oooh, the mental picture :) u wont apply enough vac with yr lung.

 

thicker oil should help (spare the embarassment) in the meantime.

LOL - I should have saved it for valentines day really ;)

 

I've got a load of 5w40 oil at home so I was thinking I might put that in until I can get some 10w - if nothing else it'll act as engine flush and has to be better than the suspected 0w that is in now.

The baffle might do it, otherwise bung it up with some copper pan scrubs, if you can still find any round your way, and wire them in with some coat hanger wire. The UK turbos seem to smoke far earlier than J-Spec ones, and reducing back pressure shows any oil seal weakness up.

 

 

I'll have to try and remind the person who has my baffle to send it down then - the copper pan scrub thing sounds interesting but I can't say I've seen any for a long long time.

 

If you have the time can you explain exactly what is happening here (and that's to everyone not just Chris) - I don't understand why the problem is fairly random and why it only really seem to smoke when I'm stationary and even then not always.

 

Sometimes I just wish I was closer to a decent specialist so I could take the car in, pay my money and get the torture over with :)

always check the cheaper options first :)

 

michael, chris's isn't that far away, the journey's easier than taking yr chances.

 

i think its the higher backpressure in the exhaust helps the ageing seal do its job, there is a greater pressure difference between the oil in the bearing and the exhaust, so when it can oil will escape into the exhaust. thinner oil will escape more easily.

 

it happens more while stationary mainly because i can easily see the smoke and because the on throttle, off throttle driving produces the right condition for the oil to escape. this is stage1. it eventually becomes a big james bond style smoke screen :)

 

if the turbos r still in spec a reseal is alot cheaper than a full rebuild. the problem is u dont know if they r still in spec until they r off the car.

 

im still intrigued by the oily bov and oily air intake to no2?

So is £800 a good price for new turbos then?

 

(plus the usual shipping, taxes etc obviously)

I'm trying to do a crash course in hybrids and turbos now before my credit card gets full - am I right in thinking I have twin CT12B's to this spec:

 

Turbine Size 52/44mm

Compressor Size 58/39mm

Turbine material Steel

Scroll Scroll area (mm^2) 740

A/R ratio 0.53

 

Whereas the J-Spec is:

 

Turbine Size 60/48 mm

Compressor Size 62/39 mm

Turbine material Ceramic

Turbo Scroll area 600 (mm^2)

Turbo A/R ratio 0.42

 

 

I'll wear the search button out and then start a new thread if I need to - this one is dedicated to the memory of my oil seals :(

try to get your questions asked by jamie and its hard work. i asked him to build me a garret big single and not heard from him again. you can buy a nice single for cheaper than stock turbos, but you need all the other gubbings to go with it. have you looked on ebay for turbos, i am sure i seen a set of uk turbos with manifold on ebay other day. ibrar has a set too.

mate with a uk spec supra bought some sort of refurb kit for his turbo and he stripped and put back together think he said something like £100-£120

Yeah I've dealt with Jaime before - he was very responsive when I was talking about buying a T88 for an MR2 but with the Supra stuff he doesn't seem to want to get back to me... I'll keep pushing though :)

 

One option is to buy another set of UK turbos (Michel?, Ibrar etc) but it's a bit of an unknown quantity - they might be fine but then so were mine 500 miles ago :(

 

My mechanic chappy knows of a company in Lancaster that builds turbos for tractor pulling and more 'normal' applications - I'm going over for a flush and oil change on Saturday (10w30 Shell Semi Syth), a compression test and a really good look over things on the ramps - if the worst comes to the worst he has a car he can lend me and hopefully the car will come back with more power potential....

True but what I lack is time, I can't fix it while I'm at work from 8am > 6pm but I can ask questions, I can't fix it while I'm driving to and from work for an hour each day but I can look at the smoke :(

 

I don't have the equipment / know how / garage space to do anything with it at the weekends unfortunately so I've had to spend my time doing the little bits I could until someone I trust could have a proper look at things.

 

I've been on an information gathering session until now, tomorrow it goes to the garage with all this useful info in tow and with a bit of luck I'll be on the way to a (cheap) fix :)

i have to agree with nick and Chris and everyone else at the start of this thread.. its turbo seals.

 

In the initial stages of seal failure the smoke does seem random.. sometimes it'll do it, sometimes it wont. But whenever it does its always when sitting at traffic lights, after a run etc.. basically when the car is idling and has been run for a while.

 

The smoke is normally 'wispy' and hangs around the back of the car,as opposed to being blown out..

 

I was in denial for about two months when mine went, eventually i gave in and admitted it.. get them done now before the summer comes !

Yeah I'm kinda resigned to the fact you honest doom merchants were right, it was fun trying all the potential cheap fixes out in the meantime though, I've learnt a fair bit :)

I tried a few runs with no air con on and the smoke is more sporadic then, when the revs rise to run the AC it stops - with it turned on the horror is seem on most stops.

 

We went to Sheffield in it last night (Fun Lovin Criminals concert) and after a steady run on the motorway back to Leeds it was very noticable, very smelly and very embarassing - people in A reg Ford Escorts are looking at me funny now.

Yep that's the stuff.

This seems to have come along all of a sudden and despite me taking a long time with this thread I'm fairly happy that I'm acting reasonably quickly - the tricky bit now will be getting them fixed I guess but with a bit of luck my mechanic mate will be able to sort me out with all that soon.....

Just phone Turbo Technics agents and get an exchange pair ordered up! If the seals are gone the shafts will be buggered too. never known otherwise, on ANY turbo.

 

I'll have a look into this but I thought it might be a good time to consider a mild upgrade at the same time - I'm certainly not planning to go for a DIY oil seal only replacement anyway, I'll be getting the job done properly :)

 

`Tis only money ;)

 

Why does it hurt so much then? ;)

Sorry to hear it couldnt be fixed easily Mike..

 

I thought I might need new turbo's this week as I had loss of boost and all sorts. I changed the plugs though and found a leak in an intercooler pipe. All seems well now!

 

I'm glad to say mine was the easy fix!

 

Paul.

Shhh :)

 

It's a short term solution to prevent my blushes while I look into replacement standard turbos (awaiting a call back from Turbo Technics and email from MJM Turbos) and hybrids (not sure where to start on that one!).
