Would anyone know the torque specs for the bolts on an M's oil pan. Also on the water housing gasket on the left side of the engine. Thanks. |

| True, the last pan gasket I bought was regular gasket material and not cork. That would certainly change the torque spec. That is also why there was no fear of over tightening. |

| rustred said: (quoted from post at 17:25:48 08/15/12) is that for a 5/16 bolt? |
Sorry, that is for a 3/8" (9/16 socket) Gr 3 5/16" NC is 17 ft/lb and Gr 5 is 19 ft/lb. I use the Gr 3 spec for all dot head bolts unless they have different markings.

I just found this one with a quick Google search, but the one I printed off and keep in the toolbox has what wrench size corresponds with what bolt size. I can be a dummy on that somedays. :roll:
That chart is tricky as it is dry torques. YOU SHOULD USE A CHART THAT USES WET TORQUES!!!

| the oil pan bolts are 5/16, so my guess on them was close. |

Yes you were. 15 is probably the oiled torque spec. There is no way you could wreck a gasket at 15 ft lbs. Not to mention the fact that the rim of the pan has the strips of metal to help spread out the force of the bolt. No way in heck you can evenly torque to 15 ft lbs by hand. |

I think he is saying that the standard torque for a 3/8 bolt may be more than needed for the cork gasket. |

| you would need a 3/8 inch lb. torque wrench anyhow to do that light torquing. it is not critical and just done by feel and watching the gskt. so it dont squeeze out. |

I have one. It is from Harbor Freight so I will probably get scolded for that. |

| I am not trying to sound like a jerk when I say this. Tighten it evenly, and just enough to squish the gasket where it doesn't leak. |

| This is the correct answer. Torquing the bolts is going to squash the gastket to shreds in places, Jim |

Curious about that myself. The correct torque should not destroy a gasket.
And for you folks that say to just tighten the bolts by feel, that only works if you have considerable experience in doing such things. A person with NO experience should always use a torque wrench.
If I can just remember where I stored some of my charts, I'll post some of the numbers. |

| With respect. A torque chart is designed to tighten bolts in samwiched metal, not 1/4" hick cork. When the gasket sqiishes out a little bit you will not be near the torque spec. Jim |

| but there should be a spec for the pan bolts. i would throw out a figure like 15 ft. lbs. on those 5/16 bolts. i believe if they were torqued to 15 lbs. the gskt would not be squished out. what i do is go around the pan about four times with a speed handle and you just get a feel when their good for tightness. say for example the bolt is good for 25 ft. lbs.in a chart, but your not torquing to that , just an even torque for the gskt. |

| There probably could be a guestimate, but differing gasket materials and pan straightness make it difficult to publish one that doesn't become policy when the policy should be feel and look of bulge. It is like the feel of making a basket in BB. when it is right, you can turn away before it swishes. Jim |

| I don't know of any. I printed a "standard torque" chart off the internet. It lists the torques for NC and NF bolts in Gr3, Gr5, Gr8. |
