2016-2021 Buick Encore 1.4L Gas Engine, AT 58k Miles (VIN B, 8th Digit, opt LUV)

From the listings you provided, the most important point is that the eBay compatibility tables should not be trusted by themselves. For engines, the VIN/engine code and drivetrain are critical.

For example:

• The Volvo T5 B4204T27 listing is specifically an AWD donor engine, while the T6 listing is a different engine family/application.
• The Jaguar 2.0L F-Pace listing is much less certain because the seller explicitly says the buyer must verify fitment by VIN.
• The Mini 2.0L Cooper S and Mini 1.6L N16/N18 engines are completely different generations and should not be treated as interchangeable.
• The Buick Encore/Chevrolet Trax 1.4L engine is specifically identified as VIN B, 8th digit, LUV, which is much more useful for determining compatibility.
• The Acura MDX 3.5L listings are J35-family engines and need to be matched to the exact MDX year/drivetrain and engine configuration.
• The Infiniti QX60/Nissan Pathfinder VQ35DD listing is particularly notable because it identifies the VQ35DD engine and VIN application.

If you tell me the exact vehicle you are trying to replace the engine in (year, make, model, engine, and preferably the VIN), I can go through every listing you’ve sent and tell you which ones actually fit, which are questionable, and which is the best buy.
