Default Is it possible to "unseize" an engine?

Story: My mate has a golf tdi he hit a speed bump and it knocked the front end.

Carried on driving there was a split in the sump and it emptied oil.

Now the engine is seized, will it need a new engine or can it be rebuilt??

New engine/rebuild, roughly the same thing really. New pistons/rings will be needed, along with a rebore IMO, along with all the other parts involved in pulling an engine apart this far.

Ive seen them seize up and when turned over with a breaker bar they have ran again for a while, not often though and its only the sort of thing you do before selling it on if you are a rogue trader, it blatantly wouldnt last.

Fit a secondhand engine is best bet

my mate does coke down the bores,he buys flooded cars from local salvage companys like copart,furburs or car salvage supermarket and finds even when unsiezed if they knock its a easy fix.
worst case is a new donkey but he always does well breaking the engines if the bottom ends proper fooked like selling the head etc.

If they knock, its normally the big ends, if you just whip the sump off and replace them then they shut up, and last all of a couple of hundred miles typically due to the crank being scored.

So although it allows you to flog them on and rip someone off easily, its not really ideal for your own car

Only way to do properly is crank out and replace or regrind, and thats into the realms of no longer being an "easy fix"

Having bought a seized/salvage car before(mondeo) that was ran without water and oil, the shells were utterly destroyed, I had to chisel no 3 big end bearings shells from the crank, but could not move the two stuck pistons no how, needed a big press to get those out.
I'd just get a s'h lump for it, but make sure it's got oil in it!!

Before you do that pour some sand down the intake to "port" the head then use some salt for the "polish"

lol i never mentioned he auctions them,he doesn't care if the pope bought one so long as the cheque clears if the cranks look fooked he just gets a second hand donkey in.

i have seen the odd one where he has kept it to smoke around and only put a rod/piston in and its held out ok.
i do know people who put very heavy oil in engines to stop them knocking,sawdust in them too and then auction them off
