Can anyone advise me where to get a turbo repair kit, for a good price on the internet?

what has happened to the turbo?

And there is more to just repairing it, youll need to get it balanced ect when you have changed any new parts.

Well there's white smoke coming out the exhaust on the left hand side when the car is warming up and the mechanic told me it was a turbo going bad (u think this is true?)

anyway he hasn't got a turbo repair kit so he told me to get one!!!

oh yeah by the way I have a 94' TT manual 2+0

well its an engine out job really to get it sorted.

You can do it with engine in but i think it is easier to pull the motor.

Also a good excuse to get things checked out in the background.

Sounds like turbo, but could be some other things.

Do you know any sites where I can get a turbo repair kit from?

 

No one i could recommend really but try

Jim wolf tech, i think they are a very safe bet for replacment turbos ect.

 

Where are you in the world?

Do you know North Cyprus?

The divided country. I live on the north side(turkish side). Not many zx's in our country, we have 3 tt's including mine and one N/A, so no one really knows about the Z engine and how to maintain it, I'm having a really hard time looking after it but I can say I have the best Z in my country!

You can replace the oils seals on the turbo relatively easily. though you need to be aware that the one of the nuts holding the impellas on is usually a left hand thread, and snaps the shaft easily.

 

However the seals do not go for no reason!! they usually go because the bearings are worn allowing excess shaft movement. The bearings usually go because of lack of lubrication. Lack of lubrication is usually because the oil feed within the turbo is blocked (usually burnt oil residue from insuffucient cool down time after on boost running. (Your exhaust gas is at about 700 degrees culcius - the turbo temperature is controlled by water and oil passing through them - if you switch off and stop the flow it just boils away..)

 

You will certainly upset the balence of the turbo by dismantling it and reassembling it. Out of balence will also result in rapid failure of the bearings / seals. Very rapid, given that you can expect speeds in excess of 100,000rpm with these little turbos / high boost.

 

If you don't mind some advice - Take the offending unit off and ship it to a specialist turbo overhauler for reconditioning. they will do the same job as your mechanic, except that they will replace the impeller nut(s) and balence it. Unless the unit has been abused to death I've never had to spend more than £300 for this even on some very rare motors.

 

I've got a contact in my book at the office in Essex / England who will work mail order if you need it. Just reply here and I'll sort it out for you...

 

Bon Chance.

Oh. You may also want to clean / replace the oil feed and return pipes when you put it back on!!

Cheers mate,

The thing is I've got money problems and my mechanic told me he would do it for £150

(not bad), but the question is can he do it properly. I don't really care about the money when my Z is involved but when I haven't got any thats a differn't problem!

Is it really hard to balance the turbos, because the mechanics in my country are useless. If I asked him if he could balance the turbos he would say yes but how could I understand if he could or not? is there a way to understand? pls help me cause I don't know abut balancing turbos!

Thanx in advance

unless hes got (very) specialist equipment, then no, he wont be able to balance it

I feel the need, the need for speed!

If your turbo's don't make strange noises don't leak oil (when it's leaking inside the smoke color is blue)and can build up enough pressure I won't bother if I was you.

Don't fix things that aren't broke, it improves nothing but only costs money.

 

The car does none of the things you said, but how am I going to fix the problem that I have got at the moment. Which is white smoke coming out the exhaust ( more out the one on the left hand side) when the car is warming up?

If your exhaust smoke is white it IS water and if you don't have to fill up your cooling liquid regulary then it can't be something else but condensation. Should you be colorblind and the color would be blue then you have to fill up your oil level very often which isn't the case.

I don't think that you realy have a problem.

Other cars do also have some white smoke coming out of their exhaust when warming up, some cars more than others.

You could try www.turbotechnics.com

They`ve got a handy section on there

website.Quite infomative.

I'd back up the advice to send the turbos off - the cost of repair is likely to be less than the cost of removal and refitting of the turbos. Or is this included in the £150.

 

If so then check that your mechanic really knows what he's taking on.

 

It's such a big job that it's not worth trying to save a little. If it isn't done right then it could be very expensive to put right.

 

However, it doesn't sound like turbos from your description. Do you do mainly short journeys ? If so then it could be condensation in the exhausts. Not sure on your climate but if there is a big difference in temperature from day to night then condensation is likely.

 

To test turbos, get the car up to operating temperature (drive for 20 minutes) but don't drive it hard. Then stop the engine for 5 minutes. Then restart the car and let it tick over. If the seals are knackered then you'll get a lot of blue smoke within 2 - 5 minutes.

OK just seen this sorry dude.

 

Do the Test that Hairsy recommends - its a sure fire winner on catching blow turbo seals.

 

If that passes and you dont have any problems with boost (i.e Power feels good and you get a reasonable reading on the boost guage (9 - 14psi) And you dont hear loud whistles of screaching under boost chances are the turbos are in reasonable condition.

 

If you are gettin heavy white smoke it could be one of two things.

 

1) Exhaust / Cats are blowing (cracked) and are lettin excess water into the system - I had this problem on my car as the Cats were leaking now they are replaced it is fine.

 

2) Head Gaskett has blown on the cylinder bank that is smoking - if it smells like coolant then this is your problem - Do a compression test - It is easy to do and only needs a 20$ peice of equipment - If you have low compression on 2 cylinders that are next to each other on the same bank then you have head gaskett failure - You will need to Pull Plenum + Cylinder head and replace - A fairly time consuming job and again not one for a monkey.

 

hope you find the problem and get it sorted.

God is coming ...and he dont have stock turbos . . .

Here are some pics to give you an idea!!!

After 1 minute:

 

After about 3 min's:

 

Fully warmed:

 

Looks worst in real life!!!

These were took 9/6/2002 12:00am

More Problems!!! sorry the date was wrong in my last post it should have been 7/6/02 and if the pic's are not working go into properties and copy paste the url into your browser, it should work like this

Thanx

 

Anyway the problems just got worese and I@'m really worried!

It's all my fault cause I didn't I haven't been checking everything!

yesterday when I was coming home from work

I drove the car a bit hard, I drove for about 25 miles and came home. I left the car on to cool the turbos down after about 2-3 minutes I heard a sound from the engine, I opened the trunk and there was a coolant smell and then it started to blow out steam like a pressure cooker! I went to turn the car of and noticed the heat was at H with the fan working! I turned the car off and 3 hours later checked the radiator for water, it was empty!!! And the smoke has got worse!

 

What the hell is going on???

Please help I couldn't sleep last night and it looks like I won't sleep until I sort this problem out!

Thank you in advance

Sounds like the head gasket to me. No offense though, if your mechanic cannot diagnose this - don't let him open the bonnet. You can spend an awful lot on a z32 by misdiagnosis.

 

From what you've said though the headgaskets blown from one of the pistons to the water jacket. There are lots of tell tales - one of which will be a clean piston, but you have to take the head off to find it. does the engine hydraulic on start up? (I.e. if the bore fills up with coolent the starter struggles to 'squish' it out - engine does not turn / turns very slowly on crank). If you continue to drive it, it will get easier to diagnose. However if it overheats you will probably do a LOT of damage (warped heads / blown gaskets etc.).

 

Bad luck. This sounds like an expensive repair, whatever it is. I would also emphasise that a good mechanic should be able to diagnose this and errors are expensive...

Time to park that car until you can get it sorted, your just going to start doing engine damage now.

This could end up in big tears for you.

Where does the water in the radiator go???

And how much do you think the repairs will cost (just the parts)?

And can you explain me what my problem could be as my knoweledge is limited about the z engine!!!

The coolant gets sucked into the combustion chamber and gets 'burnt'. This explains white 'smoke' (steam?).

 

Cost of parts is just gaskets at the moment, and obviously labour to strip and rebuild manifolds/head.

 

Coolant gets into the combustion chamber through a defective cylinder head gasket. This needs replacing.

I only use the brakes so I can accelerate all over again.

I fill the radiator with normal water is that alright, what should I top the coolant up with?

I fill the radiator with normal water is that alright, what should I top the coolant up with? How much would gaskets cost in england? (just wan't to compare?)

Sorry mate, does sound like a blown head gasket.

 

couple of other ways of checking:

 

fill the rad back up with coolant & start the engine, let it run with the cap off & check for bubbles in the coolant (gasses from the combustion chamber being forced past the h/g into the water jacket) if its really bad it will just dump all the water out of the rad, esp when revving the engine.

ps this may also happen if there is an air lock in the cooling system.

 

get a testing kit from most good motor factors. this is a liquid that you put in a "test tube", place the tube in the top of the rad and do the above test. the liquid changes colour when combustion gasses pass through it, indicating head gasket failure.

 

when the heads are off, check for distortion & get a machine shop to resurface if needed. there is a limit to the amount that can be skimmed off but I am unsure of the limit for these cars, im sure someone here must know

 

hope this helps.
