That left over 1% can be a killer! Or a life-saver! Some types of gas lines have left-handed threads, so you can connect them wrong or take them off by mistake. Jeff |

Those are great for older vehicles and for things like motorcycles that have a wet clutch. The newer oils don't work well in those applications as the additive package cause problems. They won't cause problems in newer vehicles though. -- Steve W. Near Cooperstown, New York |

You can lie under the car > with your legs sticking out in any direction you want, clockwise is > still the same direction. Seriously. Try it. No, I am not trolling. Several responses that did answer the question without any sort of smart remark whatsoever referred to the possibility of left handed threads, that is why I was asking. I don't want to turn the bolt what seems to be logically counter-clockwise (i.e., towards the left when facing front or towards the right when facing rear) and end up snapping off the bolt due to over torquing it. |

Use the star tightening sequence. ======== Hls, I think your answer is important enough that I'm going to re-post it here under the main thread to make sure I see it in case I feel the need to re-read this thread 6 months from now when I first change the oil. |

"Daniel W. Rouse Jr." > wrote in message > Several responses that did answer the question without any sort of smart > remark whatsoever referred to the possibility of left handed threads, that > is why I was asking. I went back to your post and didnt find anything that I could correlate with a question about left handed threads. My response to you was not intended to be flippant. You did not seem to know how to perceive "clockwise". A post told you that left handed threads are rare in cars. They are. Some Chrysler products used left handed threads on lug nuts on one side of the car. ( It wasnt necessary, but they did it anyway). I believe some fan clutches may also entail left handed threads. When removing bolts, you might not have any way to know if a left hander is hiding there. So proceed cautiously. Lots of right hand threaded bolts have been stripped and broken off by people who get too rambunctious with a wrench. |

The first thing I do is I loosen the filter until there's a gap between it and the engine so heat can escape. The oil film on the gasket helps it seat better. It must be important because when o-rings for air conditioner hose assemblies aren't lubed, they leak like crazy. |

If you have a GM belt tensioner with a flat idler pulley it has a left hand threaded bolt securing the pulley to the tensioner. Just replaced another one on a vehicle that the owner tried to "repair" by replacing the idler. OOPS. -- Steve W. Near Cooperstown, New York |

That basically means they shave the rat. Put a product soaked cotton ball on the spot and tape it there. Then they replace it with a new one every few hours or just shoot some more of the product onto the cotton. Not a realistic test of what really happens. I doubt there is anyone out there taking baths in used oil. or soaking their clothes in it and wearing them while dripping oil. How about this warning.
