Hi guys,

Just want some thoughts about this oil leak I have in my yd25 motor (2009 model). It seems to be coming from what I think must be the timing chain cover. It's a slow weep and has been like it since I bought it earlier this year but I would like to deal with it soon.

Am I right in saying that cover at the front of the engine is the timing chain cover? And does much oil get circulated behind that cover? Do you think just the gasket for that cover needs changing or might it be something else leaking nearby?

Seems to be weeping from the bottom of the big cover at the front (that has the caution egr hot sticker on it) onto the smaller plate below it that has "layd1" printed on it as seen in the attached pictures.

Is this a "common" place to get a leak on these motors or do I just have a one off here?
