Engine replacement = warning sign?

Hello,

Keen to get some opinions / views on cars that aren’t running their original engine. I’m only talking about ones that have had a like-for-like replacement due to engine failure, not engine upgrades. Should one avoid cars with a replacement engine? Or is it to be expected to see cars on their 2nd / 3rd engine when they get to 40 years of age?

Thanks

Mine isn't running the original engine - failed shell caused damage to the block. So I got another block, and  rebuilt it - re-bored, new pistons rings, shells, re ground crank, balanced etc. Loads better than the original was (even before it threw a shell).
I personally see nothing wrong with it provided it has been done properly and not a bodge job just to sell the car. If it was done and the owner has put some miles on it, then I'd say fine.

Second one maybe, third or fourth, is a sign that the PO didn't do squat to the car.

I guess it depends on which model of Golf it is and how original it is, if it's never been painted or taken apart and has matching number engine from new then it will be a rare car indeed but most have been painted at some point especially if it's a tin top car as they rust away and if it's had a replacement engine then that's fine as well.

I think changing the engine for something else like a 20v turbo or VR6 then you can lose money….

Most VW water cooled engine will cover 200,000 miles plus if looked after and some have even reached 500,000 miles and still going.
They used to say that  at 100,000 miles then engine has just run in..  

Interesting responses, thanks. Always been curious if there exists such a thing as a 'bad' car. Basically one, where all the parts coming off and onto the engine are functioning in a way that is counterproductive to the longevity of an engine block. Personally, I don't see an engine replacement as a problem but I guess it helps if you have the story to go with it…

Mine doesn't have original engine, a long story, rebuilt cylinder head,  the wrong mechanic and a load of naivety resulted in big end failure.

That was probably 12 years ago, the car has a dx out of an 88' cabriolet which I paid £100 for and the 82' dx has sat ever since. I do intend to at least take the original apart and inspect one day, maybe even rebuild it if it's not too far gone.

As you say, they're 40 years old now.
They've gone from must haves to £500 snotters and are back up there now, so it's not unreasonable to expect at some point in it's life, it was in the hands of a biff.
The VAG shared many things, so as long as the replacement engine is in good nick, what's the problem?

I'm on my third lump
Original, with original 'box (still have in the shed) 1.6 eg - tuned it to its limit.  Suffered a partial seizure, rebuilt, diff started to fail.

1.9 TSR lump, with a short ratio gearbox, the worst combo going, (great box,  great engine,  just not together)

Now running a KR lump and box with a diesel 5th gear mod.  Sadly due to life, not had a chance to play for a few years.

I'll make next year's AGM!
