I've only seen terrible results from those products

Says the guy with a Northstar that literally left the factory with stop leak in the cooling system 

But I completely agree.  They can work in certain situations, but I would opt to fix the issue properly if it were my vehicle. I always attribute those products to be used mainly in a "we either scrap the vehicle now, or we try it and maybe only scrap it later" situation.

...and it was terrible when GM did it too. FWIW my Northstar has zero stop leak in its cooling system as the problem was fixed correctly, no thanks to the General.

It definitely takes dedication to own a Northstar Caddy AND keep it running reliably for that many years, especially in a salt belt state !  All joking aside, they are nice engines, and can be made fairly reliable if you know their weak spots. 

I know that it's not exactly the same, but the Shortstar we had in our Intrigue years back was arguably more reliable than any 60 degree V6 or even 3800 i've ever owned. It reliably needed the oil level topped off every 1500 miles or so, but outside of a bad CKP sensor and an alternator....that powertrain was rock solid up until the day we scrapped it due to rust.
