air bubles in the radiator and back up tank tomorow or the day after if i remember correcly if its busted i should not get any hot air in cab and temp guage would get on high temp or am i mistaking any input from you guys is always appreciated im also gona try to find oil in water or water in oil

 

They can leak externally and not put pressure or oil in the coolant. If it looks like it's seeping coolant, it probably is.

 

That's what mine did - it leaked externally only.

 

Same thing happened to mine at 230,000 miles. Right between #5 and 6 cylinder. Mine didn't have any of the sealing trace left on that water passage, it looked like that over the years the weather and heat eroded away the trace.

 

is there anyway to test it to make sure it is coolant like i said fisher pump is leaking and that side of the motor is wet the guy drives it almost everyday i did not notice any white smoke coming out of exaust

 

You could put flourescent dye in the coolant and use a black light to see if it's coolant leaking. If it's a daily driver you will know by the next day.

 

That's what I did and it worked excellent! I used a black light at night, but just the sunlight near sunset made it glow. My driveway glowed real good.

 

how much would that cost me to get a black light and some fluorecent stuff

 

You can get a kit at most auto parts stores, they are about $20 for the light and a few bucks for the bottle of dye.

 

thanks wanna ill check on that tomorrow if you sy 20 its probly around 50 here and ill ask the guy if he wants me to try that too
