One of our friends has put in an isuzu 4jb1tc in a mm 550.The original dip stick was missing,so another one from an isuzu 2200cc engine was used instead. Now when the jeep is driven even for a short distance the engine throws out oil from the dip stick pipe.There is no blow back from the tappet cover inlet or from the crankcase ventilation system.Even the dipstick gets pushed out by the pressure.The vehicle has not done even 50 kms till now. Please help.

Manual says

Inspect any clogging up of the oil cooler elements has occurred, when the oil cooler
unit is detached from the engine, pour oil or light oil into the oil cooler element through the inlet port,
and check to see that it flows away from the outlet port. However if the oil cooler unit is attached to the
engine, the following procedure is recommended;
1) Check oil gallery pressure at idling speed
If the oil cooler element is clogged up, the oil gallery pressure reading will be increased 1 to 2 kg/cm2
(100 - 200 Kpa) over the normal figure. This increased pressure is due to an oil pressure loss in the oil
cooler element.
2) Check the oil temperature in the oil gallery
If the oil cooler element is clogged up, the oil temperature in the oil gallery will be higher than normal.
If the engine operates at high speed, or is heavily loaded, the oil temperature will increase rapidly
