If its white even after it warms up then it could be early symtoms of small blown head gasket, Or some synthetic oils burn white,
But you def have some sort of leak, like camshaft seal or camshaft cover seal, somthing like that. :roll:

TSRM says valve seals...my 6m does the same thing. Hiway driving burns nothing...but in the city i goes through oil like it's going out of style.

 

[jbrody44]

Are you going through coolant at all?

 

[Dragonfyre]

BHG possibility

 

[Dave A.]

Sounds like valve stem seals. Are you using synthetic oil?

Typically white smoke is a sign that coolant or water is leaking into the exhaust chamber. You can also smell it in the exhaust gas if you're burning either coolant or oil. Some day soon you should let the car idle in your driveway, and then have a friend apply the gas while in neutral while you stand back and get a whif of the smoke . It is a pretty ghetto plan, but then you'll know if it's oil or coolant without having to take things apart.

If it's oil though you would probably have bad valve seals or even small amount of oil in your spark plug holes from a bad valve cover gasket. If you pull out your spark plug wires and plugs, and find oil around the tips then that may be the culprit. If you are leaking coolant, it is most likely a bad head gasket or in an extreme case maybe a warped head.

no.

 

[DriftMe]

no.

werd, if it's bad there is no good way around it but to replace the gasket

replacing valve cover gasket

I need to replace my valve cover gasket. Can someone tell me how hard/easy this is, and how long it should take. I'm no expert, but I am a semi-seasoned wrencher.

How much $$$ will it cost?

 

[CJSREDPRA]

Cam cover gaskets???? WAAAY WAAAY easy!!!!!!!!!!

Right side cover: Loosen 4 bolts & it comes right off.

Left side cover: Remove intake crossover pipe. Disconnect throttle linkage. Loosen 4 bolts & cover comes off. You may have to wiggle this one out a bit, since part of the throttle body is in the way. Also watch for the curved plate that is attached to this one underneath. Want to make sure that this does not get bent.

Replace gaskets (you should also replace the 8 screw gaskets while you're at it), then reassemble.
