Hi guys, i have an oil leak through the engine oil cooler's gasket, how big of a job it is? i have a pit in the garage so i can work from below if necessary. I saw in RAVE that the turbo must be removed and if it's so i'll quit. If it's possible to do it without removing the turbo i'm up to try. I was able to replace the ACE pump, water pump, alternator and the aircon compresssor myself so if it's not harder i'm ok. What are yours thoughts ?
 
What are you worried about when it comes to removing the turbo?
To remove the exhaust manifold you have to undo connections to the turbo be able to get to it. I did that and found it no bother at all.
I've just read up in the Haynes manual, removal and replacement, it is so easy they only give it about a third of a page.
Unless you know something I don't I really would encourage you to not worry about it.
(Can't believe, for once in my life, I am actually giving you advice!)
Other stuff you have done looks much trickier.
Best of luck with it.:):):):):)
 
I have the cooler gasket, new o-rings and gaskets for the centrifufal filter drain pipe but i'm missing that exhaust port gasket to the turbo and can't find one locally that's why removing the turbo mixes up my plans as i have to wait untill next week for one to arrive from UK:mad:

unless its broken reuse it
 
I'm too scrupulous with my beloved to reuse a gasket with air "filling" (i dont know how these are called in english):confused::cool:... i reused one once at FPR which is the same type and it leaked, i'll wait for the new one to arrive
 
Hi Fery
I also removed the turbo 2x and no issue. Only problem was to remove the exhaust from the turbo as it is quite difficult to access the nuts. I purchased a specially shaped tool (like attached) as I remember size 15 which also makes the other turbo nuts (manifold to turbo) removal easier.
Regarding on gasket, should be available for local turbo specialist (for example when I took my turbo for checking to a local shop they gave me set of gaskets from the shelves)

If you are talking about the third nut under the turbo/exhaust joint, I found a 3/8 socket and extension combo worked fine, you just need to fit it carefully by touch.
didn't need any funny spanners. though i can imagine them coming in handy for lots of jobs!:):):)

they are just multi layer ,it have to be broken to leak or fitted badly,its common to reuse those gasket types

First I tried this also from underneath but no chance, broken after some harder attempt.

Even with the above bended wrenches first I needed also "help of a hummer" :)

But if you have already a decat downpipe which has smaller flexible connection then you can better access it from underneath but if you still have the original pipe straight extension will not work from underneath due to the big flex connection (at least we could not put anything on)

I'm beginning to wonder if it makes a difference what order you do things in. I did all the work from the top and yes, mine is a 2000 MY so has no CAT. But I didn't need a flexible like in the pic. Cannot honestly remember if I used a U/J or not. Some times wish I filmed everything cos there are things we do that don't seem a problem yet others subsequently seem pleased to see them, if they exist! the metal flexible from the turbo can be moved with a bit of effort, and this helps. Did not need to use anything other than its flexibility to remove the exhaust manifold once all the turbo connections were off.
Dunno what year sierra's is.
 
I think we are both right as I just recognized one big difference in my, Fery's and your case.
Our car is LHD and yours is RHD.
So we do not have much space to work around the turbo, this is why I found the bended wrench very useful:)
And also tried to access from underneath before...
