well last night i went to leave for work and got about 20 metres down the road and couldn't see out my rear view mirror from all the WHITE smoke so naturally i quickly pulled a u-turn and put the car in the garage and took the girlie's car to work as i was running late as it was!

Now i'd just put a new catch can on that i'd made and i just presume i didn't vent it properly (was trying to make it legal) which caused this mess!

Now this morning i put my old catch can back on which is vented with a filter and a few small 1/8 holes! I took it for a drive and it was still smoking but not quite as bad! I'm hoping this is just oil that was still in the exhaust etc burning off??? i pulled back into the garage and there was oily smoke coming from the engine bay (mainly around the turbo, can see slight oil marks/stains where the dump pipe meets the exhaust housing) and exhaust!

Basically have i stuffed something (can't see how?) or do i just need to vent my new catch can and wait for the oil to get out the system? I was reading somewhere that its illegal to have a 'venting' catch can but if you don't vent it properly does this problem i'm having happen or have i made it or hooked it up wrong?

Cheers in advance!

Have done this a few times as well and it seems to clear up fairly quickly and I dont think it will be damaged. :(

Probably idle it off in the driveway as some mongrel will see the smoke if your on the road and dob you in to EPA.

Your breather should by rights vent back into the airbox intake.

I had the same problem, the catch can has a breather in the system... should work ok, are you still getting oil smoke? You may of damaged the oil seal on the turbo? Go have a look at your intercooler, you should find oil deposits in there! Clean it out with metho/kero (ie drain it n empty until it runs clean, DONT tip the cooler upside down as the oil will run through it lol) and clean the pipes out then go for a hard drive to burn any oil sitting in the zorst and have another look to see if that helps, personally im still abit stuck with it all but im tryin the cooler cleaning next week.

i hope its not the turbo cause i've been through that with my old turbo and my new 35/40 is only 2000kms old so it better not be that!, i'm 99% certain its the catch can because it only happened when i installed the new catch can!

The catch can needs to vent to atmo or somewhere...crankcase pressure will build up and bad breath will come out somewhere else. Std breather goes back into intake pipe so instead just put a little filter off a hose tail on your catch can somewhere and let it breath off that.

this is what i thought but i heard that venting into the atmosphere is illegal with catch cans? I have my old catch can back on (the one in the pic which vents via a filter!) It seems to be fine, just getting all the oil out the system now is the pain staking part. Mind you it is still blowing a bit of smoke but nowhere near as much!

just took it for a quick hard drive and it only smokes a tiny bit driving normally but when it hits boost the smoke is much worse! To me that sounds like the turbo but considering its new and i changed the catch can and all this happened i'm still lenaing towards the catch can being the source of the problem???????????????????

just took the cooler off and there's a bit of oil in that which is probably causing the white smoke when the engine hits boost! Currently cleaning it now and will hopefully get it back on tonight fingers crossed!

Latest ZOOM has a great little article regarding crank case pressure and the ins and outs of oil catch cans and oil breather cans.

There was also a thread here recently where someone had a similar issue after putting on a new can and using wrong size hoses.

I think that thread started off saying “hi flow turbo blown” or something (because of the white smoke)

Even after fixing, there was a bit of smoke as the extra pressure had pushed oil past the turbo seals and so forth and was burning in the exhaust for a bit.

Hope that is all you have done and that nothing is broke.

    • 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"
