oil leak arround turbo.

[infinite]

Ok have finaly got my exhaust linked up but when i got home i noticed im spraying oil all over the brake booster/clutch master cylander and all over the ds axel/side of gearbox! oils evan sitting ontop of the turbo... Its a td04 turbo would this posible be the oil return? its definitly not the feed line and i cant see were else it would be coming from only happens when under boost. is a bf5 legacy wagon

[infinite]

Ok i took the turbo off today and it was leaking between the oil return fitting that bolts onto the turbo... ive replaced this and got the surfaces smooth and put a genuine gasket back in!. the only problem is its still leaking from some were i dont know were tho? there is oil sprayed all over the place and i have no idea were its coming from? whats the chances i need new banjo bolt washers on the oil feed? im planing on geting them tomorrow wen i get paid anyways but anyone got anymore ideas?

Get the car warm, the have a look under the bonnet while its running at around 4-5k rpm. Should be enough oil pressure then to squirt the oil out if there's a minute crack somewhere that leaks under pressure.

ok il try reving it up... heres some pics

Looks like the Exxon Valdez crashed into your engine bay....how much oil does that thing go through?

long shot but is your dip stick for your gear box all the way down fully?

[infinite]

yeah its alot of oil other than that the motor dont actuley leak oil! have just replaced the banjo washers and theres still oil comen out!!!!!!!!!! i got no fucking idea were from!.

What i have noticed is the pipe from turbo to bottem of inter cooler isnt sealing corectly and once u just in the revs 4.5k it starts letting air out and is blowing the oil towards the turbo! and i know there is a bit of oil in the intercooler as the last turbo blew the seals... so im starting to wonder if whats now coming out as the oil has got less now the bottem return is fixed and the banjo washers for the oil in line have been replaced so going to remove the ic again and fill with petrol to try and flush it again have done it befor not with petrol tho... Also could the seal arround were the turbo housing goes onto the cast part on the td04 have a blown seal there? If i pressure the turbo's oil lines by blocking one and blowing in the other should it pressure up? as when i did that it was definitly letting presure out some were.

i wonderd that... but it just wont go down anymore! but looking up from under the car u can see that the inside of the cap isnt touching the top of the tube. it sorta just sits over it covering it... is this correct or somen wrong wid the dip stick

[Guest]

Are you SURE the oil feed isn't split, as they are quite fragile and ya gota bend it outa the way when removing the turbo and this can happen then. There is a LOT of oil there and looks like its squirting out under pressure by how far it has gone

[log1call]

Let it cool down then wash it with a bit of petrol followed by a good hosing with water. Then start the motor and run it for about thirty seconds and turn it off and see if you can see where it's coming from. If it isn't leaking after thirty seconds leave it idling and have a good look for leaks, then if you haven't found it rev it a little while you watch, if that still doesn't show what it is go for a SHORT drive, like two minutes worth then pop the bonnet and have a look. Use a light and mirror to look underneath as well.

ive been degreasing the engine bay befor every test run and by time im 20 mtrs up the road its everywere im at a loss as to were its coming from.. wonder if the oil line is broken... its had a fair bit of pushing round turbo's been off 3 times now!... but to be honest the line is prity damn clean and the spray pattern is in the wrong place for it? but then again when your driving it would be falling back onto the firewall.... well ill take the oil line off tomorrow after i have a last test run as ive run out of everything to clean the current load of oil off

[NotAWhiteGTB]

If you want to test if it is going back onto the firewall due to wind you could always jack the car up so all four wheels are off the ground (on axle stands) and then drive the car on the axle stands and put your left foot on the brake to load up the motor and produce boost. that way it will only squirt out in the direction from where it is leaking.

if i dont get it fixed quick smart tomorrow ill be doing that...

[infinite]

After the last test run it hasnt put asmuch oil out but its still smoking from arround there and oils still building up just not going right back to firewall so ive gota give it a realy good degrease tomorrow then ill take it for a drive and check it over a couple of times while im driving it. ive also put the stock bov back on as the one the car come with is leaking pressure. pos

There was oil in the bend that goes down into the turbo not much but all the pipes are a bit oily as the last motor that the pipes were attached to had stuffed oil seals in the turbo. and the ic has a bit of oil in it still witch im going to clean tomorrow!. the turbo looked prity damn good. boosts very well. nothing has been modifyed just put a new engine into the shell.. the oil is at right level

[Guest]

The intake pipes will always have a bit of oil in it due to blow back from the breathers, you can normaly see it pooling in the IC joins etc.

is there any oil inside the downpipe?

nope was nice and clean except for some soot as to be expected lol, oil seems to be 99% gone now!!! so think i finaly got it just needs a damn good clean but took it for a 20min run and its burnt what was on the exhaust off and its fairly clean now!

[RSB]

Cant see the pic, but if you didnt replace the copper crush washers on the oil feed line my moneys on that.

When i swapped out my turbos, i didnt replace the washers and while oil wasn't spraying over the engine, after boosting smoke would POUR out of the bonnet like the car was on fire.

Replacing crush washers completely solved it.

Edit: I see now you've done that lol.

[matariki_gt]

is it still spraying oil now the standard bov is on? the samething happend to me, turned out to be piston oilseals
