Intermittant Smoking

Howdy all

On my S14 ive noticed that after a drive and the cars warmed up, when i park it and idle it for a minute.. it starts to smoke a bit. When i start the car in the morning, it doesnt smoke at all.

The previous owner said that the oil feed lines to the turbo leak and cause this. Do you think its the problem? Or could it be worse like the turbo itself going?

Thanks a ton 🙂

if the oil feed to the turbo leaked the smoking wouldnt be out of the exhaust, it would be in your engine bay.

it could be the seals on the turbo leaking slightly, but then its likely that it would smoke slightly under acceleration not idle.

usually if it on idle, when the car is on vacuum, its the valve stem seals in the head, cos slight amounts of oil get sucked down into the combustion chambers!

The annoying thing is, it doesnt do it all the time either, only after an uphill.

How much is it to replace the valve stem seals on an SR20 ?

Sorry i need to brake the silance....if your car starts to smoke after a while when it idles this is normally a turbo seal problem, but then it would keep on smoking for a while.

You say this happens only after an uphill, mine did the same although I have Ca18, it was a breathing problem.

Try this to see if it is Valve stem seals, drive the car hardish...say in forth then just take your foot off the petrol and let it vacuum, don't take it out of gear, as you slow down if you see smoke at the back that is a good indication for vss.
