    March 27, 2014. Problems and issues resolved. Four months and she's ready. New mechanic investigated for about a week. Oil pump and filter was incorrect. Leaking oil by oil cooler that mounts to block. The Etech and the E7 appear to have same oil pump. However, Etech pickup and discharge are opposite of E7. I needed a 12 tooth but had a 13 tooth that created the low oil pressure. Watched quite a few mechanics scratching their heads. The new mechanic took the challenge and solved her problems. Thanks to all for your advice it sure helped. Now I'm off to hit the road. Richard

    was reading your response and was not understanding how to pressurize with external oil pump were do u get the oil pump from or do I use my oil pump and what is the best way to do so

    Pulled two main bearings, one has hole and groove in center, one has offset hole and groove. Are there two different types?
  5. Richard Surman
    I just tore it down, have one lower main bearing in hand. Has noticeable groves, and a few burrs, less than 300 miles on these bearings. Top appeared to be fine. I have yet to check other bearings. Did plastic gauge and measured six thousandths. Mechanic does not have old bearings available for comparison.

    we already checked oil pump o ring and checked gasket the other mechanic still say cam bearings any other sugestions

    I pulled main bearing down and did a plastic guage 6 thousands on the bearing clearance is this ok or to much lost at what to try next

    I checked the oil pump and made sure no debree and gears aren't broken on new pump also blocked off hoses to jake brakes I was wandering how much oil should be getting to the rocker arms and vales it seems like very little to me I also installed relief valve or by pass spring in filter housing is there anything else that could cause low oil pressure after 15 minutes of running seems as soon as oil get warm oil pressure drops

    No fuel in oil. Mechanical and manual oil gauge used. Changed oil sensors, oil pump, new oil pressure regulator, warning buzzer comes on within 15 minutes of truck running and shuts down. truck doesn't run long enough to check brake. blocked Jake brake, no change in psi. Rocker arm caps aren't leaking, Mechanic called said he felt only thing it could be was cam bearings.

    2002 CX613 Low oil pressure. Mechanic can't seem to figure it out, Any ideas? This is a never ending story. . . Purchased truck in Memphis while driving it home about 300 miles I discovered oil in water. At that time oil pressure 60 psi. Brought to mechanic, did In Frame. brought it home thought we was good to go. Started it up went down the road a few miles and oil pressure dropped. Cold start 20 psi, running drops to 18. Mechanic has put new rods and mains, head gasket, new sleeves, new oil pump, new accessory shaft, new bypass oil pressure regulator , rings, checked Jake brakes, checked rocker arms. Now mechanic says its the cam bearings. Cold start 20 psi 15 min later 18 psi engine shuts down. 8 weeks later no solution. Picked truck up and now she sits. Anyone had this problem?
