    smoking

    Hi, The last few weeks I've noticed a large amount of smoke in the garage after I shut off my '00 Catera. Does anyone know of this problem?

    White smoke?

    Then it could be the head gasket. Especially when it's cold outside then you know he smokes heavily. The ride is nothing to remember, but stand

    Watch Out with your coolant level

    Re: smoking

    Most likely it's leaking due to a clogged Crankcase Breather Box. It creates high crankcase pressure that forces oil past the camcover gaskets. The oil settles on the exhaust manifold heat shield and smolders producing smoke.

    Solution? Replace the gaskets and clean the breather. Follow the links to the breather cleaning and gasket replacement procedures.

    Also when it gets cold the cats put out a lot of condensation, not to be confused with smoke. Oil will give a real thick-like smoke.

    Re: smoking

    Hey all, thanks for the words. I'm trying to find out the area it seems to be coming from but no definite luck yet. The smoke smells like a burning something to me, and it fills the garage and will stay cloudy in there for hours after shutting off. So I don't think it's condensation thanks tho.

    The coolant level is fine though also.

    A flashlight will hilight the smoke and expose its source.

    Re: smoking

    Hey, I have a 98 with about 47,000 miles. Noticed in the last month that it appears that the valve covers are leaking on both sides. This allows oil to seep down on the exhaust heat shields and smoke. It is especially noticable after driving at highway speeds and then bringing the car into the garage. Smells like something burning. I'm now researching how difficult it is to replace value cover gaskets. This may be your problem?
