Noisy Ticking .. Is it noisy tappets ?? After oil change ..

**Dezaremos** · September 26th, 2017 02:34 PM

Previously using Mobil Super 1000 15w40 and after that, Honda Vtec Lev 10w30 which are all Mineral Oil ...

Engine was ok and noise is normal ..

Change to Mobil Super 2000 10w40 Semi-Synthetic Oil .. Now the engine is very audible .. You can the valve tappets ticking ...

Is it a normal noise of semi synthetic engine ?? Will it damage my engine in the long run ?? Or is it only Mobil because some say Caltex Havoline Semi Synthetic offers a silent engine ...

Should I go back to Mineral Oil ???

Car is Corolla .. Engine is 1.6 4afe ...

Sabi nila hindi daw na-adjust ang valve tappets ng 4afe .. sa 2e lang daw yun ..

Go back to using mineral oil. Try "thicker" oil this time, 20w50.

Hindi naman knocking noise ang naririnig ko sir ... same fuel as before pa rin ginagamit ko .. mas audible lang ang noise ng valve tappets ngayon na nag semi-synth oil ako, dati sa mineral oil hindi naman ganito ka ingay ang tappets .. lalo nag pag operating temp na, tahimik na tahimik na ... pero ngayon sa semi synthetic oil, kahit operating temp na, dinig na dinig mo pa rin ang valve tappets noise kahit naka sarado ang hood ..

Synthetic oil has good detergent capabilities. Most probably, it loosened the "mineral" build-up on your valve train, hence the noise.

don't fix if it ain't broken LOL i mean why change to fully synthetic anyway?

funny i just saw my 90's corolla driving past earlier tonight, probably by it's 3rd owner. it's probably as old as your car. i never used fully synthetic on it

btw when was the last time you checked the valve clearances? paano ba adjustment ng 4afe? shim based?

It's no fully synthetic .. its just a semi synthetic oil ..

That's the problem .. all the mechanics and shop I've asked said there's no adjustments on 4afe's .. unlike the 2e engines that can be adjusted according to specs via shim ...
