Turbo going bad? C12

Maybe your wastegate is starting to seize, ,,,get the pdi turbo,,,and tune,,,you won't regret it!!!!

 

maybe it blowing though the air compresor out the spitter valve mine was doing that every time i got in the boost it would go to 35 then drop to 30 then pop off keeped doing that

 

Check the turbo mounting bolts too. We have 2 C-12's and both of them had the turbo's come loose several times, we ended up double nutting the mounting studs. May not be your issue, but an easy check.

 

That really doesn't sound like a bad turbo to me. The turbo itself is a pretty simple device that doesn't really have intermittent problems. The waste gate could be acting up, but it sounds more like a fuel problem to me. Possibly a restriction somewhere, like filters starting to plug up? Before I condemn the turbo, I'd find someone with Cat ET to go for a ride with you to see what's going on when the boost surges like that.

 

Doesn't sound bad to me . Sounds like leak or lack of fuel

 

I would suggest checking the solenoid for the wategate first. These engines have an electronic wastegate set up and can have issues with functioning properly.

The best way to fix it is reprogram the ECM with a earlier C-12 file that eliminates the wastegate from the programming. This will advance injection timing, improve Hp and throttle response, while increasing fuel mileage. You also need to replace the stock muffler with a Donaldson M100463 for a much freer flowing exhaust set up.

I'll send you a PM
