I am an over zelous retard who just got a torque wrench....Noticing some leaking oil around my valve cover, I started tightening!!! Bad move, I know only wish I had a Delorian and a Flux Capacitor.... Is there anyway to get 2 broken screws out from my engine block without having to go to a shop to get it tapped?

Thanks.

I'm an Idiot [?|]

for small bolts like that, often times you can drill a small hole in the center, and drive a Torx bit into it, then use the bit to back it out. I've found those to work even better than the extractors they make for that purpose a lot of times.

If you have a reversable drill, you can also buy a reversed drill bit, that bites going backwards. you often will get lucky and the broken bolt will back out while drilling it.

I have since gone and gotten it tapped...a little bit beyond my skill lvl....retail.... $138....Now I have to wait a little longer for my FS exaust...

Was the torque wrench miscalibrated or something? Torque wrenches are suppose to prevent this from happening, not cause it.

Be careful of the unit of measure. Some small nuts/bolts torque values are expressed in lb-in (pound-inches) or Nm (Newton meters).

For next time, there is actually such a thing as left-hand drill bits. You select a size smaller than the broken bolt, put your drill in reverse, and start drilling. Once you have a little dimple, push hard. The bit will bite in as it tries to drill and spin the broken bolt right out. It works great-- other methods make you hammer an extractor or something into the bolt which only expands it and tightens it in the hole. Sears used to have these drills, I don't know if they still do.

I did use a torgue wrench and I contacted my Local Ford Dealer and they told me to set it at 70 newtons....once I set the wrench I went at it and Snap.....so bad on Apple Ford In Lynchburg.....

The correct torque for a Zetec cylinder head cover is 7 Nm, not 70Nm. Its always best to have your own manual to eliminate the risk of misinterpretation or misunderstanding.
