Engine oil filter internal oil circuit 
diagram 

•  The oil is pumped to push open the 

check valve and into the filter where 
it goes through the filter element into 
the main pipeline.  

•  In the case of clogged filter elment, 

the engine oil will push up the filter 
element to actuate the relief valve, 
which opens and reduces the engine 
oil pressure. And then the engine oil 
pressure switch is actuated and the 
engine oil flows onto the crankcase 
oil tray; meanwhile, the engine oil 
pushes open the safety valve to flow 
directly into the main pipeline and 
the crank shaft and cylinder cover 
assembly can still be lubricated.

1. Unfixing 
(1) Jack up the car 
(2) Detach the engine oil pressure switch 
fittings.  
(3) Unfix the engine oil filter (see 9-
Engine/Lubrication/Engine Oil Filter – 
Unfixing).  

(4) Unfix the engine oil filter fittings off 
the cylinder body.  
(5) Take out the engine oil filter.  
2. Fixing 
(1) Check and clean the sealing surfaces 
of engine oil filter.  
(2) Replace the engine oil filter seal 
(Figure 97).  
(3) Fix the engine oil bracket fittings 
with a torque of 28N.m. 
(4) Fix the engine oil filter (see 9-
Engine/Lubrication/Engine Oil Filter – 
Fixing).  
(5) Connect the engine oil pressure 
switch plug.  
(6) Lower the car.  
(7) Start the engine and check for any 
leakage.  
(8) Shut off engine and check engine oil 
level.
