I got a peugeot 207 1.4vti 2007 it starting to blow out blue smoke when iam at lights or in traffic it just had a new timing chain new exhaust and now this


indicates failed valve stem seals
when idling the vacuum in the system sucks oil past the seals down the valve stems and into the cylinder inlet ports behind the valve heads
on acceleration that small amount of oil is allowed into the cylinders indication blue smoke on take off
Blue smoke on hard acceleration is an indication of worn bearings as the bearings are pressed ******* the crank pin, enlarging the clearance on the other side which allows excess oil up onto the cylinder walls which the oil rings cannot control

What does blue smoke mean


Burning oil. Could be a couple of things. Possible your valve guide seals are warn out. If its blue smoke mostly when you first start the car, its likely valve guide seals. If its continuously smoking blue, its more than likely a broken or warn out piston ring. If its just every so slightly blue in tent, it might be worth a try to replace your PCV valve first. When the PCV valve gets completely gummed up, the pressure inside your valve covers has no way to vent other than forcing its way through the valves into the cylinders often times taking oil with it. Since PCV's usually only run out about $10 its worth a shot. Other wise, you've got a decent overhaul ahead of you for either piston rings or valve seals...on a 12 year old car most folks would either choose to scrap it, or live with the blue smoke while monitoring oil levels and watching for fouled plugs. Hope that helps and good luck!!

94z71 smokes when first crank or idolin


Sounds like valve stem seals or valve guides. The smoke would be blue, also going down hill against compression... Upon acceleration, you would see a puff of blue smoke.

Won't idle properly, smokes, does not shift right


Black smoke is usually too much fuel to the engine. Check main computer that controls fuel injection and timing.
Blue smoke is usually oil getting sucked past worn piston rings or valve seals.
White smoke = water getting into cylinders, bad head or intake manafold gasket, or cracked cylinder head or engine block.
