i have a blue bird vision with 6.7 cummins i put a new turbo on it and took for a ride and i am now getting a code 555 crankcase pressure i click on the code and it wont give me a diagnostic tree can anyone tell me what the test procedure is not sure y it wont give me the tree
too much too copy i will "cole note" it for you key on the sensor should be reading close to 0(psi or kpa) give or take(if not bad sensor) check your tubes that exit the crankcase filter for blockage check oil level, then after that it gets into blow by caused by worn engine parts if you click on the other insite file on desk top you can the tree just select engine scroll down and find 555, the last update screwed the short cut to code reading (path is wrong)

In fault code search just loose the 0 (555) Like Bluenozer says tubes that exit the crankcase filter just do yourself a favor and just replace cause some air will come. If you want to see just take the oil cap off the top of the valve cover put a oil absorbent rag on top and take for a ride and see if it goes out. Just went through this a month ago.
i went on insite and searched threw all the codes and and 555 wasnt listed but i will check the hoses and i will just replace to crankcase filter i believe its orginal thanks again guys
should be a small vent tube that comes off the LH side of motor 1/4 in hard plastic looks like a y behind the fuel filter. you will see the 1 way check valve in it. goes into valve cover on lh side
code 0555
