So, I blew my engine a few months back but haven't had time to pull it out. Here's the situation that it blew:

I had just replaced some solenoids and vacuum hoses troubleshooting a primary boost leak. After putting everything back together, I took it for an easy drive. I was in 2nd gear at 3000rpm, shifted into 3rd... and that was the end of her.

Now, I'm about to pull the engine and I found something wrong. Inside the black rubber hose that connects to the secondary turbo (if i'm right, the one towards the front), I found a rag. It was twisted tight, and formed to the shape of the turbine. Do you think this would cause the engine to blow?

What tests have you done to confirm that that engine is indeed blown?
What mods do you have?
The front turbo is the primary. The rag would have reduced/stopped airflow, causing her to run rich. I wouldn't have thought it would blow the motor, though.

Tried starting it with the rag removed?

I've ran compression tests showing almost 0psi and I used a borescope inside the plug holes which showed missing/cracked apex seals.

The car is stock minus the Koyo radiator.

The car would not start since their was almost zero compression.

Yesterday I got the engine out and looking inside the exhaust there were shredded pieces of that rag. I hope this is the reason the engine blew. I'd rather it be my stupidity than something else i need to troubleshoot!

wow... a rag. the biggest thing we say in aircraft maintenance : tool accountability. you do NOT want a lost tool to be found by the pilot or worse, the airplane. account for your stuff before the job and account for your stuff after the job. everything....

Absolutely. Always accomplish tool accountability after every job. That way you don't find out you have a missing apex after you've been to 4 different jets it's always good to take your time and be organized. If you're not organized that's how you lose things or things like this happen.

Wow. That sucks...
I guess thats a good lesson though. Work slow and methodical. Double check your work. And after everything is put back together, stand back and look at the job for a second. No missing tools? No spare miscellaneous parts?

And as I found out once, before you start it up, take all your tools out of the engine bay and set them away from the car. Otherwise vibrations cause them to shift and fall into places that can cause damage...

I'll leave this here so everyone can see what a funny guy you are.

This stuff belongs in the lounge, not in the tech section. Please stop this kind of stuff immediately, I hate having my time wasted and you won't like the result

thanks

seals?

yes, even a rag can scrap an engine. bound up seals have to go somewhere. in fact i would say it's more likely a rag to scrap an engine than a piece of metal because the rag will catch and roll under the seal. BUT it is surprising it made it past the intercooler.

live and learn, it can happen to anyone.

So, it seems like I didn't blow the engine. The rag was shredded into tiny dust particles which ended up securing all the seals stuck!

I'm still going to rebuild it since it's out and open as well as replace the clutch. I'm thinking a stock clutch will do.

I also need a new/used radiator fan so if you know where to get one or have one for sale let me know, thanks!
