Severe oil leak on S70 glt

RDR89 · Post by **RDR89** » 13 Sep 2017, 22:44

I located where the oil is leaking from but do not know what I am looking at. It is not the turbo seals. It is coming from a white plastic looking gem five inches forward from the turbo seals coming out of the engine way up there above the front axel.

I am sure this is an easy question for experienced Volvo wrench turners. My first Volvo so any help to get this silver beast going is very appreciated.

Thanks, Brian

Inside the red circle is the coolant tube and coolant hose.

This is the back side of the engine, are you sure the the valve cover is not leaking? There is not much in the back of the engine.
There's the camshaft seal on the side, turbo, oil feed and oil return to the turbo, and the valve cover that can leak oil.

Ok, I suppose the leak could be coming down from the valve cover. I am letting the heat shield cover bolts soak over night so I can get a better look tomorrow weather permitting.

I thought the turbo gaskets were where I have the green circle.

It looks like it is coming out of that place I have in the red circle. Really drips when it is running. I see what you are saying. Hard to tell from looking straight up.

You've got the turbo seals right, in green.

I'm not sure what that item is, I'll try find a better picture of the engine for reference

Is that a banjo bolt?

The pipe circled in green is the turbo oil return. That gasket leaking is pretty common. If you replace that, make sure you replace the o-ring on the end that goes into the block.
Can't tell what that is in red. I'm not aware of any oil lines in that area.

It is my opinion that the cam cover (they do not have valve covers) on these do not leak. If it is leaking, it's been leaking since installed.

If the leak is on the drivers side, higher than the axle, it is likely a rear cam seal.

It's actually very likely a cam seal is dripping down, totally forgot about that. Got caught up in where the picture was taken. Check around the cam sensor and distributor cap for oil.

Thank you for the comments and videos with Robert. Looking at the passenger side there is oil build up and on the side as well. So looking at the cam seals now as a possibility. I am cleaning it now.
