Today I put techtonics tuning's aluminum exhaust on my car (complete turbo-back). After it was all done I started the car and it sounded great. After it was running for a little it started making a harsh squeal and my buddy said I probably got some coolant on the belt and to rev it. I revved it a little and the noise got much louder for a split second then stopped. Long story short the noise kept randomly appearing at idle and I thought something was wrong. Then, when I went to drive it after putting it into gear it started making the noise again and once I started actually driving it got louder as rpms went up. The noise also kinda spooled the way the turbo would. I read a few posts on here that said a loose EGR cooler connection may make that noise as air escapes (and I removed that to get the cat out so it made sense), so I decided to just head home and check it out when I got there. A few roads down I went to go up a hill and I lost the squeal completely and a lot of power. No turbo noise or anything just loud diesel engine sound and a huge lack of power. I am 90% certain this is a blown turbo, but posting here to see if anyone has anything to input or any suggestions on how to be 100% sure.
