I put in a D16Z6 in my old 93 civic out of a wrecked car that i bought for $100. Everything looked fine, except for the dented oil pan. After the swap was done, i was so tired of messing with the car that i didnt bother replacing the oil pan and I was ready to test out the new VTEC motor! Well everything ran "fine" and continued driving the car for about 2 weeks worry free-meanwhile noticing that VTEC just didnt feel right. On my way to class, i was getting harassed by an SUV and decided to take off and get away from the maniacal soccer-mom.. I ran through third in high RPMs and i guess I didnt get enought oil or oil pressure or whatever and slung a rod completely through the block! funny part is-I was planning to swap out the dented oil pan for a good one and give the engine an oil change and tune up after i got out of class that day.
