Motor ran without oil. Toss it or rebuild?

[truegearhead]

Last season I lost an accusump line and ran the car completely out of oil because I’m an idiot. I’ve since swapped it out with a 2.7 but still have the old motor sitting around. It still runs but even with new oil in it you can hear the bearings. Are these worth rebuilding? Can I do anything creative like install a 3.6l crank? It’s an early 2.5

Cheers,
Stu

Definitely no 3.6L cranks, I have a set of NOS Porsche rod bearings for sale if you need them.

I'm just gonna toss my old 2.5 block (IMS failure) at the local European shop. If they give me like $500 I'll take it. If not it becomes a coffee table.

That's my plan, but you might split yours open and find the bores clean and nothing warped or too badly mangled.

Well my friend, you are not alone... Nothing to do with the Accusump, just human error in this case.
When I get another engine back into the car, maybe I'll tear the block down and see what kind of damage complete oil starvation does to an M96 engine I guess my question would be if the camshaft/head cover journals are damaged or still usable. There was certainly a heavy rod knock and low oil pressure light.

If you have the space and the time, you might consider tearing it down. You can see whether it can be easily salvaged assuming, of course, that you can do it yourself. If it were a 3.2 it would be worth putting some effort and money into it but I wouldn’t imagine that there’s a lot of call for a 2.5. I’ve done a couple of teardowns which you can see on my YouTube channel: https://www.youtube.com/user/12shoes2

Usually the rod bearings are the 1st to go followed by the crankshaft rod surfaces soon after. Good crankshafts are getting hard to find & expensive.
