I'm going the look at a used car (2005 MPV van) today with a replaced engine. I don't think that I've ever looked at a car with a replaced engine. Besides the obvious, what should I look out for?

I would want proof that the engine swap was done by a reputable shop. If the seller told me he did it himself in his garage, I would pass.

I would be concerned with who did the work. It's easy to mess things up when doing something like and engine swap; mess up a plug connector, break or crimp a wire, break a sensor, etc.

Just make sure the engine runs right, make sure the CEL lights up upon start and turns off, and make sure there are no leaks around the engine and between engine and transmission. Also check the oil cap for sludge buildup. If the cap has sludge - the rest of the engine does too, and usually a lot worse than the cap.


I've replaced a few engines in my friend's shop (he has a lift, duh) and every time the engine had less miles than the car. For example - last car was Lexus IS300 with 134k that I put an engine in with 100k miles. Did I have the paperwork to prove anything? No. Did I tell the new owner about the "new" engine when I sold the car at 170k miles? No. The car is still driving out there. Last time I checked - it was at 220k.

Was it replaced with a new/rebuilt engine or a junkyard engine with unknown history?

I did a motor swap on the Ford Transit, mated it to a totally rebuilt tranny with papers now in the glove box. Original engine had 180k. The donor was a engine with under 40k. 6 months no issues but was a Ford trained mechanic that I assisted for better or worse.
Basically look at the paper trail if the work was done by reputable shop and replacement was checked out.
Saved me big $$$ and have a very nice drivable vehicle that with proper care will last easily another 180k without issues.

It could be a plus is a reman engine or a negative if a junkyard engine that the PO did himself.

Some vehicles like my 2001 Jeep GC 4.0 are likely to need an engine by 100,000 miles due to piston skirt cracking.

Find out if it has a remanufactured, rebuilt, crate, or used engine. If it has a reman with paperwork, I would definitely consider it. I bought my Oldsmobile with a low mileage Jasper reman, and it has been a good engine so far.

Newly rebuilt - $2000-$3000. Used from a junkyard, that is sparkling clean under valve cover - $600. I think the choice is obvious here. Plus the junkyard engines comes with all the sensors and most of accessories & wiring- which means less labor in swapping that over from the old engine.

I had a Jasper engine put in my 1995 Escort in 2001. I'm still driving the car too. In this particular case it's a big plus since the Jasper won't drop a valve seat.

A replaced engine adds no value to a vehicle despite what the poor sap who paid for it thinks. So make sure you pay for mileage on odometer not that 30k engine.

2005 is good because if sensor or item not correctly installed the Check engine is on. Make sure it illuminates when in on position but motor not running.

My Subaru had major engine work due to valve burning requiring engine removal. Not a single issue but mechanic is Subie expert. He said it started first attempt no lights after the install.

If the car runs right and there's no check engine light, what is there to worry about? What could you mess up during an engine swap that would not cause a no-start, a driveability issue, or a CEL?

The answer is obvious - if I was to swap an engine for myself.

Buying a car with a swapped engine I would prefer the one with paperwork and a warranty over the one some guy swapped in his garage. I trust my own work not other people's work.

Re-using old parts that should be changed like gaskets or belts.

I(myself and Dad) put a Jasper 6 cyl engine in a 66 Chevy in 1972. It performed very well.
