well im an idiot....

LS Oil pan swap.
Was having problems with my torque wrench for some reason ......... think it was the angle.

I overtightened the oil pickup tube 10mm bolt and snapped if off ..... so mad at myself as usually Im really careful with that stuff in aluminium

What are my options here ? ........

Re: well im an idiot....

Not sure but that snapped bolt does not look correct...with that turned down end it most likely bottomed out in the bolt hole before clamping down fully....

Check the bore threads in the block for damage
Double check the depth of the thread needed and make sure bolt is not too long
I always dry assemble first then back the bolts out and apply thread locker to each bolt
Tighten to 106 in pounds....

Thats inch pounds

Lucky you got the broken piece out ok...

Good luck

Not sure. But it could have bottomed out by over tightetning.

Have another one in the head (not my fault this one) on exhuast manifold. What do you think - use a weld/nut or try the same appraoch with left hand drill bit.

See the "Eagles V Collingwood" yes Sir.

Re: well im an idiot....

If the bolt in the exhaust manifold is in the head it should be center drilled and a stud extractor used to remove the broken stud....

While you are at it, replace all the studs / bolts with new ones and make sure you use anti sieze on the threads when re-installing them...

Eagles v Collingwood...nah...I am Sydney born...more likely yo be Eels v Rabitohs....

Where you at mate?

Re: well im an idiot....

Here is a thread where I removed the broken exhaust manifold bolt on the LS in my '06 Silverado K2500 HD. Hope it helps.

Re: well im an idiot....

Curious minds gary.

Tried the easy out/left hand drill bit - no beuno on this one either.
So going to try weld.

Why does the weld not stick to the aluminium block though - I know its mig/steel wire not aluminium wire ....... but still thought it would try and stick and potentially the damage the threads etc.

Re: well im an idiot....

I have luck by plug welding a flatwasher to the broken bolt n then tackweld a nut on in place and then plug welding that mainly cause you can see the broken bolt and get a good well to it with washer then can weld nut solid to washer easier than to small bolt...I've just found this to work for me as working on big trucks every day I run into broken bolts often
