Just yesterday when I moved my car for a wash I noticed the floor got oil stain. Thought it was coming from the bottom oil pan. Did Google abit I found out the possibility to leak from engine gasket so I check again today.

Gotcha! Oil level was at the middle of max and min. Looks like leak already sometime. Leak at the floor might becuz I revved the car few days ago...

Not dripping from bottom pan or engine block ? This photo looks like from head gasket only. You can change head gasket, or just clean it if you want. Cheapest solution topup some oil weekly/monthly. No harm no issue this condition.

#3 can open, this screw nut is just to hold the black plastic cover only..

after open u can check sparkplug area if thre are oil stain..
or the oil cap if leak from there or not.
then check the whole top piece where join to the block.. any leak or not

**Add on, from the looks of picture #1 & #2, the leak seems to be gasket.

I certainly do hope the leak is not coming from timing chain. Yes, this is out of my expertise.

Not bottom pan. Engine block...hmm... Tomorrow I might have to rev it up again and confirm leak location.

Ya. But then I have to know the bolt size because I don't have a spanner set.

Use the adjustable spanner will do as well... it's a 10mm socket.

If its the valve cover gasket leaking, its best to prepare
- a box socket set (you probably use size 8, 10 and maybe 12),
- a new valve cover gasket
- a mallet or something to pry the edge of the valve cover
- rags or old newspaper to wipe excessive oil
- a razor blade/utility knife/pocket screw driver to remove bits of broken gasket
- RTV to just dab the corners to prevent it from being dislodged when you install it
- pliers to remove the PCV hoses if yours have it

Torque wrench is really needed if you plan to remove/reinstall the cylinder head.

Just ask the mechanic to do with your next oil change. RM120 was the price I paid for last time IIRC.

Visited workshop today but still not open. I think I will buy engine oil first. Last oil change was 5W40.

Sifu2 recommend semi or fully? Vios second gen 11 years already I think.

Seems like just a normal valve cover gasket leak. It is a simple fix.

Vios recommended oil is 5W30. Best you go for Fully Synthetic.

from photo doesn't look like that was the major cause of leak until half oil gone. leak from top cover is minor normally. won't cause oil to be halved. what I suspect more is your engine makan oil already, that mean your valve rings need to be changed. to check just start engine and see tailpipe got smoke or not. or revv a bit and see are there smoke? if got smoke then that's where your oil gone to. just my 2 sen.
