The thing I didn't check

Guaranteed when you read this you are going to be yelling at the screen...

In my defense, the day the turbo blow up, I started the engine up after figuring out the turbo had blown, I might have mentioned this in an older post... the engine stared up and idled silky smooth and was quiet as it did before the turbo blowing up, there was a lot of smoke since the turbo had coated the inside of the exhaust, but other than that there was no indication that anything was wrong with the engine... coupled with me scoping the exhaust ports and seeing no marks or damage of any kind... So I finished the assembly, got everything buttoned up and pulled the plugs and injector connectors and cranked the engine until I had oil pressure, bled the coolant system and then got ready to fire the engine up for the first time in months... well here is where things didn't go so well. Upon starting the engine up, the was a ticking noise coming from the engine, loud enough to not be lifter or injector. I called a mechanic friend of mine and sent him a video... long story short I pulled the engine to start stripping it because this sounded like a piston problem.

The engine out process:





The carnage:



I dropped the engine and the head off at ARE on the Monday to see if they would be able to save it, which they said they can do.

I could kick my own a$$ for not checking the engine internally over winter, because if I did, I would have had a car to drive this season... rookie mistake
