please help!

I took off the timing inspection plate to see if the gasket was bad and it wasn't. So i put back together. Then, a bolt breaks and half of it is stuck in heads. How do I get it out?!!!

Beo honesnt body pulls that plate to ck the chain.

Most ck the cahin when the Valave cover is pulled.

 

What I do is drill the bolt where its busted on one side then I get a small indentation

get a punch then wack it so it goes counterclockwise

When the bolt breaks flush or better I weld a nut to it. When it's deep I drill and tap like mentioned. Idk easy-outs make me nervous I won't use it unless it is a very well made set and consequently expensive as hell. Sometimes a reverse drill bit will do it.

if there's at least a small amount sticking out, I use a dremel and a cut off wheel to cut a slot in the end. I stop cutting when the wheel gets to the hole surface. Then, if it's not stuck(sounds like it broke going in, but had been out before) I can use a flat blade screw driver to back it out.

If you have some sticking out, grab it with a pair of vise-grips.

[Guest DatsuNoob]

I like the vise grips method too (for some reason, I like the needle nose version best for stuff like this) but use a little PB blaster to lube 'er up first, let it set, wipe off the excess and set the vice grips tight. It should come right out.

Idk I believe if there is enough to grab with vice grips it is far from a problem lol.

[datzenmike]

Trouble is that it would be turned in pretty tight to snap off so you would need a good amount to grip onto, to begin turning. Thank goodness it's where it is as it can be drilled out to oversize and re-tapped as a last resort.

Ya sometimes with the grips you just round out or mangle the end real good. With that much meat though you at least have a host of easier options.

Same thing happened to me except, I was screwing out the bolt.

 

The vice grip method didn't work. I don't have a welder.

 

I drilled out the bolt by using the smallest drill bit I had and drilled the hole as close to the center as possible.

 

I switched drill bits to the next larger size and drilled again and repeated until almost all of old bolt is gone. Be careful not to drill into old threads. I then used a rat tail file to file out almost all of the remaining old bolt.

 

 

I then got the correct size tap thread maker, and rethreaded the hole into the same threads. It took me three hours or more :eek:

 

In your situation you can try drilling a perpendicular hole through the protruding bolt and push a cotter pin through the hole and twist the cotter pin clockwise. You could also try a nail if you don't have a cotter pin.

 

My situation was worse than yours because the bolt had rusted/corroded into the threads.

 

Valve covers, timing belt covers and most parts on cars don't need to be tightened more than half a turn past tight. :mellow:
