I have searched thru the forums and looked for posts that have similar problems to mine but cant find any that are just like mine so here it is....

I have a R32 with a R33 turbo and noticed one night driving home (from a cruise,and 1 small burnout from the misses) that it was spiking from my set boost of 13.5 to 15psi.I dont check my boost gauge everyday but close enuf to it so cant say how long for sure it had been running at 15psi.When i got home i let the car cool down for 2-3 minutes then turned her off.The next day when i started the car up it was warming up for 3-4 minutes then as i was reversing down the driveway i noticed a thin cloud of white smoke in the rearview so i got out and checked and coming out from the zorst was a thin stream of white smoke.I didnt think to much of it at the time and thought hopefully that seen as it was a very cold night the car was just a tad cold still so i put it down to that but as i took off up the street there was a small white cloud following me still.It stoped blowing in the next street but still the thought had me worried of a blown turbo or even worse it was the the rings or the engine was on the way out.I had a mate follow me the other day seeing if it was blowing any smoke and he said it wasnt really xcept for when i stopped at lights idleing and then on take off.The engine seems the same to me,revs the same,sounds the same and is making boost as about the same as b4 the smoke started but still the smoke is there.I went to the shops today and as i pulled in and clutched it in2 a parking bay and a mass of white smoke whaffled by me,i turned the car off and when i came back and started it up and idled there was no smoke at all even as i took of and on the drive home there was no smoke at all.I asked around and went to a workshop today but the drive there and in the workshop car park it didnt blow any smoke so the guy said until he sees the smoke colour and smell himself he cant really say for sure what it is..

I have had silvias an 180sx's b4 and have blown a turbo in them but it was like boooooost then BANG no power black smoke and so on but this has got me stumped as to what it could be.I have looked all arvo for leaks or any problems but cant see any exept for my catch can has a bit of oil on it.

I will be taking it to a workshop to have a inspection in 2 weeks but any help or feedback would be muchly appreciated in the meantime thanks.

thanks for the reply (Bubba and Mr Keets)...(i could be wrong) but I dont really think it is the valve stem seals as i cant see any smoke on deceleration only on take off and idle.Nah i dont thrash the car and that small burnout that night was the first and last and its not the misses fault,she actually is a good driver and WOULD put some of the guys on this forum to SHAME :( ..I warmed the car up today (but am to afraid to drive it incase i f**k it even more) but just sat there idleing an saw no smoke.. Question: if it is the turbo on the way out shouldnt it smoke all the time not just on idle and take off???...

condensation perhaps? Every car blows white "smoke" when you first start it up around this time of year when the engine is dead cold. and it stops once the engines come to opperating temperature. until you can rule this out then i wouldnt go jumping to conclusions. my advice is to take a step back and look at the situatuation and the symptoms then work out from there a list of repairs that can be made going from cheapest to most expencive and start at the basics. but yeah, as i said it could just be the condensation from your exhaust heating up and turning the water to steam.

Scott...check your rad, low and or oil?

Checked oil,its fine and doesnt seem to be using any more then normal and no discolour/sludge in engine as i took the cap off and its just oil in there.

Checked radiator for oil and there wasnt any signs of oil,its the normal light green colour.

Checked the lines to and from the catch tank (thought i'd rule shit out) and all looked normal.

Took a section of the front mount piping off and no signs of oil in there either.

Ive been looking this morning at some posts on here talking about the pcv and smoking issues but dont know where xactly it is on the engine to take a look myself.Does any1 know bowt the pcv and if they or a friend has had problems with it b4 as im freaking out that it might be the engine dying not a $50 to maybe a new turbo job im looking at...

compression test see if you have even pressure across all 6 cylinders within 10 percent of each other if not its most likely an internal problem eg rings valves headgasket etc

failing that i would say turbo leaking oil out over the seals pull the intercooler piping off look for oil pull the dump pipe off look for oil when my 25 turbo went it smoked just like a burnout white thick and filled the streets doesnt mean to say your turbo sweet might just not be screwed completely yet!!!

Yeh mate i thought that first and prayed it was that but after i warmed it up wednesday for atleast 6-7 minutes then drove from my place in yangebup to kmart kardinya as i stoped at the lights there that white smoke appeared and thats when i ruled that theory out.It is very unconsistant but im noticing it happens more on a cold night/early morning but seen as tho driving for 10-15 minutes and stoping and it appears thats when i startred thinking the turbo's dying or oil in the system burning somewhere or worse case scenario the engine is the problem :P:P ...........but then again i mite just be freaking out :P

dont forget a TK test aswell, it'l let you know the condition of the headgasket although its unlikely to be the cause as the most common sign of a blown head gasket is tonnes of white smoke/steam right on start up which goes away and slightly difficult starting first thing in the morning, or if its bad enough commpression leak into the cooling system which is fairly obvious but from what infomation you've given its obviously not that bad. from what i can see its possible to be a leak from the turbo, possibly from the turbo cooling galleries may be leaking into the exhaust side, i dont think it'd be oil as oil creates a blueish smoke.

When I bought my car, the guy thought the turbo was f**ked, blew HEAPS of smoke on boost.. he had the breather hoses set up wrong..

The PCV is a little plastic valve on the outside of the intake cam cover, it connects via a hose to the intake manifold and allows the crankcase to ventilate when the engine is under vaccum but stops the crankcase from pressurising when on boost. It *could* be getting stuck open intermittently I guess.. allowing the crankcase to pressurise and blow some oil past the rings..

When it does happen, is it after a little boot? or completely random?

Thanks bubba il check it out if i get home b4 sun gets down today..

It is completely random most times but mostly occurs within the first hourish i run the car from a lenghty stop (6-8 hours plus).

I warmed up today 5-6 mins and no smoke at all so i drove around the block and no smoke either apart from a very small cloud on take off from driveway,tho i could do the same thing tmrw and it might smoke noticeibly its that random.

I spent hours yesterday checking over everything again and didnt see any signs of leaks or split hosings either so im out of ideas as to what it could be (externally) so im taking it to cypher this week sometime...and hopefully not receiving news of a valve stem problem..or worse :)

Sounds like turbo exhaust oil seal to me. Remember to keep checking your oil levels, and swap the turbo over to check if thats the culprit. I've been through a couple of turbos on the 180 now, sometimes it starts off intermittent.. though quite quickly degenerates to quite a lot of smoke. its usually fine for a few seconds on startup, then as the turdbot heats up it will start burning the oil. if you blip the throttle a huge cloud would come out. haha. I smoked out the entire driveway..

my aristo has a valve stem seal issue, not sure how similar it is to RB issue - it only happens on start up, then the VSS get warmer and expand, and the smoke stops. sometimes it can be quite a bit of smoke as well, but its always right on startup, after being left overnight or for all day etc.

as for headgasket, if theres no coolant in the oil and no oil in the coolant i'd say you are safe there.

  • 3 weeks later...

Got compression test done today and all were running the same (150 or 155,ive 4gotn already the actual figure but were fine) across all 6 cyl's so boiled down to being them valve stem seals.I went to a few "big name" workshops and was quoted between 1300 - 1600 with new seals and labour to fix...Is this a right price for this job or am i being RIPPED OFF bkoz i can get a new rb20 installed for around 16-$1800..

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
