Kaan W Posted January 8, 2013 Share Posted January 8, 2013 (edited) Hi guys, I was just out and about on a casual drive with the occasional blip here and there to find when I got home there was smoke coming from under the bonnet. So I lifted it up to inspect and after the smoke cleared ive found oil leaking from the turbo return line dripping onto the exhaust manifold Not only that but water seeping out the aeroquip fitting from the water return line also. The water leak has been like it for a while and I needed to change it as the hose is pulled quite tightly accross making the connection a bit weak. What I would like to know is why the braided hose for the oil return has no fitting on the end of it and seems to be jubilee clipped over a flared pipe that runs into the turbo. This is where the oil is seeping out of, I could try and tighten it more but why has the turbo not got a threaded hole for a proper fitting? Also I dont know how hot oil should get but it looked like it was bubbling out from the hose but I dont know if thats just down to air seeping past. Thanks in advance!

We've had issues with you not knowing the difference before! hope you get it sorted mate and its no big issue What! It was me that corrected everyone else on the difference in steam and smoke Its definately smoke from the oil side and steam from the water side Im just wondering if the turbo has a thread on the oil return so I can use a proper fitting or are some built with just a flared pipe to jubilee a hose over? Its driving me mad ive got my mapping session in less than 2 weeks so need it sorted Quote Link to comment Share on other sites More sharing options...
Kaan W Posted January 8, 2013 Author Share Posted January 8, 2013 Just nip up the oil return, should stop it What does that mean? I can prehaps put a new bit of hose on and retighten but I doubt it will hold if its under that much pressure. Quote Link to comment Share on other sites More sharing options...
Kaan W Posted January 8, 2013 Author Share Posted January 8, 2013 This is what it has now - http://shopping.kinugawaturbo.com/turbooildrainreturnpipekitgarrettt2t25t28tb02-1-1-1.aspx Shall I just replace it with something like this? - http://www.ebay.com/itm/17-10AN-TURBO-BRAIDED-OIL-DRAIN-RETURN-LINE-Garrett-T3-T4-T04E-T70-T60-T61-GT35-/180780614223 Quote Link to comment Share on other sites More sharing options...
Chris Bailey Posted January 8, 2013 Share Posted January 8, 2013 Replace it with something like the second one on Ebay - Most people seem to run them feeds. Looks much better quality than the first one you posted! Quote Link to comment Share on other sites More sharing options...

Looks much better quality than the first one you posted! Its just getting hold of one and fitting it before it goes to Ryan. I dont know why it was bodged up like this in the first place when all the other feeds and returns have the correct fittings. Quote Link to comment Share on other sites More sharing options...

Dads car is going into Whifbitz on the 17th for Injectors and coilpacks and a new fuel pump and Ryan is mapping it again on the 24th Quote Link to comment Share on other sites More sharing options...

I'll have a word with Paul see if he has one laying around. Does anyone know the best way to swap these oil return flanges over is the system under pressure or does it require draining all the oil out the engine?

black_widow87 Posted January 8, 2013 Share Posted January 8, 2013 Oil drain should not be under pressure, how ever i would make sure the car has been standing so engine/oil is cool. Quote Link to comment Share on other sites More sharing options...

Ok thanks, so it should be able to be replaced without draining anything? Quote Link to comment Share on other sites More sharing options...
black_widow87 Posted January 8, 2013 Share Posted January 8, 2013 Yes the turbo will drain itself. Just make sure the manifold is cold, last thing you want is to catch your hand on it like i did.lol Quote Link to comment Share on other sites More sharing options...

It will be cold as im not using it until its fixed the last thing I want is for it to come off completely and probably causing a fire.

mellonman Posted January 9, 2013 Share Posted January 9, 2013 whifbitz do all the parts for the oil return and you can easy make one up in 2 weeks mate , for the water line just get some new pipe from any motor factors, if not im sure http://stores.ebay.co.uk/Torques-U-K will have everything you will need at a great price with quallity gear Quote Link to comment Share on other sites More sharing options...

Im not sure I can fit this myself ive just been trying to get to it for the past few hours but its so tight to get to I cant even slide the heat sleeve down to undo the jubilee clip.

Kaan W Posted January 9, 2013 Author Share Posted January 9, 2013 Ive just tightened the jubilee clip up as much as possible just until I get the proper return line kit, would I still be able to drive the car until this arrives? Does this part of the oil system get alot of pressure or is it just for the oil to trickle back down into the engine? Also should I heat sleeve the braided hose? I thought aeroquip hose was fire and heat resistant Quote Link to comment Share on other sites More sharing options...
Hellstrom Posted January 9, 2013 Share Posted January 9, 2013 (edited) I would fix that before driving any futher. If you think your fix is enough then carry on. Leaking oil around the turbo is never a good thing. There is no preasure in the line. If your line is too small diameter it may not be enought to evacuate the oil in the same pase it goes in to the turbo. I would not use a heat sleve until you are 100% sure you have fixed the leak as i may soak the sleve in oil. Yes it is probebly heat resistant. But you dont want to boil the oil too much on its way down as that may clog the line with burnt oil. Heat sleve is a good thing in my opinion Edited January 9, 2013 by Hellstrom (see edit history) Quote Link to comment Share on other sites More sharing options...

I thought aeroquip hose was fire and heat resistant There's not much pressure there no, more of a trickle. Thermo sleeving the braided hose is a good idea, if its close to any heat source that is. Braided hose isn't fire resistant no, you have a ptfe/rubber hose inside which can melt. Quote Link to comment Share on other sites More sharing options...

Ok thanks Paul, just uploading some pics to get a better picture as im really not sure if the adaptor will fit or not Quote Link to comment Share on other sites More sharing options...
Kaan W Posted January 9, 2013 Author Share Posted January 9, 2013 So here is the turbo end, will the adaptor and fitting clear the exhaust manifold? And the engine side of the line, it looks like I will need a 90degree fitting to bring the hose straight up? Quote Link to comment Share on other sites More sharing options...
Guigsy Posted January 9, 2013 Share Posted January 9, 2013 That seems in a very tight place. Iv got one of Paul's kits to install as mine is leaky too but my oil return is underneath and seems much more accessable and only dribbles very slowly down onto the front subframe Quote Link to comment Share on other sites More sharing options...
