Overheating: worst case? engine replacement?
Hi guys, fairly new over here on the water-cooled side.
What does it mean when a 944 is no longer running due to overheating? Is it likely seized? Does seized mean the block is trashed or can it be rebuilt? If my planned mileage would be low (3rd car) would swapping in a used engine be a more economical alternative? I wonder if a seized engine would count as a rebuildable core?
What are some ballpark costs of available options? TIA.

Well.... one of the things that it means to me, is that there's no way to check for certain problems in other areas... e.g., tranny. Which means the "cheap" porsche could become expensive, quickly

one thing i learned from my project. if you're going to buy a non running porsche, make sure you pay lower than bottom dollar for it. cause the repair bills will stack up fast.

Could mean lots of things. I picked one up this way that had lost a HG and overheated. Turned out to be a good deal since it only need a HG replacement and head trued. Rebuilding can be expensive (2-3K and more). A used block would be your best bet if it needs replaced (500-1K). If the motor in it is siezed, it's not worth much at all.

define "no longer running due to overheating" please
does it run but overheat/cause the coolant to overflow quickly thus making it basically inoperable or does it not run becuase the engine caught fire and key parts "overheated"?
If the engine still turns over and has good compression/leak down, odds are the problem is either related to the coolant (probably needs to be drained, check for leaks or flow problems), the fans (check that they turn on/off) or the radiator (does it leak? are the fins smashed?)
Otherwise, you might be looking at buying a new engine ($400-4k depending on model and what condition engine you're willing to live with) plus swap ($0-a lot depending on if you do it yourself or have it done professionally)
