TIAGO

1.2L REVOTRON ENGINE

2. Oil Filter :

The oil filter used is a "Spin On Type" fitted.

The main function of oil filter is to filter all

contaminants that get ingested into the engine,

along with traces of worn out metals from

bearings and other internal parts.

The oil enters the oil filter under pressure through

the holes on the perimeter of the base plate.

The oil then passes through the filter element

where it is cleaned, and then flows to the central

tube and back into the engine, oil gallery.

3. Oil Strainer :

The oil strainer is fitted to the oil pump along with

O-ring, through which the oil is drawn from oil

sump and supplied to the oil gallery. The strainer

acts like a filter and blocks the contaminants from

entering the oil pump.

4. Oil Pressure Switch Sensor :

Oil pressure switch sends the signal to low oil

pressure indicator lamp provided on the vehicle

instrument panel by closing the circuit to ground

when the oil pressure is low / below the optimum

value.

5. Hydraulic Lash Adjuster (HLA)

Hydraulic Lash Adjuster supports the pivot end of

the rocker arm while automatically controlling the

rocker arm position to keep it in contact with the

camshafts and valve.

The range of the hydraulic lash adjuster

accommodates engine build tolerances; hence no

adjustment is required during engine assembly. At

all engine working conditions it maintains zero

clearance between rollers rockers and valve stem.

Maintenance

Hydraulic lash adjuster uses Engine oil pressure

for its operation. In case of a freshly assembled

Engine, do not run for a long time; there are

chances of valve train noise / tappet noise

appearing when the engine is started.
