Oh shoot...
OK all, I have a problem, I am in the process of removing the front motor mount so I can change the timing cover gasket, and I broke the motor mount bolt by accidently overtightning it How do I get the bolt out? I do not have a welder fyi.

Re: Oh shoot...
is that one of the bolts that go through the mount and into the front cover?
do you have the cover off? is the bolt broke flush with the casting or is it lower or higher? |

Re: Oh shoot...
did the bolt bottom out against the end of the casting or is it rusted threads or is it because the head bottomed cinched up against the mount.
if it isn't rusty and you twisted the head off, the remains of the bolt may be loose in the threads in which case maybe able to to slowly twist it out with your finger, but if the bolt bottomed out at the end of the hole you will probably have to drill it. if you had a welder or a friend with a welder, you could weld a washer then a nut to the end of the bolt and try backing it out. i hate easy outs but that may be your only option. |

Re: Oh shoot...
if you don't have an easy out.
i wonder if you were to drill a smaller hole in the centre of the stuck bolt and rethread it to a smaller size like maybe 5/16 or 3/8 then use a bolt with a jam nut on it, tighten the jam nut onto the stuck bolt and see if it will back out of the hole. if not you can always go to the correct size and drill it all out just thinking out loud i have not actually try this. if the cover is off and you have a drill press it is easier to centre the bolt. |

Re: Oh shoot...
I'd be inclined to load it on a trailer and take it to someone that can weld a washer and nut to it and get it out that way.

Re: Oh shoot...
I've had a lot of luck with broken bolts and screws like that whereas I use a small hand held drift and tap it hard with a ball peen hammer on the broken bolt's outer edge, in a counter-clockwise motion, around and around, it will come loose. I can use a Dremel cut-off blade to make a slot for a screwdriver also, if need be.

Re: Oh shoot...
It's a through hole, on the backside drill a center hole, with a file tang drive in the hole, files are hard and brittle so take it easy, turn the tang clockwise ....... after using penetrating oil
If your lucky just drilling may turn the broken bolt.

Re: Oh shoot...
Thanks for the help yall, Because I have some bolts lying around, I am going to drill the bolt all the way through. I will tap the hole and run a smaller bolt through it and put a jam nut on the bottom. When I go to pull it out, the jam nut will force the broken bolt to turn with the smaller bolt, releasing it. I am soaking the bolt in PB Blaster so when I go ape on it, it will come out no problem. Wish me luck!

Re: Oh shoot...
This bolt goes all the way through the cover on mine. so I can see both sides of the bolt in question.

Re: Oh shoot...
it is, there are no signs of any cracks or missing pieces, so maybe an aftermarket part? anyways I got the bolt out by drilling a small pilot hole and using a self tapping screw to grip and twist the bolt out. The problem I am having now is the front main seal, I am installing the two piece rope seals to help with my oil leaks and they will not let the cover sit all the way down. And the gasket for the cover doesn't fit quite right so I am in fits messing with it. so I am soaking the seals in oil and am ordering another gasket so I can try again. Thank God I bought extra main seals in case I goofed up.

Re: Oh shoot...
It can take a bit to get the timing cover in place with the rope seals. Put a bolt in one corner of the cover and a long punch through the other corner of the cover and on into the corresponding bolt hole in the block and lever it into place.

Re: Oh shoot...
Didn't think of that, I had to walk away and come back to it later or poor Sunny would have heard blasphemy toward Henry I'll try it with a screwdriver carefully in the morning. Btw, is it ok to soak the seals? they seem to have a sticky white powder on them and I heard that you don't have to soak teflon coated seals. This won't hurt them right?

Re: Oh shoot...
Many different opinions on weather or not to soak the seals. I don't.
I brush off the excess powdery coating and put a thin smear of RTV on the groove of the timing cover and the groove of the pan to seat the rope seals in. Then I put a thin coating of grease on the surface of the seal that the crank shaft spins on and assemble.
