st162 spewing white smoke on startup

[pr*duct]

Hi guys,

Just in the last week or so my st162 celica has been absolutely spewing white smoke on startup.
This continues to happen until the engine generates some heat (usually when needle one third of the way up temp guage)
I have noticed that this is not bluey smoke which may be oil but white smoke.

Wondering might this be a big problem with piston rings or valves/valve seats??

Any help would be appreciated...

Sure its not just condensation? most cars put out a lot of "smoke" but its only because its cold in the mornings

[slide86]

yeah. cold mornings = lots of condensation.

checked your collant level, white smoke (if it is smoke) usually indicates coolant burning

[urantia]

Yep best advice is keep an oil on all your fluids, if any of them are dissapearing then that's what your burning and can work out what the cuase is from there. Most likely condensation.

could be valve stem seals

Has it been extra cold in the mornings in the last few weeks as opposed to say .... summer That might explain the white 'smoke'. It's just that the colder, denser, air in the mornings makes water vapour more visible (something to do with dew point maybe?).

Valve stem seals would more than likely imply blue smoke ... so I wouldn't make that conclusion straight up.

tis condensation in the exhaust.
case dismissed.
if it stops when you get some heat you have nothing to worry about
especially if the car is running just fine

Possible leaking head gasket or cracked head causing water to fill cylinder over night and burn up on start up?

[love ke70]

if you were getting water in cylinder you would either end up with hydraulic lock, or it wouldnt stop burning away when the car warms up.

[30psi 4agte]

It takes a shit load of water to get hydraulic lock up !! and only a small amount to get white smoke .


If the head gasket is only weeping it will leak under pressure and not provide enough of a prob to be detectable when running only on start up after it has sat for a while and had time to leak excess coolant.

50 millilitres into a cylinder is prob more than enough to get lock up.
and why wont it leak when the engine is running? considering thats when the water pump is doing its thing and the water is flowing around/under pressure. and hot which would usually make gaps open up further.
also, if its leaking h/g why does it go for a few minutes if its only leaking when the car is off?
i think your clutching at straws
are we trying to make this guy stress more than necessary?

More then likely Valve Stem Seals

[love ke70]

tomorrow. im gonna take a video of my 1ggte with the fucked valve stem seals. you will notice that the smoke is super duper blue!!!! as they leak oil

It will still weep when running but it may be so minor that it will not effect the cars idle or drive.

If you notice the double cheezy in my first post this was abit of an indication that i know im going a bit far but i have seen this before several times ! mainly on falcons

More then likely Valve Stem Seals

The stem seals will cause blue smoke m8
