Blue puff of smoke on start up
 

I got a random puff of smoke on start up from cold this morning it's never done it before, it clears fast and does not do it when driving,

I have been told I need a catch tank could this be why I get the odd smoke? From the breathers or intercooler leaking oil in my exhaust system? Car runs and idels fine,

Thanks darcy

Mine does it once in a blue moon. I would not worry about. Especialy on a cold morning. Can be a touch of dampness in the exhaust or a touch of oil.
Just keep an eye on it and if it becomes regular then dig deeper.

I know what you mean though - I bit of an unerving feeling if you ever do get a puff of something out the back.

When a bottom end, head gasket or a turbo goes though from experience you do know about it smoke wise. Definately lots of it.

mine used to do that on start up, turned out it was the valve stem seals

thats what i thought mate, well its only done it twice once last night and once early this morning, just went outside and started it no smoke at all.

would this not do it all the time if they was gone?

mine didnt seem too, but mine only had a slight tear in one of them, which was just letting the oil drip through when the car was parked up, then on start up blowing it all out
