There's a GM part number for these tabs (pills) I think. I debugged a 1994 Olds Cutlass (with the 3.1 Liter engine) in the last few months (cheap buy, but didn't make much money on the sale). There were coolant leak issues but not into the oil. Anyway I bought the big TSM for the car off of Ebay and they specify that the stop leak is to be added to the cooling system if you ever drain and flush. Since the P.O. had switched to tap water in the cooling system after a freeze plug started leaking, I did put stop leak in the cooling system after I flushed it and added fresh coolant. I also replaced the upper intake manifold gaskets, but that was really unnecessary I found out. There are specific procedures in the tech manual for gasketing the intake manifold and I think the gasket design has changed since the car was built too.
