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

Keith and myself told you a good blast would burn the shite out Rich..2nd course of action should be to get that now knacked cat off and get your AFR checked out as that motor is running stupidly rich....

Just keep your fingers crossed, it sounds promising.

This car is totally insane!

 

Or makes me sound like I am by describing the latest situation

 

OK yesterday I gave the car a good blast up to Ians BBQ and back (round trip about 100 miles) especially on the way back when the car was driven harder than it has been since the engine was changed

 

Anyway she was smoking quite a lot on the way back when accelerating but not much smoke at all while cruising

 

The only notable incident was when reaching the A500 in stoke and flooring her in 2nd then 3rd all of a sudden she lost a lot of power while on full boost, backfiring etc.. Turned out she was suddenly only running on 5 cylinders. After a few miles we pulled over and all that was the problem this time is one of the coil pack connectors (front cylinder off side) had come loose. Pushing that down she was back on all 6 again. The last few miles we gave her plenty more boost and the smoke was there as before.

This morning I decided to check the oil again and was a bit shoked to find it was only just registering on the bottom tip of the dipstick. About 1 litre of oil saw it topped up to near on max. Surely this must mean she is buring oil and not just smoking because of residues in the cats?

 

Anyway I had to nip down to Tescos so I fired her up......... and thought 'that's funny, where's the huge clouds of white smoke?' Because there wasn't any. I mean like none! Tescos is only a couple miles away and I gave her a bit of a boost and no smoke. Once i came back she was up to temp so I gave her a good boost. No smoke.

 

Puzzled to see if I am just imagining this, after lunch (about an hour but the engine is still warm) I checked the oil again - nearly full. I fired her up and free revved her - absolutely no smoke. I mean even like there doesn't really seem to be anything at all coming from the exhausts

 

So what's this all about. Am I going mad? DId I have too much to drink last night? Have I imagined the whole month of problems? Will the smoke be back again tomorrow?

 

Please for my own sanity - is there an answer to these and other questions?!!????

 

dicky

Oh and PS if anyone can answer that lot, then why is it only 15deg and grey with light rain today as I type when the forcast says the heat continues?....

keep and eye on your oil .. Using around 1lt of oil in 100miles or so is quit alot ... and would suggest that its going some place

There you go buddy, Keith and Brian have laid their healing hands on your car for you.....pmsl. Pitty they both can't do the same with the weather, but they are only Zed God's after all.....lmao

keep and eye on your oil .. Using around 1lt of oil in 100miles or so is quit alot ... and would suggest that its going some place

 

 

Agreed though it is also somewhat an improvement on 1litre in 12 miles, with that blown turbo!!

 

I fired her up again, no clouds of white, and just the normal sort of exhaust gasses you would expect on free revving really

 

So now I am worndering, seeing as the smoke has stopped is the oil use also gonna stop. Guess I need to take her out for another run. Where do I get my AFR checked?

 

As no one replied yet, are the decats I found on ebay £129 any good? http://www.ebay.co.uk/itm/NISSAN-300ZX-Z32-TURBO-NON-TURBO-STAINLESS-STEEL-DE-CAT-DECAT-DOWNPIPE-EXHAUST-/230713275628?pt=UK_CarsParts_Vehicles_CarParts_SM&fits=Model%3A300+ZX&hash=item35b79534ec

 

Actually this car is chipped (don't know what chip as it was done before i bought it) and has HKS Boost controller. Assuming this was all set up correctly before, then it was set up for my old engine. Would that make a difference?

I'm looking at getting those decats aswel so be good to know if they are any good. Hopefully things are looking better for you mate.

I am pretty sure they are the same ones I fitted on my old blue Z as the old ones failed, but the car was written off a week later so couldnt' say much apart from they did fit.

A few people have those, 2fast2cool is the same parts as japspeed. Those ones are good as they don't remove as much back pressure retaining two silencers per side. The ones I have delete everything but the back boxes. You also won't have to unbolt the turbo elbow, which can be problematic, yours should be easy though as they've been off twice recently.

Downside is you will gain less by not having divorced downpipes and possibly retaining a precat.

I think thee a sensible buy though in the real world.

 

As for the afr, a local rolling road would be best. Someone like Noel, or indeed Noel himself. You need to make sure those boost leaks are resolved aswel mate.

Tom (mogsy) they will fit yours...Richard as long as you have the pre-series 2 elbo,s on your tubs they will fit yours. They wont fit the late 93 onwards with the pre-cat in the elbos.Ask jeff or mark which type you have.

Rich, I have just purchased these decats: - http://www.ebay.co.uk/itm/310374431707?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

 

I don't know what they are like, or what they are like to fit, but I offered £150.00 and it was accepted.

Them ones are the divorced type for a turbo fitment Ian...4 bolt on turbo to replace the elbo.Yours being an NA will need the 3 hole type the same as what Dicky has listed mate.

You're kidding, they said that these will fit a TT or NA!!! So they are no good to me then Bri?

My Z is a bit of an odd one I think, in as much as it is a 93 but has the seatbelts fitted to the doors and does not have keyless lock/unluck Don't know about the turbo elbows but there are some pics on this thread here http://www.300zx.co.uk/forums/showthread.php?170333-Lots-of-white-smoke-when-revving-engine&p=1740662&viewfull=1#post1740662

Is it a uk car? Or import dicky.

Import

Time to resurrect this again

 

OK if you all read the thread then you all know the history. However I am not totally out of the woods yet I don't think

 

I've done a few hundred more miles - in fact I took the car out for a 230 mile round trip today

 

The car is generally not smoking on startup or running / cruising however if I give it some boost I get a big puff of smoke when I change gear. If I change up after gentle acceleration I don't get the smoke (or anything noticable while looking in the rear mirror)

 

Generally speaking the harder I am boosting the car the larger the smoke cloud on gear change

 

It last for approx 1 second when changing up and then clears again

 

The car does not seem to be using appreciable amounts of oil (haven't had to top her up since the big smoke problem automagically fixed itself)

 

Do these symptoms point in some specific direction

 

cheers

Rich

Has the car been mapped?

Not yet but it is 'chipped' but that was before the engine was swapped andit also has a HKS boost controller

 

I'm waiting for Noel to get back to me about mapping the car

 

Rich

It's over fuelling surely, get Noz to remap it

Rich your car is over fueling on a massive scale mate..i bet the rear bumper is black above the pipes.You need to get the AFR checked right through the rev range as ime thinking 1 or more of your injectors are goosed.

My Z is a bit of an odd one I think, in as much as it is a 93 but has the seatbelts fitted to the doors and does not have keyless lock/unluck Don't know about the turbo elbows but there are some pics on this thread here http://www.300zx.co.uk/forums/showthread.php?170333-Lots-of-white-smoke-when-revving-engine&p=1740662&viewfull=1#post1740662

 

Any engine bay shots?

My Z is a bit of an odd one I think, in as much as it is a 93 but has the seatbelts fitted to the doors

 

That is normal, 'proper' mounts were 94 onwards.

Mine did exactly what you describe with the smoke and what Brian says above, but since Noel mapped it the issues have gone :wink:.

That's incorrect, the series 2's started late '92. Dicky, have you checked the date on the seat belt labels?

Really, I was going off this I read moons ago on Wikipedia, haha.

 

I wonder Rich if you have a Series 3.
