Greetings, everyone.I hope everything is good.I resolved the issue with my oil filter housing last week, and the oil leakage from that region ceased.My additional oil leak is located at the front near the chain cover.It seems to originate from the upper corner of the bottom timing chain cover.If it is the superior option, it can be accomplished; nevertheless, it seems that the inferior option, which is challenging to rectify, necessitates the removal of the sump, as shown by most videos.It is really a little leak from top to bottom. My previous mechanic performed the inadequate installation of the chain slide rail.Is there any silicone I can use from the top corner to prevent the leak without removing the cover?Thank you.

Verify that the issue is not related to the O-ring of the turbo oil feed line. It is rather typical for failures to occur, resulting in oil leaks and creating a mess at the front of the engine.

It is unnecessary to replace the line itself; nevertheless, it is essential to replace the other components, including the banjo bolt, since it is a one-time use item and has an updated check valve that the original lacks.

I changed the O-ring almost two years ago, and it now seems intact, with no leakage from that side.
