Radiator Goo

I'm starting to fix up an old 73 chevy to do a little mudrunning and i noticed when checking the radiator out, it has a thin oil goo coating on the inside of the radiator and hoses. is this a sign this thing ran hot and cracked the block and oil leaking in? the only time i have ever seen this before the oil in the rad will be white and foamy, but this is grey and real thick and not foamy. i also noticed this truck doesn't have a t-stat in it making me think the coolant isn't getting hot enough to liquify and mix the oil. any thoughts?

Re: Radiator Goo

umm, this is a guess outta left field, but could it be the silicon from the antifreeze that the truck used? you know, the coats just added up. and if the trucks been sitting, then maybe the goo is just...i don't know, transforming/growing/aging/curing maybe???? did i just sound real dumb there???

Re: Radiator Goo

it almost sounds like your describing some pellets used for radiator sealing. i forgot the name of it and don't know if they still sell it. might also be lubricant for your water pump.

Re: Radiator Goo

i believe we've figured it out around here. we believe it's water pump lubricant put in there from the original owner. i called the fella i bought the truck from, he said it was there when he bought it. he said he thought the same as i did for a awhile (cracked block) but there was no decrease in oil or white foamy stuff ever. since the post this morning i put purple power in the rad to clean it, lo-and-behold after about 15 minutes of running, the pump started squeaking. so we looked at each other and the light bulb clicked, LUBRICANT ! so i do believe this is good stuff and not bad now. thanks everybody for the replies on and off the board! mick

Re: Radiator Goo

Yeah, they still sell it. Thats what my grandpa used for years in his trucks. Got a leak, just throw some pellets in there and your set. The stuff he used was barnes leak or barrs leak or something.
