    What would a rebuilt motor go for?

    I have an M54B25 laying around that I pulled from my brothers car. The head gasket was starting to go between 2 cylinders so it wasn't overheated and there was no oil/coolant mixing. I haven't had much interest from buyers for the motor as it is and I'm tired of tripping over it. What could I get for the motor if I rebuilt it with a new head gasket, head studs, stock pistons and rods, new bearings, rings, gaskets, and valve seals and guides. I'd send it out to the machine shop to have the bores and mating surfaces cleaned up, new valve guides and seals installed and everything checked over. I have no idea what it would go for and want to see if it's worth the time to do it.

    unless your a certified shop and can provide warranty/invoice on the rebuilt motor hardly any more then as it is. Its not worth the parts or time to repair these motors. I just sold a good M54B25 with less then 100k miles on it for $500. There are tons of them out there and not a ton of demand. especially as it becomes less cost effective to repair these cars rather then replace them.

    IMO pull any good bits off it and scrap the block. Things like the valve cover, throttle body, disa valve, coil packs, etc are all worth a bit on their own and have more demand.
