the flyin' scotsman

Just when I thought that the stars were all aligned the 14th of 14 water pump bolts broke.

There's not much sticking out the block so I may be able to grip on to it with Vice grips but not for long if it starts to round.

For those who have BTDT should I drill/heat right away? Its soaking in WD40.

I'll post a pic in a min.

Use some good penetrating oil...

As for my broken bolt, I used the vise grip and it broke right off...

I ended up using a dremel with diamond tip bits to grind it all out.
If you do use diamond bits, don't press to hard, the bit will die real fast.

I also tried the ****er clock drill bit and that didn't work for me.....

good luck

If you can thread a nut on it, try that before the visegrip....

Heat did not do crap for me....

fyi, it took me about 5 hours to get that sh*t out.......

These will be a big help if you decide to drill. Earl G. turned me on to these.

Dan.............I may be able to thread on a nut but then?

DANdeMAN

Crap, from the pic it look's very "seized"!!

OK, the nut will serve as a sorte of sleeve and help to prevent the tip from exploding when you drill in it and then use a reverse extartor bit in it.
The reverse extrating bit is conic and exhort(sp) alot of lateral forces....

I'll post a pic of the drill in a few minute

Each bit as a drill part and a remover part......
According to some here, the stud sometime come's out as you drill - did not happen to me.
You can also turn the nut gently and hope the stud follow's the nut's thread but I doubt that it will happen.

Malcolm ... I've btdt and Dan is correct (lots of good advice here from everyone) but the nut is your best bet. Penetrate the living daylights out of the stud. Tap it hard with hammer and try heat, but do not try to budge it yet. Loctite it with the gnarliest loctite you can find making sure there is no oil on the stud, and then once solid, try to turn it wiggling back and forth. If it breaks, go with Dave C's recommendation. I drilledmine out center and was able then to get a screwdriver in there and that gave me great grip from the ID of the bol, but you will be better off with Dave's suggestion at that point. Whatever you do, stay clear of your block and block threads. Remember ... it's just an engine

Damn. Good luck with that. If there is room to get a nut on there, and you are unsuccessful at breaking it loose, at least the nut will help guide the drill (after all else has failed). I've had success in the past slotting the stud head with a dremel and metal wheel, but the last time I tried that it failed. If you can slot the stud, rap it with a screwdriver to try and break it loose, then thread on the nut to help support the slotted stud from spreading, an impact wrench with a screwdriver bit (hammer type) could work too. Just take your time. I swear by PB Blast, but some say Kroil is better...

May the shark gods be with you...

Weld a nut on it.

heinrich

Welding a nut may losen the chemical bond, but the water pump bolts are made of verysoft steel so they will snap long before loctite lets go, o you lose your grip on good pliers.

heinrich

Duuuude are you crazy? Maybe your nut, but definitely not mine. Ouch, Man!
