Maintenance/Repairs

I have a chevy van with a 5.7L V8. I recently took off the lower cooler line on the radiator on the driver’s side and brown oil/sludge dripped out. I checked the oil dipstick and the oil looked normal/clean. I did some research and apparently this could be due to a bad oil cooler causing oil and coolant to mix, and the oil cooler could be near the oil filter. I drained the coolant and it was normal and the coolant cap didn’t have anything on there. Although I do have an intake gasket leak so I lose some coolant occasionally. The engine oil dipstick and tranny fluid all looked normal. I didn’t see one of those tiny radiator oil coolers near my radiator. Does this mean I might have to replace my radiator? Is there a reason why the oil in those lines is different than the dipstick? The oil and filter were changed about 2000 miles ago. Does anyone have experience with replacing this oil cooler or have the part number?
