Oil In Intercooler Pipes / Out Of Dump Valve

[Ant 2]

Noticed that my 2.0 turbo is leaking oil out of the dump valve and theres a nice stream of the stuff in the IC pipes.

 

Obviously its not right. Any idea of what would cause this ?

 

Cheers

Sorry dude!

 

Sounds like the seals have gone on your turbo, BUT you do get a little bit thru anyway.

[sonofsam 5]

Yeah I think its quite normal to have a thin film layer of Oil inside boost pipes and IC.

 

Are you losing power? Any white smoke out the exhaust @ idle or start up?

 

All breathers plumbed in right and no blockages causing exccesive pressure pushing Oil past the seals.

 

Dont want to wish the worst on you Ant:(

Trace it to the oil breather, not usual to have the oil on the boost side of things, more blue smoke out the back :S

 

Give it a good clean out and try having the breather to atmos, other thing to check is the non-return valve on the breather isn't broken and you're ramming 1 bar in to the breathers lol

[sonofsam 5]

I take it the non return valve for the breather is that? ( highlighted )

like james says, vent your breathers to atmos or a catch tank, this is generally where oil on the boost side comes from.

 

when we took mine apart there was untold amounts of oil in the inlet pipeing from teh breathers. not good at all for power or economy.

Cheers Gents..

 

Power seems fine and theres no smoke

 

But it does nail fuel ( a lot )

 

Can someone explain where the breather is ?

I am hopint the fuel thing is a common trait, if not I have husg problems. I nailed 1/2 a tank in 45 mins. I will say though that the engine was pretty new to me and most that driving was done on full boost racing my mate in his mi16.

the 2.0l 8valve turbo engine has the worst fuel comsumption out of all the peugeot engines. I think the V6 can achieve more MPG!

I now think the little white plastic capsule up front of the filler tower is the non return valve:)

 

Yeah I use a fair bit of fuel, but not that much, have you all got your Lambda's wired in correctly?

Balls

 

Turbo ~ 20-23 MPG ( )

 

V6 ~ 19.2 mpg but is more economical on motorway journeys 36.2mpg. ...

 

..as far as googles concerned anyhow

 

Mine is a weekend toy so it doesn't concern me

All depends what box you run it on as to what fuel economy you get. Mine is incredible as the gauge hardly moves. Or is that just psychological because my other car is a V8!!!

I've had a Xantia 2.0 turbo with a manual gearbox and a 3.0 V6 with an auto box and the 2.0 turbo used noticeably more fuel.

the breathers are the two pipes circled here, one goes the the inlet piping and the other goes to [i think] the throttle body[?] either vent these to atmos or plumb them both into a catch tank.

 

just be sure to blank off the holes you leave in the inlet track securely or you'll get unfiltered air in the inlet hose and a boost leak at the throttle body.

Can you just block the breathers off rather than venting or will this cause adverse effects?

no if you block them you'll pressurise the sump and blow out all the oil seals!

Sam,

 

see where you have put the red line into the throttle body, well that go's from my throttle body to the boost controller! O.o

[sonofsam 5]

cRaZy, the picture is how my engine came to me, but you see the pipe opposite on the right, well that came with that pipe cut , as I had a pipe cut on my boost valve I assumed that they were linked.

 

There seems to be so many variations on a theme with this engine, recently saw one that didn't have that black plastic bellow as part of the Oil breather.

Sorry to hijack, but has anyone got the part number for the one way valve, as I need one for my TT, or can anyone recomend something similar?.

[sonofsam 5]

I had to get one recently for my brake servo line. An Aquatics shop is where I found one

Also known as a check valve @ Plumbers centre's.

Thanks for that Sam will give the local aquatic centre a go
