I built a tough 192 for my LX Torana a couple of years ago, my first serious attempt at a mechanical sort of project. Broken up by interstate trips, uni etc, it took about 2 years by the time I finished everything and went to drop it in. The big day arrived, I had the car and engine in Dad's shed, and after much stuffing around with the engine crane the spline finally lined up and dropped in.
Bursting with anticipation I bolted everything together, turned the engine over on the starter to get oil pressure up, and started it. Joy! It ran! The rough idle in the tin shed was music to my hoonish young ears! The thin, steady trickle of running in oil onto the shed floor from the back of the engine was less inspiring however.
Much prodding, poking and chin scratching led my father to the inevitable conclusion that we were going to have to pull the f*ckin thing back out again. Which we did. All gaskets were clean, all bolts tight. Everything looked great, till I suddenly realised I was reading the numbers on the back of the lovely lumpy cam. I thought the guys making the welsh plug kits were just being generous & that's why I had a spare.....
