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.

I hate to tell you this but it sounds as if you had the timing too far advanced......

How much did the JDM GZ motor cost you?

This GZ in this car I have has over 200,000 miles so I am thinking it will let go any second

On your question I don't know that much about GZE's yet but how old was your O2 sensor

I been doing some searching and reading up and I though I saw 80k miles you should change the O2 sensor

For a stock car no big deal if you don't change but I would think with a pulley the O2 sensor would be even more important

The JDM 4agze cost me $999.09 shipped. Here's the link, maybe the guy will be selling another. http://cgi.ebay.com/ebaymotors/ws/e...d=1,1&item=8030154396&sspagename=STRK:MEWN:IT The O2 sensor was less than a year old and looked fine when I took it out today. Also, I took the motor out today. It took me 9 hours. I've never taken a motor out of a car before and I had very little help doing it. What a pain in the a$$. Anyone interested in an ae92 4agze trans? It comes with a good(ish) clutch and flywheel if ya want it. Seller said it was good and only had 35000 to 45000 miles on it, but I can make no guarentee as I have no way to test it.
