So I started hearing this knocking sound a month and a half ago. I took off the oil pan and there were all these metal shavings under the #1 rod. Bad news. So I polished the crankshaft with sandpaper for 3+ hours and put in new bearings. I knew this was just a bandaid but I didn't have money to fix it properly. It lasted until two weeks ago when the knocking sound returned and transformed into a crashing sound accompanied with random pings which sounded like stuff hitting the oil pan (bad?). So anyway, I knew it was toast, but I got it home. And also, oil was being forced out of the valve covers, and when I checked the oil, large amounts of smoke poured out of the cap hole/ dipstick hole. My dad, who has been a mechanic for 38 years, says it also sounded like it burned a piston. I have a 180mm NST crank pulley on it, and I know that a larger crank pulley creates a lean spot below 3500 rpm. Do you guys think that that could have been a contributing factor to why the piston burned. I know it probably didn't cause the rod bearing to fail though. If that is why it burned, now we have a really good reason to get a gruntbox, besides performance. And don't worry, the '2 isn't dead for good. A JDM ae92 4agze motor is now sitting in my garage waiting for me to put it in.
