greenish oil?

[atlnq9]

I just bought this 91 comanche with 4.0L engine and when I changed the oil it had a greenish tint.

I can't imagine what would cause this, coolant doesn't mix with oil...

Does anybody have any thoughts on what would cause this?

Call the PO and ask them if they used Brad Penn oil in it..

I know Valvoline colors their Synthetic Gear Oil green, but I don't think I have seen engine oil be green before. :nuts:

Didn't seem unusually thick, did it? Someone trying to cover up low oil pressure with gear oil?

[atlnq9]

no it wasn't thick and the oil pressure is fine.

 

the valve cover and gasket were replaced just prior to my purchase, could it have been an additive to check for oil leaks? I thought those usually just required a uv light to see the color though?

seafoam. (most likely they cleaned the push rods etc. but didn't think to change the oil)

 

change your oil, call it good

Did the oil have a sweet kind of smell to it ? If so it might be hurricane oil it will not smoke like dino oil it is used in racing applications . Someone my be trying to hide a smoking problem .

We used it in the race car. Weird stuff, kinda looks like alien blood or something.
