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.

[old ugly]

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?

[old ugly]

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.

ok, a little more info, it is the passenger side motor mount bolt on the timing cover, no damage to the cover that I know of. I removed the cover no problem. But the head broke off, and it is tight enough where I can not pull it out by hand, or get a grip on the back side of it. I thought about drilling and tapping it, but I am a little nervous about ruining my taps, they used to belong to my grampa and I don't want to damage them

If you drill it to the proper size and are careful there is no reason that you will ruin the tap. I'd concentrate on getting out the broken bolt. Drill undersized first, being very careful to get it centered. Then try an easy out or a reverse drill bit. After you have the bolt out, then chase the threads with a tap.

[old ugly]

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.

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.

The cover is off.

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.

[Big hammer]

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.

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!

be carefull not to drill all the way through the cover, those are blind holes.

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

thats lucky
drill it from the back side and maybe the drill will twist the bolt out.


i have 4 of them here and they all have blind holes, wierd.

[Sunny the Model A]

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.

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.

[Sunny the Model A]

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?

[1crosscut]

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.

[nkaminar]

I just changed the front seal on my engine. I did soak the seals in oil but I they are the modern rope seals and probably do not soak up any oil. I did not use any sealant in the grooves. I had the pan off for another reason so I replace the rope seal in the pan too. I used the lever method that Crosscut talked about and eventually got two bolts started. I did not fully tighten the bolts and then went to the four pan bolts to bring the cover fully down. I replaced a leaking modern seal. The new rope seal is not leaking. I used a very thin coating of silicone sealant on the gaskets. A very light film of oil on the parts means that the gaskets will release the next time I have to take things apart.

If you replace the spring and trust plunger that pushes against the cam, make sure that it applies enough force and use some grease or assembly lube. I didn't check the force and had to take the cover back off to add some spacers under the spring to cure a cam gear knock.

[old ugly]

you can use a nice smooth socket that is a bit smaller than the crank to roll in that goose turd in. use a little oil on the socket so it slips easy, don't compress it too much just roll it in a bit so the cover goes on easier. the new goose turd may be a bit long and may need i tiny bit trimmed off. if it is way too long it will be real hard to get the pan on. i have trimmed some and others seam to go in nice.

We used to call them chicken sh*ts.

Thanks all, first of all, the reason I took the timing cover off was to replace the gasket as I had ripped it when I was installing a partial flow oil filter kit. I had a problem of oil being sprayed out of the front seal all over the engine bay, so I thought that I could kill two problems in one fix. I am soaking the seals in oil until the other gaskets arrive. because I do not like sitting on my butt waiting, I rebuilt the shift tower today so I can downshift without touching second prematurely. The shift ball on the bottom of the sift lever had turned into a square:0 and the clearance was 70/1000" off:0 so at least I got that out of the way
