I have been working on my service truck again , fixxed a fuel leak found and repaired two small boost leaks . Had a hard start/no start after shutting truck off when road hot ( this is fixxed it was timing speed sensors in the back of front cover)..
So i decided while im doing all this i will put guage on intake and fuel, fuel pressure is perfect. But most i can make is 13 psi boost it should be 20psi. Looked over cac cooler no aparent cracks in the usuall spots , i need to pressure test it to verify but ran out of time .
I suspect the wastgate in turbo is not sealing or is falling apart, i suspect this becuase everyonce in a while while on the road i will get into the throttle and all of a sudden the turbo whine will get what seems like twice as loud , its real noticable when you can hardly hear it to begin with.
The question is this a common problem on a higher mileage 3126e 210 hp at 2200, 605 torque at 1440 , if someone really wants the serial number i will venture out and open the hood . The prefix is CKM. Also i tried pinching off the hose to wastgate that didnt help .
