    Quick Help: m50 Rod bearing cap torque

    I need the torque spec for the crankshaft cap, NOT rod bearing cap for the m50. I'm changing the oilpan and i need the torque.

    Most people break the sump bracket off.

    But, if you insist on removing the bearing cap screws, you'll need to torque them both to 20 Nm (15 lbs-ft) then tighten to a 50° torque angle.

      if you're going to break the tab off, bend it back and forth until the metal gives, don't use a die-grinder which will throw metal shards all over your bottom end.

        We pulled the bolts out, and just sorta torqued it to whatever the others were at, its RDC. Really damn close. No angle torque, but it should be ok and its not my engine ;) Well, actually Aaron, we havent put the thing in .. oh wait. Gasket. Fuckit :D

          This is probably one of the bolts that you should avoid doing the 'gutentite" method. Damn.

            True, what we just ended up doing because it was dark already, late, waiting for a response, etc... was slowly creeping up on the ft lbs till one of the "tight" bolts just would start to nudge the slightest bit, and carefully applying that torque to the two bolts that were removed one at a time to pull the bracket off. I dont think it will be a problem. We refused to just do the gutentite method, at least a torque wrench was involved.

              Ah ok, I thought you just used a ratchet and your hands!
