Hello, Fellow Subaru owners. I have a 1993 Impreza LS. The VIN code says that the car has a 1.8 L as does the sticker under the hood, but in actuality, the car has a 2.2L The car was owned by my wifes grandmother before we aquired it and the engine was never changed to anyones knowledge. Could this have been some sort of "special edition" or could a fast one have been pulled at some time. I highly doubt the latter, but you never know. I am also in the process of changing timing belt and all oil seals under timing cover. What is the best way to get the camshaft seals out? Thanks in advance for all you input and help.
