My car has leaked from the distributor area on the back of the head. As yours is a Turbo and suspect the breathers might need checking it might be the return pipe from the turbo. The pipe goes into the block right by the oil filter.

Thanks. My leak is definately oil based since when I tried to wash it off the water it just beaded on the top of it. Theres definately something leaking at the turbo side of the engine, theres been some evidence of leaking towards the front of the engine at the turbo side but this didn't seem to amount to much and I suspect it might be something different this time and could be the turbo return pipe as you say. Think I'd need to take the undertray off for a decent look since it looks like it pools a little on that prior to dripping off the back...

Anyone know of any guides to do the breathers on the red block turbos? (the FAQ gives some hints but doesn't seem much help to an newbie like me). The Haynes manual also doesn't seem particually helpful, it just shows a picture of the engine with a hose running along the top??? but I can't say I remember seeing quite the same on my engine... Got an old car mechanics service bay article on a 940 turbo and that mentions that its at the back right of the engine under the intake manifold? Doesn't look particually accessible under there!



Doubt I'll have the time/energy to muck about with it this weekend, especially since the C70s due an oil change. Hopefully if I get the breathers cleaned out/changed they the oil leaks might stop since they must only be slight to not effect the dipstick. I'll probably be doing a tip run at the weekend and I'll see if its puffing out the dip stick tube.
