Oil Control Valve (OCV) also known as Oil solenoid or VVT solenoid.
At first I thought it was the OCV oil ring…but since the leak came from the socket…for sure it’s the OCV itself leaks…
Symptoms : A bit slugish during VVT engage…
Solutions : Replace OCV

Physically, the original oil filter (made in Japan) printed lettering must be clear, bright and sharp. Plus the filtering look like the picture below.
Some imitation oil filter are not bright enough and even the text is blurred. The filtering system are soo different and have a few type, with steel, not vertical and so on. So be careful, the price is not that much different, but the most important thing is the filtering system.
Original Toyota Oil Filter, C6
The filtering , the original one, should look like this…
There’s also a new mentioned that C6 will stop production and will be replace with E2, made in Thailand. C5 will be replace with E1. Darn…the worst part is, the E2 model are wrapped up with steel kind of filtering, have to do some investigation and comments on this E2 that I’ve never used before.
E2 Oil Filter, made in Thailand
But this filter have a bypass valve..
If you wait too long to change the oil and oil filter, there is a danger that the oil filter might become plugged. To prevent a plugged oil filter from starving the engine for lubrication, oil filters have a built-in safety device called a “bypass valve.” When the differential pressure across the oil filter element exceeds a predetermined value (which varies depending on the engine application), the bypass valve opens so oil can continue to flow to the engine. But when the bypass valve is open, no filtration occurs. Any contaminants that find their way into the crankcase circulate throughout the engine and act like an abrasive producing accelerated engine wear.
Another option, is using the Perodua 15601-00R01 oil filter…just knew that we can use perodua oil filter…
But…i’m not quite sure whether it can be used on 4AGE or not…still looking for answers…

Chemlube Motor Oil, specification…Property and Functions of Lubricant Base Materials :
METALLIC COMPABILITY Affinity to stay on metal surfaces to prevent Friction
HIGH VISCOSITY INDEX Give high oil stability in hot operating conditions during traffic jams/high speed driving giving complete lubrication
HIGH DETERGENT PROPERTIES Prevent oxidization& sludge formation keeping engines clean thereby promoting engine efficiency and better fuel mileage.
LOW VOLATILITY Maintains consistent oil viscosity(thickness) through variable engine operations providing for optimum performance consistently.
SULPHUR CONTENT Low sulphur content prevents sulphuric acid formation which causes engine corrosion especially useful in diesel & turbo engine
BASE MATERIAL COST High cost deterring wide lubricant market usage
So the first one…my review, using 10W 40 Chemlube motor oil…
A) METALLIC COMPABILITY - Affinity to stay on metal surfaces to prevent Friction
- this one not to sure how to check it out…heee…
B) HIGH VISCOSITY INDEX Give high oil stability in hot operating conditions during traffic jams/high speed driving giving complete lubrication
- ahaaa…this one…yes it surely did, high revving during afternoon is really-really excellence…better then my previous engine oil…
C) HIGH DETERGENT PROPERTIES Prevent oxidization& sludge formation keeping engines clean thereby promoting engine efficiency and better fuel mileage.
- last night, did a little check-up on my engine…open up the oil cap…to my suprise…the head was cleaner then what I’ve expected…only after 1500km only…Chemlube motor oil really did thier job…
here are some picture of the current head conditions…after high revving…
Closer…engine heat also can be seen on the pic…heee
Even closer…you can see the spark plug "tubing" shines…superb…no more carbon deposit…
D) LOW VOLATILITY Maintains consistent oil viscosity(thickness) through variable engine operations providing for optimum performance consistently
- I suppose the oil are doing their job superbly…
E) SULPHUR CONTENT Low sulphur content prevents sulphuric acid formation which causes engine corrosion especially useful in diesel & turbo engine
- no more sulphur build up…as seen on the 3rd picture above, you can see the previous sulphur deposit build up…
- what is sulphur ? sulfur is an abundant tasteless odorless multivalent nonmetallic element; best known in yellow crystals;
F) BASE MATERIAL COST High cost deterring wide lubricant market usage
- another reason why I choose chemlube…expensive to produce maybe due to the ester base…
Conclusion…i’m very satisfied with Chemlube Motor Oil…this will be my engine oil…
So guys…what do you think…? I’m sure you will suprise with the results…try it…

Chemlube an Ester based motor oil, for me is the best…better then PAO and Mineral oil…yet Ester is the most expensive to produce…
- Esters are very stable at extremely high temperatures and are used almost
exclusively in jet engines. So when you use Chemlube, you are giving the
best to your car. Just like for the aircraft!
- a fully synthetic is 3200 PSI (the best in its class)
- can lasts up till 40,000km or one year
Some fact about Chemlube…
Chemlube is a multi-grade fully synthetic ester base motor oil designed
for long life use in cars, trucks, farm machinery, stationary engines,
marine engines and construction equipment.
While some synthetic motor oil use hydrocarbon (PAO) as their base
material, Chemlube use 100% organic ester (Base stock) for its motor oil.
Conventional 100% Synthetic super-multigrade lubricant (5W40, 5W50,
10W60…) use VII (Viscosity index improver) to boost their viscosity.
These viscosity additive tend to loose efficiency and shear when submitted
to extreme conditions. Since Chemlube motor oil use ester for its base
material, it benefit from the natural viscosity of synthetic ester thus
they need very little of such additives or none*.
Esters are very stable at extremely high temperatures and are used almost
exclusively in jet engines. So when you use Chemlube, you are giving the
best to your car. Just like for the aircraft!
Superior benefits of organic ester are:
Natural Affinity to stay on metal surfaces providing a thin protective
film to eliminate dry start-up engine wear which means easier morning
starts and smoother engine operations.
Very High Viscosity Index indicate a low viscosity change. By employing
Ester as the base for synthetic oil, Chemlube change the conventional
concept of synthetic oil. Ester are polar molecules that have the ability
to electro-chemically bond with metals, so as to maintain a continuous
lubricant film at high or low temperature. This in turn provided a better
resistance to thinning at high temperatures and thickening at low
temperature.
Outstanding Film Strength so it takes a lot longer for the oil to drain
completely off the bearings and into your oil sump. This prolongs engine
life and increase engine efficiency.
Strong Detergent Characteristic. Chemlube not only inhibits rust and
corrosion but minimizes spark plug fouling and carbon, gum and sludge
deposits. Ester itself is a natural detergent, it adheres naturally to
motor parts which dissolves and suspending harmful sludge, varnish and
carbon deposits which keep engines and lubrication ports cleaner and in
top performing shape.
