Hey guys! I've been having a problem with my 2000 4-cylinder Metro that I haven't found a thread with the same issue yet. About 75% of the time when I'm going from a stop I'll leave a cloud of blue-white smoke in my wake. Less often, maybe 40% of the time, the smoke will also be constantly building up while idling. What things can I look for to figure out what the heck is going on? The timing belt and all its component parts were replaced recently by a garage when the crankshaft pulley gave out and all my belts shredded themselves and sawed through the timing belt cover. I've had it looked at in two shops who I have little to no faith in - one replaced the downstream O2 sensor and the other did an exhaust system flush and neither thing helped. What's next? Thanks! Edit - forgot to say, the other threads I've seen have been about blowing smoke while at highway speeds. I haven't noticed any smoke once I'm above 10 mph or so, and I've been trying to keep an eye out in case that would help the diagnosis. Edited by Zii, Aug 1 2014, 02:28 AM.

Exhaust system flush? Some crooks just have no shame at all. I'd guess valve seals, they're known for failing on the 16 valve engine. Sounds as if yours have super failed. |

This kind of stuff happens to my brother-in-law all the time. He's the kind of person with too much money and not enough sense so he feels like people are actually doing anything at all to his car. I've told him 100 times to call me with symptoms so he can be specific when he takes his car in - but alas... I hope you mistyped "fuel system flush" or something similar. An exhaust system flush is on par with changing the blinker fluid or filling the frame ports with elbow grease.

Perhaps it was to clean oil out of the cat? |

Just my $.02...when the engine puffs coming from an idle it's either valve guides or valve guide seals...as stated above, this is common on the 1.3l 16 valve engine...and most likely you have already contaminated the catalytic converter...

I thought about that, but even then, they took it out, banged out some dust and put it back on. I have seen this spinning brush that some places use to ram up the rear of the exhaust and pretend to clean out soot, but we all know that doesn't actually do anything... People pay money for this. It's a disgrace to the whole mechanic/repair industry. We shouldn't need slight of hand and outright lies to make money. |

You are burning oil . Since you are going to keep adding oil until this is fixed, you might add (top off with) some Marvel Mystery Oil instead of your regular oil - which should be a 5W30 weight oil. Marvel (MMO) might free a sticking ring or lifter. ...but that is the claim and it is something you do yourself without being ripped off by a "mechanic." Get MMO at Walmart, follow the directions, don't over fill the oil.If you can use a socket wrench, pliers and a screwdriver you can change the PCV valve. http://geometroforum.com/topic/4193973/1/?x=40 It may be clogged. But at least you can check it yourself. Unscrew the air cleaner screw, remove its lid, pull the air filter up and see if there is oil and liquid on top of the Throttle Body. MetroDaveFor anything like a Compression Check or something mechanical you will need to either a) get a service manual, learn some new skills and do stuff yourself with the help (free DIY threads) and encouragement of everyone on the forum or b) go to http://geometroforum.com/topic/1644179/1/ and see if there is a Geo mechanic near you that can help you. they can also check to see if the cam timing is correct from when that belt was replaced. Hope that helps. |

It sounded suspiciously like blowing on an NES cartridge to make a game run better, but what did I know. I have a new go-to shop now that has a good reputation with all the car guys I know. Of course when I look for valve seals I find all the threads talking about blowing smoke at an idle. XD Thanks guys! |
