Hmmm something bad seems to have happened with the replacement engine I got fitted

 

There didn't appear to be any problem when I picked the car up.

 

The engine sounds OK and it seems to run OK however when I drove it back yesterday my friend who was following me said it was smoking a lot just from the near side exhaust but I didn't notice as the car felt like it was running fine

 

This seems to have gotten worse today when ticking over the nearside ehxaust is 'splutterring' a bit like there is an intermittent misfire on that side and when you rev it you get copious amounts of white smoke from that exhaust - and I mean plenty of it!!

 

I popped to the garage across the road and they had a look and revved it quite a bit and said they thought it was a turbo but could not explain the splutterring so then they said it could be 'just about anything' which wasn't very helpful

 

I parked up outside the house for 15 mins and then asked the missus to rev the car so i could put some video up here and now it seems to be smoking a lot from both exhausts like it just got worse in those 15 mins

 

The guy from next door came out (who also runs a garage) and claimed it is both turbos because if you compress the intercooler pipes with your fingers then rev the engine it should force the pipes back out again against your fingers. You do feel a little pressure 'kick' when holding the intercooler pipes compressed and revving but he says it is not enough

 

I'm not sure this guy knows what he is talking about or not but I must admit when you rev the engine the guage on the boost controller does not go positive it goes from -70 to about 0. I would have to run the car on the road and watch the guage to be certain

 

Any suggestions please, no doubt when I take the car the few miles to Trentham on Sunday (so it can sit there looking pretty even if it is turned off so it don't smoke) I will have 19 more opinions as to what is wrong with my car now :huh: so I may as well ask here first

 

I'll upload the video if I can remember my youtube login lol

I was informed by the chap that owns cr turbos that if the turbo isn't primed with oil "you will be lucky to get to the end of the road, before it fails"

Priming a turbo isn't very specific unfortunately. You simply get oil to circulate before allowing the engine to run, usually done without the fuel relay in to achieve this. I am sure this would have been done its school boy stuff.

What it sounds like is your turbo has insufficient oil supplied to it. This has caused the premature failure. A leaky or blocked line? An old oil pump that simply isn't providing sufficient circulation?

I do feel for you. Just so you know a failed seal won't kill a turbo it will just make it smoke.

Either the turbo's are not getting oil or there's crap in the oil for them to eat the bearings that quickly

Yeah will keep at it - so far I have three trashed turbos since this engine was changed in June, two catastrophic failures and I won't kniow what went wrong with the third one (the one silverline said had an oil leak) until it gets replaced

 

I'm not casting any stones in anyones direction here but along lines somewhere I don't feel this is my own fault - I had two good turbos on my old engine and two good ones (told be several peopl) on the new one

 

But what can I do? Thing is now I either dig deep and replace with new ones or I find another working stock nearside turbo second hand and I'll get Silverline to fit it if only on the basis of the fact that the one he did fit is still working

 

Anyone can help me out finding one, then it's very very much appreciated. Other than that guess I will have to bite the bullet one more time as I have no other option really

 

Rich

PS Jaffa, the oil has been changed. Maybe Steve will add a bit about the oil leak he found on the nearside one

I wouldn't fit another turbo till you figure out why they're being eaten up. Have the turbo oil lines been replaced?

Checking for play in a turbo shaft tells you a lot about the state of the bearings if you know what you're looking for. Fitting second hand parts is also something I have done a lot of on various cars, with the only main failure being the aforementioned T3.

 

IMO, there is zero point in fitting any more turbos without determining if oil is getting to the bearing or not.

So I have watched this thread go on and on without a comment from myself but enough now, there are lot of views from a lot of peeps that were not part of the original job. We only got involved with the salvaging and fitting of a used engine supplied by (another) to Richard, an engine that was presented in a terrible state, from how it had been removed to how ever it had been stored after removal.

 

 

 

So after the engine was cleaned of its hacked oil lines and wiring loom and much more it was serviced with new cambelt inlet hoses thermostat etc. water by pass egr removal and the new plenum installed and then fitted into the car.

 

New oil, antifreeze and new power steering fluid.

 

 

 

 

Fully run up and set up on the ConZult with smooth tickover and no faults, this was running for more than 30 minutes in front of Richard with no smoke no faults and the ConZult plugged in showing the set up this is how it was running.

 

The later issues that came to light with smoke was unclear and when the near side turbo failed it was changed free of charge ( supplied by Richard ) in order to help Richard we had no actual warranty responsibility as the engine was supplied by Richard to us so changing the turbo and the engine oil again was clearly a good will gesture on our part unfortunately however this thread has become now become a Zedworld witch hunt despite your veiled comments about not pointing at anyone..... you have had enough to say about us to others though! (all of it gets back to us)

 

We have been fitting engines into zeds for near on 14 years and for discussions calling us about how it was fitted or turbo`s are primed is verging on the ridiculous, your running on a budget that`s clear and and no issue with that but sometimes the cheaper option is not the best and for us a lesson in not fitting engines supplied by the customer!

When things go wrong there are no winners and the blame game begins. What this thread does show is that in future things will be done very different by car owners and garage owners. One good point as Jeff has said is buy your engine from the garage that will be doing the work then it can be bought with a warranty.

Keep at it Rich you are nearly there mate.

 

This is what I keep saying to new members buying zeds. Always buy the best possible 300zx you can with no faults and you will enjoy your car. But buy one needing work then it will cost a fortune and make your like a misery.

 

Plus unless you have deep pockets keep your engine standard or just a mild tune as this can lead to trouble also.

 

Just my thoughts and opinions after reading every thread on here for a lot of years now and having owned two mildly tuned zeds for over five years with zero issues.

The engine would have come from the exact same car regardless, as Richard would have bought the whole car if I hadn't had bought it first if I recall correctly.

 

All I know is that the engine & turbos were in very good condition with no smoke, rattles, sensor faults or otherwise. Removed on Sunday, delivered on Monday.

 

An engine that's been stood for months in anything but dry conditions needs to be pulled apart and checked at any rate.

 

Main thing now is to determine the reason for the failed turbochargers.

Just an Idea ...

 

the Sand that was discovered in the plenum and around the same time

Sticky rings .... its possible that the sand did make its way in to the Oil side

of the engine ... and there is still contaminants/trace of it

that may be damaging the bearings of the tubs ...

Just to be clear I never disputed any of the above Jeff (except never specified the length of car was ticking over ar Zedworld - no idea if it was 30 mins)

 

In fact I have posted these facts before on this thread (and the fact the car was not road tested) and also have been very clear that Zedworld changed the nearside turbo (the one that failed after 60 miles) Free Of Charge as a good will gesture

 

My main problem is I have gone through three turbos in as many months, two catastrophic failures and one I don't know the condition till it comes off the car

 

I've listened to advice and suggestions from Mark and Steve as to what went wrong and posted the advice as is (plus reading advice from on this thread). It seems something is pretty badly wrong, maybe with oil supply?

 

Yes it would have been best for me to get the turbos refurbed at the time the engine was swapped and yes I didn't do so as I didin't have the money at the time.

 

Everyone agrees, including me, that the engine itself is a good one

 

All I can do is ask advice and try to take it. I try my best to keep this factual, not a witch hunt and I'm suprised to see that posted

PS once again this is where the engine was stored before fitting (for about 3 months) - on this same trolley and with the doors shut of course. I also garage my car here over winter without the engine rusting

Edited September 25, 201312 yr by dicky96

Is that the same engine or the one removed from your car?

 

Edit: Never mind, it's a different engine.

Edited September 25, 201312 yr by Noz

Exactly - that is my old engine.... actually though I will pop up to the garage and take some more photos of it now, to see how it has faired these last few months in the same location and on the same trolley I stored the one you sold me for three months

There is quite obviously an oil supply issue, weather that's from a blockage or contamination Christ knows till it's taken apart. Until that happens no one can point fingers.

On a lighter note what wing mirrors are they dicky?

Had a chat with Silverlinie today - there isn't an oil supply problem to the turbos and the oil leak on the nearside turbo was on the oil supply pipe, but it was not enough of a leak to have caused the failure so I was told

 

Moving forwards, I've now got a price on a pair of GTX2860's if I am going to replace the turbos with new and upgrade at the same time then I will probably fit these as they come highly recommended for power vs spool time

 

I also will have a price in the morning from OD to refurbish one or two of my old turbos (or fit new cores) if possible, and then I can make a decision and get on with sorting this mess out as I don't think the smoking nearside turbo (my third turbo failure) is gonna last very much longer before something really bad happens to it

 

PS the wing mirrors are Ganador - bought off Zedworld second hand
