Damit help needed

[TRD_ZERO]

OK i was in the process of taking the head off and when i got to the last stud i stripped the inside thread of the stud so i have nothing to grip onto. (had to fukn hapen on the last one) Now what do i do? How do i get this damn thing out?

[rollaholic]

is it a 4age head, with the headbolt quite recessed?

were you using the right tool

unless you have some big grunty drills my pick would be to get an engineer to drill the head of it off so you can lift the head off and remove the rest of the bolt

can u get a welder in there? why not weld a new nut onto the to of it and then use that i often weld wheel nuts to stuff when they get striped......just an idea not sure if it will work in the head you have but have heard of it being done

[79rolla]

did you strip the thred or the head of the bolt??

if its the head you could invest in some ezy outs.. just need to drill a hole in it first.. or perhaps use a cole chisle and nock the heaid off. if its the thred itself you need to lift and tern at the same time... or take the head off of it take the cylinder head off so you got more to grip

Yeah it s a blacktop head I was using the right bit but i was going in at a slight angle withought taking the cam out. the teeth inside the head of the stud where the bit sits into is stripped clean not the thread of the stud to block. I dont have a welder i might try drill it out.

Allgood now got it off wasnt too difficult actually just took a couple minutes.

yeah normally i would suggest welding another nut on top, but they are reasonably hard to get to.

good luck taking off the top of a headstud with a cold chisel!

so how did you get it out then?

[TRD_ZERO]

I bought a high tensile drill bit (10mm) and drilled down the center of it. It just popped off must have been alot of pressure on that stud. I was worried id go right through and start drilling into the head but there was a washer under it so that helped.

Yeah i think you would start to damage the head with a cold chisel.

Is there a special socket that u need to use? I think toyota recommends bi-hexagon 10mm socket???

it is a 10mm 12 spline drive. I had a few for sale a while back,
could probably get some more if people were interested,
but would have to check on price an availability.

its usually best to get the cams out of the way first..

Yeah i did take the one cam off as i had to, but the other one wasnt too bad but i didnt turn the cam enough and thought i could go in sideways but no. Thats what you get when trying to cut corners. Gave me a nice fright when i stripped it. But its all good now.
