OIL NON-- RETURN VALVE
Preceding Work: Removal of timing gear case cover
1 Oil Non-- return Valve
Functions
The non -- return valve prevents the oil in the chain ten-
sioner from drying up. In other words, it stops oil-- return-
ing in order to prevent the oil in the chain tensioner from
getting dry. As a result, the chain tensioner can be acti-
vated with oil in itself.
Replacement Procedure
1. Remove the non--return valve using a pliers.
2. Insert new non-- return valve with hand.

It is very hard to remove the oil dipstick guide tube
without special tool. If it is not necessary, do not re-
move the guide tube.
3. Installation should follow the removal procedure in
the reverse order.
4. Check for leaks by starting the engine.
