Buying a Turbo

[Lazy-Ferret]

So, after talking to Rick last night, I now know I really do know less than nothing about turbo's.

The other day, when having a tinker, I noticed a small bit of play in the turbo, which was the first time, but was not sure if it was ok... apparently, "No Play" in a turbo is OK.. Oppsss. Never knew that.

So.... where would be a good place to get a turbo from?

Do people re-furbish them? If so, an ideas who.?

I don't want/trust just any second hand one, but on the other hand, I don't want to pay silly money...

The only ones I can seem to find on Ebay are from the USA.

I have bitten the bullet and ordered a Recon unit. They send me a unit, with a full fitting kit, and when fitted, they send a courier to pick up the old one.

Had a good look around the web, but was getting silly prices on the model fitted to my car, not sure why, but it seems to be one that a lot of the places do not keep in stock.

A couple wanted me to remove it, send it to them, they would then fix it and return it... and for the pleasure of having my car off the road for a few days they were charging more...:doh

Just got to keep my fingers crossed now that I have made a wise choice... Not told the lovely lady I have just spent £330 yet either...:bow

Do some pictures when you fit it

I will try...

I have a Nikon DSLR, which I love, but do not like having it around with Dirty Hands, so I will try and remember to dig out the little Digital, and use that.

Was the play endfloat or up and down.If its up and down its normal.You said the intercooler had no oil in it so cant see how the turbo is at fault.

Yeah, but us men need our tools (toys):augie

Same, don't panic unduly. I've built Garret T25's and T28's, and a KKK VNT unit and like all of these Journal Bearing units, the up and down play will reduce significantly once oil pressure is applied to the CHRA and the bearings contained within.
If it is in and out play then it would signify that the thrust bearing is worn but if it's not passing oil in to the housings or just plain noisy then it will have some miles in it yet.

I'll probably rebuild mine next summer when I can take it off the road for a day but the harder job will be getting the turbo off than rebuilding it.
When I did the headgasket last September and took the whole head off complete with exhaust manifold and turbo I realised that there are bolts in the turbo and exhaust manifold that are VERY difficult to reach with them in situ.
Also be prepared for the possibility of bolts snapping in the turbo exhaust housing when you come to seperate the exhaust elbow from it. Just be aware of these issues before you start the job.

Agreed. Turbos have like 3mm side to side which disappears under oil pressure, its only the end float that could be a problem

Shame I'm late to this thread, 330 ouch
Never mind it'll be all shiny now :thumbs

Wow.. that thing was a git to fit... who ever designed that, really hated Nissan mechanics...

Luckily, I managed to get it off with out snapping any studs, but they did manage to send the wrong copper sealing washers, so had to walk round to the Motor Factors and get some of them. I also needed a 3/8th socket set, as the 1/2" set are too big to get onto one of the nuts, and there is not enough room around it to use a normal spanner.

I started at 10:30, the new one arrived at 12, and I finished at 6:00... would have been quicker, but my new High lift trolley jack decided to stop working after I had lifted the car up onto the stands to re-connect the exhaust. I could not get it back down, as even the T2's own jack does not lift that high... Sorted it in the end, so now I just have to wait and see if it is all OK.

I have never known something that not only did not have enough room for ratchet spanners or sockets, but needed so many things undoing, where you had to keep reversing the spanner, as there was not enough swing to turn it a full 1/6 of a turn, and get the spanner on the next flat. Plus the hidden bolts were a nightmare. Not only that, but the amount of times you end up dropping the spanner, and then have to get under the car to recover it.. if you are lucky, as half the time it got wedged somewhere you could not see.

Definitely not a job for the faint hearted.

Well done mate they are a bit of a challenge it's true.
Mine wasn't so bad as I've got rid of so much of the original truck :lol
Hope it solves your problem :thumbs

so have u stopped the oil burning and what was it, was it the turbo or valve seals

Hopefully...:thumb2

Changing the turbo made a massive difference, but as we had already bought the valve seals, I still wanted to do those as well.

There was so much oil inside the Air intake system, it needs a few runs to blow it all through, (When I stood the intercooler on it's end, about 1/2 a pint of oil flooded the drive way). It is too cold to go out there today to check it over, but I am quietly confident now that things are looking up. It got so bad that it was using 2 litres of oil in 60 miles, where as I have done over 200 now, and can't notice any missing oil.

Rick says the valve seals were not too bad, and I bow to his knowledge, but personally I though 1 or 2 were a bit "Hardened", when we looked at them, so am very glad we have done them now, as I can cross them off the list should I have any further issues.

For the first time since we have had the car, we were able to drive down the motorway with the sunroof tilted and not have a continual smell of burnt oil in the car, which is lovely, in fact, it was so good I forgot to shut it last night, but luckily I discovered that before the snow started.

Where I was trying out various things, coupled with the removal of turbos, intercoolers and feed pipes, all full of oil, there is so much oil plastered over the engine and running gear, that I am now leaving little drips of oil every time I park up, so I want to get that all cleaned off, just to make sure nothing is leaking.
So basically, I am waiting for the snow to go, then I will go out and have a good check round.

Happy for you mate

It's great when u finally get your pride and joy fixed

This comes way after this original post, but I find myself in a strange predicament concerning my turbo ... is it normal (surely it isn't) that there's always oil in the turbo, ... so much so, that I get some indications of it on the hoses entering and exiting the intercooler. I thought it was shot for sure after hearing that there should be no play in a turbo ... this thread offers some hope ... it only has about 1mm of sideways play - no end play The oil though, is still a concern ... is reconning a turbo, something a fairly hands on kinda guy could attempt to refurbish if needed ?

Thanks ...

From what I see, oil down in the turbo and intercooler is the norm on these... the problem is, how much???

The trick is to work out if it is coming from the turbo or breather system.

With hindsight, the trick is the disconnect the small pipe that runs from the breather system to the large air intake pipe, temporarily blank off the hole in the air pipe, and put the small pipe end into a jar to catch anything coming out. Clean out the turbo and intercooler, then take the car for a longish spin.

If there is oil in the Jar, but the Turbo is relatively clean, then it is the breather system, and you need to read the threads on here regarding catch tanks, and sorting the crankcase pressure relief valve.

If the Turbo is still full of oil, then you need to sort the turbo out, and pretty soon, as you do not want to experience "run away".

I looked at doing a refurb, but the cost, and amount of time I would have needed to have it off the road, it was easier to just source a replacement, and fit that.

The breather blow by valve often plays up & you end up getting oil drawn into the induction pipe before the turbo which is them forced through the rest of the induction side:doh what Lazy-Ferret has said is a great way to find out if the blow by valve is playing up, some have found after cleaning the blow by valve the problem has stopped I wasn't as lucky on my last T2 so fitted an oil catch tank & blocked up the hole in the induction pipe
