That's actually considered a short block. A long block has new heads. No engines are sold with any accessory components.

From Wikipedia:
Long block is an automotive term describing an engine sub-assembly consisting of the following:

* Short block. The long block is always a superset of the corresponding short block.
* Cylinder head. A complete new or remanufactured cylinder head assembly is installed with a new head gasket and torqued to specification. Complete cylinder heads include new or reconditioned valves, valve springs, valve guides (if applicable), valve seats (if applicable), valve locks, and valve keepers. The bare head is free from cracks, warps, or holes.
* If the engine is a flathead, then the valve train is installed if the short block did not already have it.

On most engines, the camshaft will be installed. On many engines with timing gears, the camshaft will be timed. A Long block engine replacement will typically require swapping out parts from the original engine to the long block. These parts include the intake manifold, the exhaust manifold, Alternator, Power steering pump, if any, and Air conditioner compressor, if any are installed in the vehicle.

Short block is an automotive term describing an engine sub-assembly.

A short block is the portion of the engine block below the head gasket but above the oil pan. An in-block cam engine will also include the camshaft and timing gear. The overhead cam style of engine will not include the aforementioned parts on the shortblock. A shortblock is usually purchased to upgrade the water jacket, piston size or bore. Assemblies typically include the crankshaft installed and balanced along with the main bearing.

 

I know the difference between a long block and a short block.

Nissan said the long block was replaced, and I have all of the documentation that says the same thing. If it's a typo, so be it. Although I don't think a mistake like that would be repeated as many times as it has. If it's wrong, ok then, it's wrong. But frankly, for me anyway, definitions are pretty trivial. All I care about is getting the Z fixed.

 

Mine was replaced with a new short block for my consumption problems.

As far as a lemon law buyback... no. You have to buy the car new to qualify.

 

Yeah as far as I know the TSB ok's the replacement of the shortblock.

OP I'm likening your situation to buying a car with a salvage title. Something really bad happened (accident/flood/fire/etc) and the contract you signed to buy the car likely contained something to the effect of "as is".

Point blank, you made a bad choice buying that car.
