I heard it run, saw the car it came from, and where the damage was on the donor, I got pictures of the odometer, I ran the carfax on the donor car, and searched the 'net until I found enough to make me feel good about it.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

12 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

as I look for options to get my roller running again, I see there are several complete engines for sale. One 3.4 in particular has about 20k miles and said to run excellently, but has no documentation other than external pics. Price is what I consider to be top of the range. Seller is an eBay regular out of CA and has good feedback and many parts for sale, but offers no history of the part other than �runs excellent�. I know eBay and these engines can be a roll of the dice, but looking for others experience with buying used engines.

POST 2Original post

The only seller I personally have purchased several engines from is QualityPorscheParts out of New Mexico. Never a bad deal from him.

POST 3Original post

Probably depends on price, at the right price you could justify the risk

POST 4Original post

I think it's fine to purchase off eBay, but make sure that you get enough information to feel good about it. No real way to verify claims of low mileage unless you can see the donor vehicle. If you can get the donor VIN, you can run a carfax to see if the mileage is in the range of reasonable. I bought an engine from QualityPorscheParts off eBay last year, but before I did, I researched the hell out of it. I heard it run, saw the car it came from, and where the damage was on the donor, I got pictures of the odometer, I ran the carfax on the donor car, and searched the 'net until I found enough to make me feel good about it. Even then, I made sure to replace everything I could think of while it was out of the car before installing (AOS, RMS, plug tubes, plugs, orings, seals, belt, thermostat/housing, waterpump, etc.). PS. It is for sale here on Rennlist, either the engine alone, the entire car intact, or almost any combination in between.

POST 5Original post

Year/make/model of your car? M96/01/02/03 replacement engine? What's the ebay engine number? What DME version do you have and what DME version for the ebay engine? And to answer your question....no, not sight unseen and not without hearing it run.

POST 6 / ORIGINAL POSTEROriginal post

I did get the VIN, mileage is correct, it was a one owner car that appears to have been dealer serviced. the bad news: it is a flood car out of Florida.

POST 7Original post

I bought a used 3.4l from Quality as well and have had excellent luck so far with it.

POST 9Original post

A flood car? No way would I buy that. Not unless you are planning on taking it apart and rebuilding.

POST 10Original post

Quotes source post: 14823994

If I lived near North Carolina I would monitor DC Automotive for what you are looking for & go checkout the engine before buying anything.

POST 11Original post

Just bought my first parts from DC auto and was impressed with the buying experience.
