| - | ===== Aftermarket Head Gaskets ===== | ||
| - | Cometic MLS head gasket torque: | ||
| - | There are six torque values in sequence: 9-14-22-35-42-42 (all in ft/lb) \\ | ||
| - | When using aftermarket gaskets, it's important to note that the torque values in the FSM are for OEM gaskets. ((Hippysmack of the XLFORUM http://xlforum.net/forums/showthread.php?p=5793537#post5793537)) \\ | ||
| - | The OEM gaskets offer a squeeze factor unavailable with steel gaskets. \\ | ||
| - | When using the MLS torque specs, you'll find they are not that different from the FSM. \\ | ||
| - | For instance, after you get to 9 ft/bs, it's about a quarter turn to 14, then about a quarter turn to 22 and so forth. \\ | ||
| - | But using the actual values instead of counting turns gets a more even pull on all sides and allows you to feel when something isn't right. \\ | ||
