white smoke is usually something dodgy with the engine but i would have thought it would be more so under load it would blow white smoke not just when its cold are you are its not like vapour ??? also black smoke is generally when its running rich

White is oil

Black is fuel

Blue is a combo of both....

Once i had to start this little datto 120Y that had not started in 2 years... I blew rusty brown smoke for about 5 minutes... LOL

Id say ifs its only blowing when cold. Could be a turbo seal givin out or a piston oil ring a bit worn... If youwant do a comp test when the engine is cold. Take this reading, then pump a touch of oil into each piston threw the spark plug hole, then do the comp test again. This will prove if its the piston rings and if yes then which piston is doing most of the mischafe... If the results are within 10% of the original test with out oil. Id blame a sel in the turbo....

Cheers Col

Blue is old-old-old oil dude... (thanks why 80's flacons blow blue, cause they were'nt serveced this centry... LOL)

New clean oil is white....

water will be condinsation, we just confirmed its smoke not condensation....

blue smoke is really a combo of oil and fuel....

as i stated above...

white is oil

blue is fuel and oil

black is fuel

Go and burn some oil using a wick and see what colour smoke their is.....

actually knackaz is right, blue is oil, black is fuel and white is water/coolant.

thats what i was taught at trade school by my lecturers who'd been in the trade for over 30 years so you'd think they'd be right.

:headspin:

:rofl:

white SMOKE.... SMOKE

read above before posting.....

Water/coolant is vapor, it will dissapear within a second of leaving the exhaust. Would not even see it from inside the car.

Go and burn some oil and see what colour it produces.... Dab a bit on your exhaust manifold and watch it smoke and then come back and tell me what colour it is....

I also admitted that blue smoke could be a sign of fuel and oil.....

In a skyline reving fuel is common to blow out.... More fuel may even cause a flash....

Ive had a fire in my exhaust before..... Busted the cat and destroyed the muffler.... But yeah.. Too much fuel and oil is a bad thing... LOL

    • Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?
    • So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch
    • It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.
    • As MBS suggested if this is happening when the engine is cold you're going to want to remove the intake air regulator and verify resistance + that the shutter is physically opening and closing. At -20C should be fully open, 20C half open, over 60C fully closed. At 20C should be 70-80 ohms. For AAC valve testing using a Consult cable see if you can raise and lower the idle by commanding more or less AAC duty cycle. Hopefully it's pretty linear as well, shouldn't be like 30% AAC valve is barely idling and 40% is 1500 rpm.
