Hi my name is***** will be glad to try to help. What is the complete engine model and serial number? Check the crankcase breather vent system that it is not plugged and if okay and actual blowby verify if it is in specs with a blowby meter, compression test, or cylinder leakdown test. Cat owns Perkins and instead of compression testing they usually measure blowby instead with a meter. Check the turbo to see if there is signs of dusting from dust getting into the turbo and if the compressor wheel is damaged or has oil indicating a turbo problem. Other wise the oil pan needs to be removed and the cylinder walls inspected for scoring/scuffing, etc. and oil filter cut open and inspected for debris indicating internal problems. Let me know
thanks for the update. That cylinder and rod is your waste gate. Make sure that is not seized and will open and close the flap on the exhaust. That responds depending on current operation conditions. With a vacuum pump ( automotive) try to test the diaphram for leaks and replace if leaks are found. also check that the flap on the exhaust moves and is not seized. Let me know
Thanks for the update. Keep me posted.
Thanks for the update. What parts did you replace?
That is a turbo waste gate. its not supposed to continuously move.... 1where are you seeing this bowby? Blowby is compresson leaking past the piston rings. There is no blower on this engine. It has a turbo with a wastegate.
If you are correct in stating blow by..... Bowby can only be corrected with rebuild with new pistons and rings etc
If the waste gate is stuck closed you will need to replace the turbo. Pleasure to help
