Had this in my temp issue post, but thought a new thread would be good since it's a different topic.
The short version - got a deal on an '06 DTS. Discovered overheating & confirmed combustion gasses in the coolant. Subsequently found a used engine, with less miles & warranty, & decided to do a swap. Eventually, I will get to tearing down the original engine to determine if the problem was just a failing head gasket, or if there's a crack or warping causing the issue.
So my questions: While I have the replacement engine on a stand before doing the swap, what seals, gaskets etc are the weak links that should be replaced?
Already planning to replace brake lines, faulty power steering hose, oil pan & probably valve cover gaskets, plug tube seals etc. Were crank case gaskets a common issue, or oil pan bed plate seals?
