Bluey White Smoke

[maddi68]

hows it going lads, i dont drive my st205 too often but i started noticing lately that if i leave it sitting up for a few days and then take it for a spin as soon as i drive off it gives a slight puff of bluey white smoke, it only happens when i first drive off after that theres no more sign of it, what could this be? stem seals? turbo? rings?

It sounds like to me either valve stems or piston ring oil control rings. This can happen if the cars been left for a time without being run. I'd check them befor going to the Turbo.

If it was the piston rings it would be more present when driving.

You can buy some seal regenerator, stick that in your oil as it may just be the oil seals are hardening from lack of use.

I'd say either valve stem oil seals or turbo seals weeping slightly

thanks lads i might just give it an oil change aswell, what grade oil should i use? theres 175k kms on it

It depends on how you drive it really, Millers do a really good motorsport oil 10w60 CFS fully synthetic, pretty sure the recommended will be 10w40 semi-synthetic but don't quote me on that
