1959 To-35

[willy3000]

A friend has a 1959 Ferguson to-35 motor oil has no coolant in it but coolant appears to have some motor oil in it. Coolant is greenish black not milky.
It runs fine no white smoking out the tail pipe and no external leaks.
Is there a coolant additive that has liquid glass in it to seal things up to prevent oil from getting in the coolant?

When coolant gets old it can get a dark glossy look to it. I would have your friend drain and flush the cooling system, refresh with new coolant and see if any oil is actually getting in it.

Thank you very much your response is what I was thinking it could be today. Maybe coolant is just old and need flushing.
I have hear of a coolant additive with liquid glass that might seal head gaskets and cracked block does anyone know of a good product with liquid glass that is safe in these engines ?

Let us know the results. I didn't answer your question about a sealant with liquid glass because I don't know about it. I know there has bee radiator stop leak products on the market for many years.
