Hi guys,
I noticed oil leaks near the top of timing chain cover. See the photos. One from the front of the engine, the other from the top (near the air intake).
Last week there’s a message on the dash “low engine oil”. Sure enough the engine oil was lower than normal. And I top it off with 1L (on the 8000th km since last change).
1. I suspect the timing chain gasket must have leaked, and leaked out engine oil. Is this the case or something else?
2. Is this serious enough to go to the mechanic or the oil will plug itself out from leaking?

Thanks guys.

From the front. Oil leak beside the timing chain cover. I tested, it’s dried oil.

Thanks ES6T.
