Did I blow a turbo?

You blew a cac boot. Sometimes you can’t see the big tear because you aren’t looking for it and isn’t obvious when you pop the hood unless you know what to look for. With that much psi, sounds like a tire blowout but it’s just a jump boot. Then after that smoke out the stacks. I always cycle them out when they look old. You don’t change just one, you change them all. The tear could be at the bottom or back not in visual view and you can only spot it by gripping the boot sometimes

 

Any updates?

 

Likely one dropped and the debri took the other three out. And chewed up the piston and head.

 

Had one drop on a baby cat 3126b. Was on service rd. about to accel onto interstate. Bang, rattle, and a ton of blue-white smoke. Aborted to the right with it in neutral and clutch peddle to floor. It actually idled till i came to a stop and then it locked up solid. When Cat tore it down they found one dropped valve in #3 and it had chewed up the piston bad causing the lockup and a chunk of it went thru the turbo. All in a matter of a minute.

 

Yep. First time for me and hopefully the last. I learned that no matter how well you maintain an engine or how gentle you treat it if something gets tired its gonna just go! It had 475,000 on it.
The 3126 baby Cat is a throwaway block too. No wet sleeves so can’t change liners out and head was cracked like they usually do in this case. Turbo was scrap. Cost me $25,000 for full dressed ready to run replacement crate engine from cat.
Atleast the big ones are rebuildable. With yours If piston and liner are still ok just a new head, new turbo, make sure nothing is in the cac pipe. Drop pan check bearings. Change oil and filters and go. Unfortuanantly still at a cost tho.
