Looking for insight into where this fluid leak might be coming from. Appears on both sides of the engine and looks like a thick creamy fluid with a green sheen. Pic below....

Thanks cruiserdan, inside the engine oil cap appears normal and without any clear sign of mixed in radiator fluid, and inside the radiator cap also appears normal.It looks like a mix of oil and coolant. Possible blown head gasket or cracked head?
All of the fluid levels appear just fine.What’s the condition and levels of all your fluids (power steering, brake, trans, etc)?
The coolant is aftermarket green. The slimy stuff is definitely coolant mixed with something else and has a viscous quality, almost like a ointment.What color is your coolant (Toyota Red or aftermarket green)?
What does the slimy stuff smell and feel like? Greasy / oily / viscous?
The dipstick doesn't look like the substance either old or hot, and the engine otherwise runs normally.Pull the dipstick (cold) and does it look like the substance? Does the engine otherwise run normally? Pull the dipstick (hot) and see if the consistency has changed.
What your pictures show looks to be "lung butter", i.e., coolant / oil mix, and it's unlikely to be mixing anywhere other than inside the engine. It's not like there's a mixing chamber somewhere that has gone awry!
ADDED; just went put in the garage to study the area under the hood, and there aren't any coolant hoses that run in that area. My guess would be that under running conditions, you're getting coolant blow-by into the oiling system, and the overpressure is causing the mix to be ejected out of the Oil Dip Stick tube, as that's right where your pictures show the residue, likely blown by the cooling fan and underhood airflow.
The top of the radiator is kinda brownish. 160k miles, 1997.Maybe check your fluid levels and determine which one is low?
Then start tracing that system to find the leaks.
If it's coolant, I'm guessing first, it's a coolant hose or a radiator.
Is the top of your radiator turning kinda brownish?
How many miles?
What year?
Then it's most likely the seal where the top of your radiator meets the aluminum core.The top of the radiator is kinda brownish. 160k miles, 1997.
Will do. Appreciate the advice, given my limited mechanical knowledge. If it is the seal, is the repair replacing the radiator? A local friend is willing to help replace it, if needed.Then it's most likely the seal where the top of your radiator meets the aluminum core.
These are known to fail when they start to turn brown. Mine literally exploded on the highway.
Get this checked and fixed sooner than later.
Wash down the engine bay with some Dawn Power Wash and a hose (try to avoid the distributor and other major electricals) then try to locate the SOURCE of the leaks. it's going to be towrds the front of the truck and may be both oil AND coolant since you're getting a creamy looking crud. it may be two leaks or more leaks of different types.
Replace radiator, flush cooling system.Will do. Appreciate the advice, given my limited mechanical knowledge. If it is the seal, is the repair replacing the radiator? A local friend is willing to help replace it, if needed.
