Can the oil cooler on a 1996 350 vortec leak anti-freeze into the engine oil?

Yes it can but the thing you have to look at is the oil pressure is higher the the coolant pressure. Your oil is about 30 to 60 psi, where as your coolant is about 16 psi, at running temp. I would look around the intake manifold in the corners of the heads to see if any coolant is leaking out or showing signs of wetting.
Now the coolant can enter if the engine is off, the pressure in the coolant would seep in, put you can look under the rad cap to see of a caramel color sludge is under it. Then I would suspect the oil cooler. I have had to replace the intake gasket on a 91 Chevy seen the coolant leaking from the cross over of the heads to the water neck housing. Aluminum has a tendency to corrode at these areas of water cross over. If this is the problem, just add a little silicone to the adjoining areas of the intake and the gasket to the head and it will hold.
Good luck.
Forgot to add the you will have to remove the manifold to fix the leak if it is that area.

Why would you have antifreeze in the oil of your 1996 Chevy Suburban engine?
That is a very common problem with the Vortec engines. You must REPLACE the Intake gasket and then change the oil and filter a few times in a roll after letting the engine run a few minutes each time until you get the engine oil to clean up.

By running the vins and serial numbers on the VORTEC engine its self and going to the DMV you might have to pay them $50 but it will give you basically all the information on it! (:
Can a 350 from a 1988 gmc truck replace a 1996 Tahoe 350?
The 88 engine is a TBI / Throttle Body injection engine. I don't know the month of 1996 when they changed to the vortec engine fuel system, But I believe it was in late 1996. You should know if the 1996 engine is a TBI engine or a vortec engine if you have Sean it. So if it is a TBI engine then you have no problems, Put it in there and hook everything up and your good to go. Now if it's a vortec engine you have problems, None of the wireing will hook up to the 88 engine sensors. And the 96 computer will not run the 88 engine. And the fuel pump in the 96 Tahoe has to much fuel pressure for a TBI engine. You can not put the vortec fuel system/ intake manifold on the 88 engine because none of the intake bolts will match the heads or vise verse. You will be opening a can of worms. You need to go back with a vortec engine if that is whats in the Tahoe now.
