    Unhappy Stripped HCM Bolt Hole Threads - Questions

    2013 ST Limited

    I stripped the top left HCM bolt hole threads. I had the cover bolts cinched up at about the same torque as I apply to brake bleeders, then I applied 97 lbf-in (about 8 lbf-ft) to the top left colt and it stripped out the bolt hole. I asked the shop what they use and got 97 lbf-in as an answer. Huh. I'm really bummed.


    The owners and service manual don't say anything about how tight the HCM bolts should be. So I use the oil cover specs and apparently that's wrong. I would have thought that an oil change would be straight forward in the manual and didn't research it in the forum. Yes, it's my fault, but would have liked clear instructions for a basic service like this. Tighten is too relative a term for me.

    The shop tried to fix it by inserting a Time-sert in the cover of the hydraulic control module, but it failed when I put it in reverse. Now they are going to try by putting in a Time-sert in the hydraulic control module and then reinstall the cover. I read up on Time-serts and they were well received by mechanics. Hopefully, this will work.

    Questions:
    1) What does tighten mean for the HCM cover bolts? Equivalent of bleed nipples at 4 lbf-ft? I need a point of reference for tightening, even without a torque wrench.
    2) When I was tightening the oil filter there was a click between the filter and cover. Does the filter seat to the cover under torque? Should I have done something different? Space is tight and I couldn't remove or mount the filter and cover as a unit. Had to give a really good pull to separate the filter from the cover.

    Thanks

    97 inlb or 11NM is the spec I use.

    Wow, that's what I did and it stripped the threads! Don't know what to do now.

    As a rule of thumb... on low torque bolts snug and a quarter of a turn does it. Best is to use a short or 1/4" rachet where you can feel more. Longer tools will tend to strip or snap the bolts. A properly installed Heli-coil will repair the problem. If the attempted repairs have made the hole to large you may have to go to a larger bolt perhaps a SAE size heli-coil...this happened quite often on the SE models with the different size bolts on the oil filters...
