1G Removing broken valve cover bolts

[awesome]

I recently changed the valve cover gaskets on my dsm and when I was applying the bolts I heard a crack. I thought I cracked the valve cover but it turns out I cracked 2 bolts. Is there a easy way of removing the broken bolts?

Unless you can grab it and turn it out. It will have to be drilled out and you would use a easy out or stud extractor of some sort.

Remove valve cover and if there is still thread exposed use a good set of vice grips to grab hold of the remaining bolt. If not as above drill and easy out.

Cover-to-cylinder head bolts....30 inch-lbs
Cover center bolts..................26 inch-lbs

i was using 24 inch lbs when they cracked

Man, how poor of quality or condition must a 10mm bolt be to break at inch.lbs? I've torqued 10mm bolts to many ft.lbs without problem; the threads give way before the bolt itself does

evo-gsr has the procedure you want to follow.

i was using a socket extension. i didn't know it made a difference. but I'm learning as i make stupid mistakes

My mistake, socket extensions dont increase torque - extensions to the end of the wrench do.

Advice when using anything more than a 1/4" drive rachet is to grab your rachet or wrench close to the head so you cant get much torque on it. But if you were using a inch pound torque wrench then you just had crappy bolts and crappy luck. You COULD preheat the area around the broken bolts with a very small torch like propane that doesn't get hot enough to hurt aluminum but would expand it. I feel for ya man, I hate extracting broken stuff and have had to come up with some off the wall ways to get them out.
