January 21, 2005: The source of the oil use has been found.
The forged pistons protrude slightly from the block. When cold, they were able to rock in the bore slightly and they'd hit the head. Once warm, they were probably okay as the engine never made any alarming noises. Regardless, this behaviour meant the oil rings were damaged. Oh well, I did get a great deal on the engine so this isn't a major problem. I'll check to make sure the pistons are okay. If not, the engine will get bored out to 80mm and I'll put in some fresh ones. It won't be the cheapest solution but it'll give me a bit of a power bump. If the pistons are good, I'll pop them back in after being slightly cut down to prevent this from happening again. Hopefully I'll have this all back together and in the car in a couple of weeks. I have access to everything but a good set of "street" 79 mm rings at the moment.
