Things JUNK! The so-called head bolt update was less head bolt tq. They still blow head gaskets because the threads pull out the block. Have to drop the engine and transmission out the bottom as it can't be fixed in the car.
The ac blower also requires that the engine be dropped to replace it.
The engine requires stop leak in the coolant to keep the coolant out of the oil pan. It seeps past the cylinder liners and the block.

The Northstar also requires stop leak. Sticker right on the core support.You're thinking of the 4100/4500/4900 engines with wet liners, Northstar's have cast-in cylinder liners.
A '06 DTS has the blower motor inside the cabin.
That was my thought also. The pull a parts are full of them, not from collision or neglect, but a failed Northstar.Many of the pull a part DTSs are the best looking vehicles in the yard. I would love a DTS, just not willing the risk associated with the Northstar. I also love the 2004/2005 Pontiac Bonneville GXP with the Northstar. About zero of the GXPs made it past 100k miles without the Northstar failing.The bone yards have a sea of them to choose from. You have that going for you.
The joys of having the starter located under the intake manifold....
