sheared oil filter cover bolts, I'm an idiot!

[Ribenapigeon]

I did a really reallly stupid thing. I over torqued two of the bolts holding my oil filter cover on. It was entirly my own fault, instead of checking the manual I 'remembered' the torque level for the bolts as 14nm. Of course after shearing the bolts I consulted the manual and its said 10nm. Luckily the bolts were standard M6x20 bolts and I had some in my tool kit and also enough of the bolts were left sticking out of the engine block to get a grip with some pliers and withdraw them. Otherwise god knows what I would have done. It just goes to show though that the old adage "measure twice cut once" or in my case "RTFM.....twice" is always appropriate. :-/

You sheared an M6 bolt with 14nm?!

Well 14nm is an estimate as the lowest setting on the wrench was 20 but I moved the vernier adjuster around to loosen it to what I aproximated was 14nm. Another stupid move on my part.

Those wrenches are pretty inaccurate at the extreme ends of their rated ranges - let alone past them. This was a lesson learnt by shearing off the bolts on my own oil filter cover on my Varadero =_=.

You're better off just going finger tight, then another turn or two in until it's tight enough to seal, rather than trying to torque it.

I did this too. I've been far too used to tightening things up until I physically can't tighten them anymore.

Phew glad I'm not the only one

This is why I still use an old stylee deflecting beam rather than a clicky wrench, when I even bother to use it at all. It's an aid to mechanical sympathy, rather than a replacement for it.

you snapped 2 before realising ??

Agree these are not critical bolts so no need to torque i hear a lot of stories of snapped bolts whilst using torque wrenches. whats wrong with nipping them up with a socket/spanner ? you can tell when its tight..

Engine bolts and heads criticle aqreas etc yes use proper torques .

I couldent find the old style ones anywhere

The first one I think I mistook the shearing for the click.

For a normal nut/bolt I'd do finger tight and then at least another 3/4 turn, unless it started to feel wrong. One or two flats would be too loose still, unless your idea of finger tight is different to mine.

Why the feck does everyone feel the need to use a torque wrench on everything??

On cars, and well everything else the only thing the torque wrench got used for was major internal engine stuffs. Head bolts, shit like that.

Only place we ever used em for anything but was at college, at we torqued everything up, including the wheel nuts. Lo and behold i had three studs come loose on my nova. Shits more hassle than its worth
