Check the hose for small pin hole?

i would check that hose, if you don't know when that hose was replaced last do anyway. mine was leaking there as well, i replaced the hose and no more leaks

Josh, I had the same problem last year on my 87 GT. It was the timing cover gasket. I had to pull the engine to finally get it done. Sorry dude.

------------------

I did my timing cover gasket a few months ago it was not that hard. Took off the passenger side rear tire and did it all from there.

You'll need some special tools to do the timing cover, mainly a harmonic dampener puller and installer. Once you have the pump off it's not much more to get the cover off, some brackets and bolts and don't forget to drain the coolant first. While you're in there you should replace the timing cover crank seal, it's just a few bucks.

Jazz is right, don't forget that seal while you are in there and check your timing chain also. Otherwise not too bad.

Try tightening the hose clamp.

Mine leaked after I replaced It, Run it until it leaks, the shut it off, take off the pulley and see If you can see where it leaks. My hose leaked where it screwed in so I put lock tight on it and its still holding. good luck

did you figure it out, mines leaking in the same place and i fear the same.

thanks...

It ended up being a super small leak in the hose to the heater core hose it had rubbed through on the fuel line bracket. Hope it helps.

I'm not sure what I'm going to do I've nevered drop an engine, might try and rock the cradle to give me more clearance or just have someone do it for me. Maybe it time to start my engine swap.

Yeah that's what happenend for me.... My clutched slipped once and I said that's it time for the swap. No reason to spend that much money and time on something your taking out anyway.
