I just finished rebuilding my integra's LS engine, and before it was running really badly, and after 4 days or so, i did a "first start-up". Well, it cranked and turned over just fine, only theres a HUGE problem; the motor is making a slight knock knock knock sound, and there is white/blue smoke pouring from the bottom/side of the block kindof in the area where the oil pan meets the block. The smoke doesnt smell like anything i've smelled before, not like oil OR coolant. I'm not really sure what should be done next, or what seems to be broken.
Someone please enlighten me as to what that could be!!![]()
