Thanks for the information.

Did you replace the camshaft bearings? Do you see oil flowing up to the rocker arms? Was the oil cooler replaced? Is the oil level rising or smell of fuel in the oil? (this could be the cause of the original failure) Did you determine the cause of the original failure?

Any of the items below can cause low pressure.

Dirty Engine Oil Filter Or Engine Oil Cooler
Check the operation of the bypass valve for the filter. Install new engine oil filter elements, if necessary. Clean the engine oil cooler core or install a new engine oil cooler core. Remove dirty oil from the engine. Put clean oil in the engine.

Diesel Fuel In Lubrication Oil
Find the source of the leakage of the diesel fuel into the lubrication oil. Make repairs, as required. Remove the lubrication oil that has been contaminated with diesel fuel. Install new oil filters. Put clean oil in the engine.

Too Much Clearance Between Rocker Arm Shaft And Rocker Arms
Check lubrication in valve compartments. Install new parts, if necessary.

Damaged Oil Pump Suction Pipe
Replacement of oil pump suction pipe is required.

Improper Operation Of Pressure Relief Valve For Oil Pump
Clean the valve and the housing. Install new parts, if necessary.

Damaged Oil Pump
Repair the oil pump or replace the oil pump, if necessary.

Too Much Clearance Between Crankshaft And Crankshaft Bearings
Inspect the crankshaft bearings and make replacement, as required.

Too Much Clearance Between Camshaft And Camshaft Bearings
Inspect the camshaft and the camshaft bearings. Replace the camshaft and the camshaft bearings, if necessary.

Too Much Bearing Clearance For Idler Gear
Inspect the bearings and make replacement, as required.

Orifices For Piston Cooling Jets Are Not Installed.
Install the orifices for the piston cooling jet.

Have you inspected or tested for any of the above items?
