Smoke on start up

Recommended Posts

Hi all, I think I might know what my problem is but just wanted some confirmation and advice. 2000 2.7 tip with 80k smoking like crazy on start up in the morning and at the end of the day when I return home from work, little bit at other times depends how long I leave it to sit. Now I know the flat six is prone to a little smoke at start up but we are talking embarrassing levels here. No smoke during driving or on overrun, I'm thinking possible AOS, any thoughts/advice/costs etc appreciated. ps is there a way of bypassing the AOS to confirm diagnosis?

Technically yes there is -- there is a tube that goes to your intake from the AOS.

If you were to pull that -- plug the intake side -- you might be able to tell. But its also possible there is enough oil residue in your intake system

that you'll be burning off oil for some time.

however an easier method is to unscrew your oil fill and put your hand over top. If there is moderate to strong suction with engine running -- it's almost assuredly your AOS.

Mine was terrible on quick left hand turns.
