9.9 Engine oil pressure is abnormal
(3) Eliminate the dirt that restricts the eng-
ine oil, and clean the oil passage of the
cylinder head.
The cause of the fault
1. The engine oil lack of pressure or the pressure is too low
(1) The engine oil in the oil sump is not
enough
(2) The engine oil becomes thin
(3) The oil pipe is broken, pipe connector
is loosened, and there is oil leakage in the
oil pipe
(4) The gap of the engine oil pump is too large
(5) The plunger of pressure-limited valve
isn't quick and the spring is broken or
distorted
(6) The drive pin of engine oil pump is broken
(7) The fit clearance between the main
bearing and connecting rod is too large
(8) The plug of the oil pipe is loosened
(9) The engine oil air filter is clogged by
the dirt.
(10)The engine oil filter is too dirty
(11)
(12) The engine oil manomenter is broken
2. The engine oil pressure is over high
(1) The adjustment of the pressure-limited
valve is not right, and the engine oil can't
return
(2) The air temperature is over low, and
the oil viscosity is too large
(3) The lubrication at the camshaft neck is
not good
Elimination method
(1) Refill the engine oil up to the specified
level
(2) Choose the specified fuel type
(3) Replace or tighten it
(4) Replace it
(5) Replace it
(6) Replace it
(7) Check, adjust or replace
(8) Check the plug
(9) Check and clean air filter
(10) Clean or replace the element
(11) Check and replace
(12) Replace
(1) Check and adjust
(2) Use the specified fuel type, its
viscosity will fall automatically
after warming up
