Valve cover bolt sheared? Help needed!

Changing glow plugs so I got a brand new Digital Kobalt torque wrench. It worked well for torqing the glow plug to 14lbs but when closing up the engine, not so much. I set it to 98 as stated and the valve cover bolt with the stud on top for the air intake hose sheared clean with nothing sticking out.I do not reccommend this 200$ wrench. As luck would have it I dropped one of the other stud on top valve cover bolts for the oil stick also and cannot find it.

Question 1- Can I drive it with 1 missing?

2- What is the part number for the stud on top bolt? Where can I get a new one? I have Googled and come up empty. Please help.

Re: Valve cover bolt sheared? Help needed!

Are you talking inch lbs or ft lbs? If you torqued them to 98 ftlbs they will shear off every time. Factory specs only call for 72 inch lbs or 12 ftlbs.

For the stud just pull one of the bolts out and head down to the parts store and just tell them you want a stud a inch or 1 1/2" longer than the bolt along with a couple of nuts.

Those studs are metric, M8x1.25 (IIRC). They're kinda special, as the hex/nut is integral to the stud, not a seperate piece.

Here are some:

Hardest part might be getting the broken piece out of the head...

Just spin it out with a pick or something. If that doesn't work get a left handed drill bit.

98 inch lbs. Big difference, 12 times the difference actually.

Re: Valve cover bolt sheared? Help needed!

I don't know if I would pay $40 for something that I can fix with a stud and a couple of nuts.

Place one nut on the bottom of the stud to act like a bolt. You'll need 2 nuts on top to tighten it up but then just take the two nuts off and just use one for the attachment. Then if you have a welder or a friend with one you could tack the one nut into place so that you wouldn't have to deal with the top nuts.

You should be able to do that for less than $5.00

He said it sheered clean with nothing sticking out. I assume he means flush with the head. If there is some sticking out then the nuts wount even be necessary. Just spin it out with your fingers.

You could also just head down to your local ford dealership and pick up a bag of valve cover bolts...done it before.

Shoulda bought a Cummins.

I was talking about the replacement one.

I figured that he should already know how to get the broken one out of the head.

But a nut and welder can do a lot of things with sheared bolts/studs.
