1994 Corolla Engine Serial Numbers

[BlownHeadGasket]

Hello! I am still working out some bugs from a used 1994 Corolla Wagon that I picked up last year.

Previous owner had a new engine and transmission installed. I have been trying to figure out which engine was put in. Standard on the wagon was the 1.8L engine. I think that we have the 1.6L 4AFE.

The serial number on the engine block is 4A-K085409. Any ideas on what this means (other than it is in the 4A Family)? I have a hunch it maybe came from Japan (based on a timing belt replacement sticker with japanese characters and the mileage data in KM).

It would be awesome if some one new how to decode the serial number.

Thanks all.

085409 would be the serial number
K I think is the plant, not sure. serial number format has changed slightly post 2000 year.
4A is the engine family as you said, post a photo of the engine
