[QUOTE="absidian, post: 227960, member: 4356"] Basically when a crack occurs in the block then water will seep where it shouldn't. In most typical cases it will seep into your oilways and mix with oil, and vice versa, resulting in major failure eventually. With cracks, I would be concerned with engine longevity rather than loss in performance because it is only a matter of time before failure. Best to get it tested... you never know, fingers crossed maybe it never cracked/warped at all. After fixing the leak, keep an eye on the radiator water's quality (look for oily gunk), check regularly for "mayo" under the oilcap and monitor your exhaust's output (excess steam, coloured smoke).
