Broken rod bearing
 

So my Supra took a turn for the worse tonight, it had been diagnosed with needing a new engine since about two weeks ago when I took it into the shop only that much to my surprise, my newly purchased 89 supra had thrown a rod bearing in the 6th cylinder, and was a staggering 4 quarts low on oil! I felt like such an idiot because I had checked the dipstick a minimum of 5 times before it started happening... Does anyone know a reputable site on the internet to purchase a JDM 7MGTE? Any information would be much appreciated.
