I removerd centrifugal filter, cleaned all filter unit with solvent, changed oil and start engine!

over 70 PSI on laptop! Ok, I tried mechanical gauge - the same figures.

I did test ride, but I cant warm up bobtail truck, so in monday I gonna find heavy trailer for test

First gen paccar engines had a bad oil consumption due to faulty guide deals.

I had this problem on a 2010 model mx13 it was the bearing on the bottom of the centrifugal filter

Check history and see if an oil change was done recently. We had one acting similar and the PM guy had left little bushing out of centrifugal filter

There is no little bushing on the centrifugal filter of a mx13 there are only top and bottom bearings
