I was shifting hoses around today so I could get to the fuel injectors on my surf (and then later cracked the leakage pipe so I'm now leaking diesel but that's another story!) and I noticed that inside the big metal hose on top that leads into the turbo, with "EFI turbo diesel" etc. stamped on it, was quite a lot of greasey oil residue.

I'm fairly sure that it should be a lot cleaner in there! Is this something to do with me not leaving the turbo timer on for long enough when I turn the engine off? Or is it more likely that oil is seeping in there somehow.

Is it gonna cause me any problems? For those that like pics, the missing bit across the middle of the image below is the hose I'm talking about!

Install an oil catch can in the hose that goes from the rocker cover to the black crossover pipe.

If that does not fix the problem then your turbo seals are FUBAR.

mine gets oily in there too, it gets sucked up from the breather that goes from that intake pipe to the rocker cover

not a big deal i don't believe? as smurf said an oil catch can should fix the problem.

Cheers all. I've actually just dropped it off at the garage ... Daneo ... did I just see you parked outside that garage? Similar looking ride but had a 4wd upgrades sticker on the front

nope. there's a lot of pre-90 surfs round Christchurch that look similar to mine though

Haha true, with waimak mud all over them!

surfs have a fault in the breather filter under the rocker cover. there is a part from toyota that helps, its just a pickup extension. it replaces the breather pipe that come out of the rocker cover.
however with the amount of blowby these old motors get you still get oil blown out. so a filtered catch can is highly recommended (also it will pay to plumb a drain from catch can to sump unless you want to empty catch can often). that will cut down on the amount of crap that builds up in the manifold.

Is a filtered catch can something you can specifically buy or is it more of a "Blue Peter" job that you make yourself out of toilet rolls and sticky-back plastic?

noone seams to sell filtered catch cans so usually have to buy one and fit filters into it (wirewool etc). the filter is fairly important otherwise oil just gets blown straight out the outlet. also make sure it has big enough connections. most diesels are 10-12mm while a lot of cans are made for petrols (6mm).
