smokey 1jz

hey,
over the last couple of weeks my 1jz-gte has done this weird smoking thing about 3 times.
Its when you have been idling for a longer then normal time (around 5 mins), it starts steaming out the exhuast. Im almost positive its steam. It doesnt smell like oil and it has that steam feel when you put you hand in front of it.
Once you start driving it goes away. Which is weird.
Im really not sure why it is doing this. Could it be a slight prob with the head gasket letting water into the cyl's ?
Basically its a stock 1jz-gte in a ma61. Car has been on the road for about 2 months. It doesnt overheat and it doesnt loose oil.
Im kinda stumped as to what it could be.
Any advice is appreciated.
cheers
nathan

Valve stem seals, turbo's, cam seal leaking into plugs.
That's all I can think of.

but it only does it when idling for a long period
start-up, normal driving and boosting dont produce any smoke
if it look/smealt/fealt like oily smoke then i could start looking at things but it doesnt use excess oil
could a fuggered pcv valve do it ?
going to look now

ok re-checked all fluids etc
all is good oil still full, rad is slightly down but my refill tank is mounted lower then the rad top.
The pcv valve passed the blow test. Would blow out from the motor but not back in. I also noticed there is a little oil residue around the oil filler cap which could mean the pcv is fuxored ?
I guess the thing that makes me wonder is how is it making the smoke ? as in if its not burning oil or water then what is causing it.
thanks for your help man

Do you have the old type PCV valve with the big kinked hose or the newer type, check my site for the newer type.
If it's an older type get it replaced. It shouldn't allow the engine to be pressurised. So you are right.
If it's steam, then I have no idea. Start of a BHG?

does it have power steering
i have had a faulty idle up vavle that sits on the side of the power steering pump
this was allowing power steering fluid to leak into the manifold
only did it at idle sometimes
and at start up
is your power steerinmg fluid low?

That's a new angle sideshow. My idle up valve was taken out. It should have a one way valve on the hose anyway?

Yeah sorry no one way valve on the P/S idle up. Mine has been blanked off for a while as the aircon fittings wouldnt fit with it on.
I havn't any problem with it stalling and turning at the same time. If it feels a bit low I just give it a blip.
On another note, with your engine oil, try a thicker oil, 10W40 or 15W40, fully synthetic.
I found that 5W50 Mobile 1 was too thin, I think your engine will feel a lot healthier on a thicker oil. Do this for your next change.

describe healthier 
the thinner oil would result in lower oil pressure to yea ?
been thinking thats a little low
going to blank off that valve and see how i go. just going to have to wait and see if it does it again i guess
the car as a whole i love just trying to iron out the bugs.

0W and 5W is deisgned for new or rebuilt engines. Our engines are old and have done a few k's. The thicker oil is recomended out of the factory anyway. I strongly suggest using 10W or 15W oil ASAP. It will result in less wear on engine parts as well.
Currently I use Motul 10W40, It's a great oil, I might even see what other brands are good next time in the 10W range.
Let us know how the p/s goes.

HPR15 is the way to go for 1jz oil. it's never driven nicer, and doesn't burn any

dont stress about it naten
i know of 2 guys cars this happens too and they have had the issue for 2 and a half years, they have never blown a turbo or an engine, it is thought to be the rear turbo leaking a small amount of oil, from memeory they found give the car a few quick revs made it go away for another 5 mins. i wouldn' stress about it. i run penzoil gt performance in my 1j its 10w-40 and it works a treat. its well priced also, its only about $29 for 5 litres.

yea i feel a little better now
i changed the oil out yesterday for some HPR15, its 15/60 semi synth. seems to be a heaps better. It idles almost spot on now and barely misses at idle too.
I have tried to get it to smoke a few times last night/today but it seems to have stopped
it was either the shit thin crappy shell oil or this pipe that was running off the intake to a little carbon canister thing. ma61 owners can prob help identify it a little better.
basically a pipe runs off the manifold into small carbon canister looking thing, it then runs to a electronic pressure release valve thing, then into the valve that controls the flow to the heater core.
nfi what it does
so it wasnt either one of those but im happy cuz it seems to be fixed now.
thanks for eveyone who helped out.
cheers

That is the vacuum line for the heater. The canister provides vacuum to open the actuator behind the dash and to open the heater tap on the firewall, thus allowing hot air to flow in the cabin.
If either vacuum line is disconnected, the heater wont work.

ok thanks, i figured it was something that controlled the heater but didnt know what the canister was for. heather doesnt work anyways so i will leave it off.
if anyone has any clutch suggestions im all ears too. clutch is fubar. its a rpm 'heavy' kit that slips like shit.
Im running a w58 so anything that fits a 7m will fit mine.
Im thinking the best option would be fuck off pressure plate on an organic clutch?
