Took car to shop and had compression/leakdown test. All cylinders near 160 but #4, which is at 125 and had 24% leakdown(crankcase), where all others were less than 20%. He thinks I should just drive it for the summer and inspect it in fall/winter as I probably can't hurt it more. Is this the case? Is it probably a cracked ring? One way to find out, right?
