Are you sure it's not just thread sealant that was used on the head bolts/studs? Who did the h/g repair?

In an Auto car tranny fluid can leak into the coolant if there is a hole in the cooling tube. Very rare though.

if it is tranny fluid leaking into the rad-
is there anyway, If thats the case- That i could disconnect the tranny lines into the rad cooler in the rad and run them straight into my external tranny cooler i hooked up? Then it shouldnt leak @ all, and would that really make a huge difference in cooling the fluid down anyhow-eliminataing the in-rad tranny cooler. Oh by the way the rad is a Fluidyne.

please let me know- Thanks Ant

ARP thread sealant.....and he was quite generous with it, and thread lubricant on all bolts as well.

That thread sealant is black..that could be what your are seeing floating around in the coolant. He didn't use any of that Bar's leak to add to coolant did he?

I have this same issue with my new motor, and no matter how much I get out, four passes later there is alittle more oil floating on top. No water in the oil and the car runs great. I just go with it.LOL

well-checked again tonight-

and seen small little ball like oil particles moving around in the rad neck. i pulled the dipstick and oil was clean, Im starting to think its the tranny cooler in the fluidyne rad leaking tranny fluid, not 100% though-Has anyone ever had this problem before???
I mean my H/G are brand new, Ford Racing Graphite H/G's with myabe 500 miles on them, So im highly doubting H/G failure @ this point.

Guys whatta ya think???
Thanks Ant
