I was changing my valve covers on my 89 and notice my oil on my heads looks green. Not sure if antifreeze is mixing in my oil. I looked in radiator. The coolant looks a normal green color with no bubbles while running. I took a sample of my oil and sent it to Blackstone laboratory for a analysis. I am still waiting for the results. I am just curious what other people think. Thanks.
There is some high end European motor oil that is green in color - but assuming that you aren't using that - you have a major problem...
If that much coolant is in your engine - your radiator must be darn near empty. Time to do a cooling system pressure test and a cylinder leakdown test. That will pretty much tell you what is going on...
That's what I thought but wouldn't the engine rattle with antifreeze for lubrication?? I'm following to learn the answer,
Pull the oil drain plug and see if coolant comes out. I blew out an intake manifold gasket once which dumped coolant into the oil. The Engine did not rattle even with several quarts of coolant in the oil. The oil pressure gauge was bouncing around so I shut it down quickly with no damage to the engine.

Please keep us posted - that looks too weird, as water in the oil would be kinda yellow, and those head's top end look beautifully clean.
Never seen Pure Ethylene Glycol antifreeze mix with oil.
Did you put the oil in this car? Could it be some odd green oil?
The engine sounds normal but once I the engine warms up I have low oil pressure at only 7 psi at idle. I am not starting it any more until I solve this. Thank everyone one for the input. I will post an update once I find out the problem.
Usually, coolant mixes with the oil and the color is creamy-white to creamy tan. Not fluorescent green.
Did you recently purchase this car? Is the oil in it now the oil that was in it when you purchased it? If yes and yes, I'm thinking that is UV dye added by someone to assist in locating and identifying an oil leak for the previous owner.
Blackstone will have the answer. Really good move to let them create a report. Don't drive it until you know what is going on. I'd change the oil regardless, but not until you know that it is not "coolant", or you waste the oil change.
It might be oil dye. I thought my car was leaking oil but could not find the leak. I put oil dye in it and still did not find the leak. It just stop leaking. This was about 4 months ago And only driven it about 100 miles since then. I will wait on my report. Thanks.

I have to go with that being oil dye, I have never seen coolant mixing with oil look like that. Dumb question, what does the liquid feel/smell like ? Antifreeze has a very unique smell and texture. I would also check your oil pressure with a separate mechanical gauge, 7psi is low.

I did think about smelling it. My valve covers are closed now. But I would agree. I don't know why I forgot I put dyed in until it was brought up
