From a dealer. Under the hood everything looks brand new, except the exhaust manifolds. They look original. Motorcraft sparkplug gaps are over spec. The dealer did not advertise vehicle with a new engine, and didn't make mention during the sale. Can you explain what's going on with this Mustang?
Bought a used V6 Mustang
- Thread starter joeO
- Start date
More details, please. Year, mileage, trim level (which engine-if more than one V6 was offered), service history, how'd it test drive....?
You think the engine was replaced? Exhaust manifolds look "original"...how 'bout the top end?
Evidence of work on any fasteners?
Possibility:
Attractive vehicle....some guy trashed the engine....traded it in....a dealership installed a used engine or short block....sold it to you.
Why complicate things by burdening a customer with the whole story? <<joking
How much did you pay? Did you get any warranty?

Somebody washed the engine?
If the sparkplugs are “over spec.” By which, I think you mean that the gap is too large, that implies a long time in service, which would be consistent with the original engine.
Some pictures and details would be helpful, otherwise, you’re not going to get much more than guesses.

Very rarely, if ever, do spark plugs get changed on a UCI at my work. Usually just an oil change, and then air/cabin filter, and then whatever safety items are needed. If something like an engine or trans is needed it gets shipped off to wholesale or auction.
I'm sorry. It's a 2013 Mustang. It was clean under the hood. We look closer after we got it home and everything is actually new.
147,651 miles
Hmm, at that mileage a new engine would a selling feature, but maybe the sales guy didn't even know or forgot. Anyways, I'd have a real careful look at all the fluids, and look at the wiring, lines, for weird bends, damage, and that its all fastened properly not to have a problem eventually from vibration or whatever. Engine swaps have a lot of stuff that needs to be put back in the right order.
Enjoy the new car!

Some people gap their plugs on the high end to theoretically increase spark gap and burn efficiency. I think its not great for the coils though.
Look for a tag somewhere on the engine if you think its new. I believe most engine rebuilders and crate engines are usually tagged, and if so, I wonder if the dealer has the info. Would be nice to know if there is a warranty.

I took pictures but it's not the same. I saw someone clean the white plastic bottles, one was the coolant reservoir in a video. Made them look new, so why not the engine and engine bay? Unbelievable. If I hadn't seen it with my own eyes!
There are some higher dollar cleaners that do an amazing job, but not for cheap. I think “S2000” was one I used for motorcycles, where the small bottle would go farther. It was amazing on a car, but one cleaning under the hood equated to $20.
One nice thing about yours is this … if it had any leaks, it would show. For it to be that clean and stay clean, sounds pretty remarkable to me. Enjoy it!

Thanks. I honestly thought it was all new.
