Overtightened valve cover

Just put a new vcg on and im thinking I overtightened my valve cover by quite a bit. Is this goint to cause a problem. Can I still loosen the bolts and retorque them?

The key here is that nothing was snapped/stripped. If you are sure you overdid it, then I would loosen the bolts and re-tighten them in the proper pattern using a 1/4 inch drive ratchet. Keep going until the bolts bottom out and then give each one an 1/8th turn afterwards for good measure.

You can't overtighten the VC.

The nuts have a sleeve that will bottom out with the stud nut below. It's supposed to do that then tq to 10-14ftlbs-- I forget-- I just turn 1/8 of a turn once it has bottomed out. This mean's the sleeve will touch the top of the nut stud. So no you can't overtighten the VC. What CAN happen is snapping the stud of lol

Yeah just did mine tonight. They bottom out and then the torque wrench will snap at 10 Nm. I have done this several times and have not broken a stud yet.

Foot pounds is too much.

No! They're to be 6 ft/lbs. Better yet. Don't even torque. Just tighten until they stop, then try a little further. Anything more and you'll strip it.

before you do anything, go buy a good torque wrench. Trust me, it will pay off for years to come.
Loosen, tighten and use a torque wrench to finish off.
Ensure you have a new VCG just in case it leaks. VCG are supposed to be one time use.

I just get to 'bottoming out' and stop. This is the first I've heard of going 1/8th after bottoming out. I think that that might be enough to snap the stud...and it's because of using a 'too large' torque wrench that this happens at all. Tighten from the center out in the prescribed pattern in stages.

Some here 'bottom out' and then back off each screw a little...so bottoming out is enough. If you didn't break a stud, I'm sure you're fine...as long as you did do it in the proper pattern in stages.

Yeah I did everything in the proper steps and then I tightened until it wouldent go anymore but I put some effort in, any more I would have stripped the bolts. Do you think im good or should I still go and do it over? Worst case I have a spare EZ vcg that came with my vanos kit.

Bottoming out is what I meant.
