Hey guys im new to Thirdgen.org and i just recently (in the past 2 weeks) bought my first third gen, a 92 RS, well i was out giving it an oil change when i did some exploring under the car and noticed that the botom of the block was blue and that there was a piece of metal attached to it so me and my friend pulled it off and it read "Advance Automotive Industries Inc"
with a part number of 4079 and a serial number of 24346-A-22
i looked on the web and couldnt find anything about this place so if anyone could tell me what it means or give me info about the company that would be great cause i dontknow if i have a rebuilt block or not?

 

be a very sure bet to think you have a replacement engine in your car
