I'm not expert but I suspect oil may be comming from that sensor above or that round screw(on top of the engine part)?? What do you think?

Could be your valve cover or disty

if you talking about that lil gold looking thing to the right of the hose...i have the same problem...i replaced like a bunch of seals cleaned it all up real nice...now its back again...i need to know the answer to this too...good post

that gotta be a sohc right

yes, it's sohc.

BTW left and top side of the engine are clean, only this part on the pic is oily.

like Custom suggests...

it does appear to be a valve cover leak though, even the tiniest streams of oil can become very messy like in the photos you've provided and unless you seal those valve cover gaskets with a silicone bead, you can probably expect them to start leaking within a year or so...

I DON'T think oil comes from valve cover. Today I cleaned the oily parts and found oil on 2 spots:



The left spot seems to come from the pipe above and I'm not sure how oil got on the right spot (maybe also from that pipe or that strange round screw).

unfortunately, the "pipe above" the left red circle is a coolant line...

Than that pipe is ok. Somewhere on that area around the pipe oil is leaking but I can't see where exactly.

The head gasket is a possibility. They are composite gaskets with o-rings on them for oil to drain down to the block. They leak eventually and that's usually where the oil runs down. The red circle on the trans is a vent tube. It's not likely gear oil would be coming out unless the trans temperature was pretty high or the fluid level is way overfull.

The round screw on top of the hose is a coolant temp sender. Only coolant flows past it. Hope this helps.

I noticed on leaks that I've seen on cars before, that the location of the leak is cleaner than the rest of the engine... like a little gap in the grime of the rest of the engine. Usually, this is around a gasket, where two parts meet. Take a good look at your engine, look for places where the dirt and oil is missing. That could be the leak.

Thanks for the feedback, I've cleaned the engine and oil first appears on red arrows:




Since engine rebuild is not an option I'll put silicone all over this binding (head gasket?) and tighten the screws if necessary. I'll also pour in oil additive for leakages.

As for this one I have no idea where oil is comming from. Please advise on this :

Sure looks like the head gasket just like everyone else is saying. The oil around the transaxle vent is engine oil, mostlikly from the head gasket too. If you have over heated your engine in the past, it would have warped your head, causing the leak. Remeber they are aluminium heads that warp at just a little heat.

Yes, I had over-heat when my radiator broke down.

Where do I put silicone in the 2nd pic?
