Oily turbo

[lacroupade]

OK, I've got modest oil blow showing at the ends of both the hoses to the i/c, both before and after.

I'm not quite sure where the EGR system squirts its shite back into the circuit so can't decide where the oil might be coming from.

The obvious culprit I guess is oil seals in the turbo, but is that necessarily the case?

If it is, given there are no other symptoms/problems, is the turbo serviceable as far as seals go or do I need to get a replacement?

If I do, whats the likely cost? No point in buying s/h if a new one isn't too crippling.

If its not, what else could be the problem; its not using oil up at any noticeable rate so I'm not overly worried (plus its the wifes car LOL).....but it clearly need nipping in the bud.

And I guess given the negative effect of oil sludge buildup on cooling, I need to flush the i/c when I do the job - I forget who did it recently but is petrol OK to use or do I need an industrial solvent of some kind?

Cheers m'dears....:thumb2

MY van was using oil at a worrying rate, I noticed excessive oil at one side of the IC the other side had new clips. I cleaned it all up and replaced clips and bingo - no more oil loss - not a drop and its done about 2.5k miles since!

Weird....I was wondering if it might be due to a historic overfilling event or something?

Did you watch Paddy Doharty last night? what a card!

I did, and i was pleased at last to see and actual 'Gypsy' wedding :thumb2 Lovely young violet, tasteful dress - full congregation - tasteful reception - hard working young woman - that's what it's all about :thumb2

I hope i don't regret typing that when the comments start to fly :doh

so back on topic, clean it all up replace the clips on the IC hoses and it should be fine :thumb2

But Paddy will be a target; taking delivery of his new twice-yearly Audi A4 convertible :augie LOL.

But I guess I'll have to flush the i/c cos if its lined with oil it won't be very efficient....bloody cars :doh

FWIW: when I took my inlet path to pieces there was a fair amount of oil floating around too.
Don't think it could have been the turbo as the previous owner had a new turbo fitted by NISSAN
Same thing here, cleaned it up re-fitted and has been fine for the last 6000 miles...

Well thats reassuring - ta lads. :thumb2

yep, a target alright, but enough of that :augie

when I did mine there was virtually nothing oily in the IC just a little around the entrance and exit (smutty comments are allowed) I was prepared to wash it out, but it just didn't need it. I just cleaned all the oily gunk from around the pipes and general area with brake cleaner and then fitted new shiny jubilee clips -job done

Do they have to be shiny ones?

Who was it had an i/c full of crap recently? Intrigued to know what was going on there...I might just have it off anyway. Then I'll fix the intercooler LMAO!:doh

you never miss an opportunity - do you? :lol

yes they have to be shiny, they wont work properly otherwise :augie

I'll put the matt black 'stealth' clips back on the shelf then



Well somebodys got to having a larf haven't they

 

[(RIP) PLANK]

while you have been practicing your skill with innuendo - you could have had them clips changed :augie

















crack on! :lol

hello again,
we at work had this all the time on engines, cured it by not using multigrade oil.
try straight sae30 oil, if manaul says it can take it.
reduces blow by, the multigrade oil contains VI's which shear, this causes problems with viscocity, and blow by.
when running do you get a steady vapour out of oil filler cap and when warm out of dipstick?
if so with straight weight oil, i bet you get very little or none.

Good tip, I'll give it a bash thanks!:thumb2

 

[makeitfit]

Ah well\you see I was having some snifters earlier and have just remembered it was ME
My I/C was like an empty marmite jar when I had a look in it
Cleaned with petrol and then lots pressure washer shampoo and flushed with clean etc.:thumbs
Then I took the blow by pipe offt he intake pipe and blanked said intake pipe off
The blow by pipe now spits out whatever it wants into the wifes old alu water bottle :lol
Keeps the i/c clean and so actually able to do some chilling and keeps the wife busy looking for her bottle :lol

Even on the TD without the intercooler, the rubber pipes that go across the rocker box cover after several years have a very fine oily deposit on the outside, like some one spayed a small amount of WD40 from 2 feet away, so we are talking very little.
It's not from the hose clips but actually through the rubber, the wife's picasso is the same.
The rest of the engine is nearly as clean as the day it came out of the factory.

I removed the pipes looked at the turbo fan with a torch and mirror and the inside of the aluminium pipe, and everything was like new, so I think the turbo pressuer (1bar max) is pushing what mist there is through the rubber.

Am I worried, no :thumbs
It has always been the same after 16 years of ownership.

due to internal heat of turbo, if you did find oil in it, it would be very bad!
oil is normaly enterung induction systems from blowby.
try straight oil in your car, it works a treat.
checked manual for terrano, states sae30 ok down to 0 degrees.
i had to hand start a 60 year old diesel generator on christmas day in -10 degrees, started first wind over.
never been a fan of multigrade.

thats what I was worrying about, but with the amount of heat in there that would burn a lot of the oil leakage off, if I was getting a leak from that source I'd be seeing a big drop in oil level,which I'm not....we'll see when the weather improves a bit so I can get in there! LOL

 

[badger]

dont worry, i am sure you oil vapour is entering up stream from the turbo, but when it cools and forms liquid again, it drops down the pipe to the low point which is the turbo.
all diesel have a certain amount of blowby, but cool running ones on multigrade (there i go again about this) do tend to "breath".
you may find that at oil change time, no matter what the oil used, it is better for a day or two, also oil vapour out of oil filler cap when engine is cold will be zero or very little compared to at normal tempreture.
what sort of oil are you using? good brand or poor brand?
Synthetic or Mineral?
Synthetic multigrade is better at staying "non sheared" but is designed for new engines with no wear and smaller tollerances than engine of yesteryear.
try a straight oil next time, sae30, see how you get on in winter, remeber when we used to change oil grade for winter??

transit di's on bannana engine terrible at this the exhaust gases from egr hitting breather oil turns to sludge at bottom the intake manifold narrowing down the inlet ports sommat chronic.
