All the cats I've driven run up just short of 240 on the oil on a long hill. I've never lost an engine so I'd assume that's normal. I've never seen it cross that 240 line though.

I have a 2002 379 with a 6nz c15 475 horse motor it was just rebuilt about 1000 miles ago it has a pdi stage 1 turbo and a marine cam shaft and 5232 trim codes and after 300 mileage it has blow by so bad it looks like its on fire it is missing real bad. I called the mechanic that did the work and he said that's normal and at mile 1000 it started knocking and shaking and missing all at once it has since been towed home for him to look at. I stopped at cat and they said the blow by is something inside of the motor. Does anybody have any ideas what might have went wrong. Please help.

Can that happen with bran new parts. This all started after I pulled my first mountain. I watched all temps and nothing got to hot and I always precool

The Cat parts or aftermarket? They could fail from improper installation

All parts are from cat.

I have been running that trim code for 1.5 yrs and no trouble. Cat put them in and cat told me they were safe to use and that would not hurt anything.
