Found traces of oil in the x-over pipe and boost hose from Turbo 2 Filter. Fooked turbo?

Its done a grand total of 1.3k miles and about 99% of that on 10psi or lower

 

arent they ment to pass a little oil threw the pipes.

mines does it aswell so i hope so

 

Dan - chill!!!

Your always going to get this a little. Does ur breather go back to metering head?

 

Be worried when there is none

 

hes on efi rick,mines had death for ages dan no oil in mine wheres the turbo from ?

 

front seal then

 

Universal Turbos Tim

Rick - No Metering unit mate. And my breather is disconnected from the inlet.

I'll see how it goes on sunday to leicester, see how much oil is in there after 100 miles or so.

 

Lame..

 

Hope it's nothing serious mate!

 

As above !

 

1 word T TECHNICS

 

i had that and was told it was becuase i used to thin an oil

 

Hmm yes but I have a warrenty with Universal so cant really change now

Just spoke to them and they said its perfectly normal as there are no oil seals?? And unless its chucking stuff out the back / losing performance dont worry about it.

As its not and doesn't seem to be using much oil I'll leave it be for now. Keeping a close eye on it though. Fingers crossed heh

 

Come again???? NO oil seals???

 

Andy he is quite correct, some....not most turbo builders leave the front seal out and put a brass object in.....therefor no seal....it solely relys on pressure to keep the dribbles in....

heard this from a chap that used to work for 'the turbo shop'

how true it is i dont know????????????

 

hmm well i dont know enough about turbos to question it. Suck it and see i guess........

 

Ive read articles in magazines years ago about turbos, and from what i understood even the lowest spec turbos had a basic oil seal, and i thought that was the whole pressure principle, being the gap in the seal was so tiny there wasn't enough pressure for oil to pass.

Even a standard T3 has an oil seal......

 

ive been looking on the tinterweb at techy diagrams of the T3 ....oil seal present .....

so whoever told him that there wasnt one...they was lying

 

Can someone with knowledge of turbos ring Universal and quiz them on this for me??

 

I thought so, already they sound like a bunch of cowboys

all you wana do is ring them and say why does my turbo not have an oil seal if a standard OE (original equipment) T3 does?

 

Right....

Spoke to Universal again and a very helpful chap spent 5 mins explaining this to me.

Basicly its a type of piston ring used, as oil seals cannot withstand the tempreture inside a turbo (makes sence to me!)

The vacume around the turbo determines how well these seal the oil inside. Large exhausts (low back pressure) can cause the turbos to spill oil out of the compressor housing
but this is the norm and traces of oil in boost pipes is acceptible.

Final words where.... worry if its puffing oil out the back. Which it is not!

Any comments people?

Dan

 

Yeah, the piston ring is the oil seal (as they are in engines) so i duno why they are trying to be clever about it.

I dont see how their explanation of low exhaust pressure can cause the compressor housing housing to spill oil???? (unless you mean the exhaust side spilling oil which makes sense)

Annoying when the different people on the end of the phone tell you something different everytime isnt it

 

Yeah it is. Although to be fair i was probably saying the wrong words

End of the day they said its perfectly normal to have traces of oil in the boost pipes just watch out for anything out the exhaust.

I've just been looking at a boost pipe i had sent off to have a copy made (another story) and its clean as a whistle so might be worrying about nothing anyway

Cheers for the advice though!

 

Its not un-common to get oil in pipes as long as when you take the pipe off you dont need something to catch it in, if you catch my drift......

There are people that don't get any oil in there pipes (never me i might add )

Go on.......share this other story You've started so you may aswell finish

 

lol ok.........

I had a boost pipe made up to move my air filter out of the way of my oil cooler duct (see resto thread ) but it silenced all chatter from the turbo. Not having that, so i've moved the oil cooler and just having a new boost pipe made so the filter comes off the turbo as straight as possible..... so more chatter

Hence me finding all this oil in boost pipes

 

Ahhhhhhhhh, so presumably the other pipe had a bend in it

And it killed your chatter
