I am trying to remove the manifold headshield bolt and was unsuccessful!

Tried WD40 by soaking it in kitchen towel - feck all.

Tried hammering around the head to loosen it up - feck all.

Heck I even tried heating it up using the mini torch - feck all!

How the hell do I get it out? The head is almost rounded!

Someone suggested pouring diet coke over it, but don't kn ow if it's going to work...

Any other ideas? I have access to limited tools, but I do have gripper (which didn't work)

Thanks,

dojj

do you actually NEED that particular bolt? if not i would just grind the head off

dojj

iTrader: (3)

how would he get the remains out?

AJ_ERST

weld something to it? you could try filing the sides flat to get something on it

when i waas doing the head gasket two head bolts snapped i used a pair off mole grips then tightined them with another pair of mole grips worked mint try that.

Drill it out or gring the head off

plus gas, is a good fluid to free stuff like that, better than wd40

i was told this by an engineer, failing this, do you have enough room to drill it out using a smaller drill bit than the bolt, then pick the thread out? so the hole isnt damaged for new bolt?

dave green

simple, Heat with a welding torch

foreigneRS

you should always tighten stubborn bolts before trying to undo them

alex had a brilliant set of tools that i saw the other day for gripping onto knackered bolt heads. they were made by irwin, but i don't know what they're called. i'll have a google about and see what i can find

EDIT: not found them yet

they have a kind of spiral inside that grips harder as you twist undone

I'd try a combination of all three. Plusgas is blinding stuff. Then file it back into a good shape to get a decent socket on it and combine this with the heat treatment.

Erm arnt they the one's for snapped stud's that you cant get anything onto but you drill a small hole than screw into to remove? Look's like it on the piccy anyway.
If it is them they're shat!
Used them allot cos i for some reason i seem to snap manifold stud's a lot

Use them at work quite a lot, well i do anyway, to make swift work of dealing with my fuck ups

foreigneRS

no, them things are shit - eeziouts

these things work on bolt heads. i don't know what they're called. i'll have another look

foreigneRS

here we are



http://www.irwin.com/irwin/consumer/...rwinProd100512

and they do them in sets. gonna order me some up now that i've found them - EDIT - can't find them available online

eeziouts are good, just need to centre drill the threaded bit of the bolt you are removing, they are for if the head has snapped off. No other way of getting it out then!

foreigneRS

they are good if you've got good ones and use the right size drill bit and have the proper tool to turn them evenly with i suppose

mrjenrst

Yeah mayby but....

You use them where the stud has snapped because they're usually fucking tight and the one's i have used i've snapped aswell

Nothing better than drilling them out

Used the other female type one's and they do the job

borderfox

Machine mart stock them...... Good job....

tsutton

dojj - lol, I might... but it's dark, so will take a photo tomorrow.

fraser9764 - nah, don't need it. Got a new one. Just need to get the damned thing out! I don't have any tool to grind it out, which is a problem.

lovetheclassics - no welding kit here.

rst in progress - Yes, there is *just* some space for me to drill it out, but don't think I have some metal drill bit. Just drill bits for wood.

All: Thanks for the replies. Some suggested using a oil penetrating spraycan or something.

I am going to try the easier way which is using a hacksaw to cut the middle of the head and using a flat head scredriver to unscrew it - would this be easier?

Thanks all again.

...if you cant get purchase on it using a socket/spanner then you've got a cat in hells chance of getting it loosened using a flat screwdriver....sorry mate!

i personally think the slot with a hacksaw and screw driver approach will work, if its that tight you need to work at the problem of why its tight i.e un siezing it with something like plus gas as suggested

turbo sockets!they are the bollocks!

Might go there tomorrow if I can't get it out using other methods.

For now, I have soaked the rusted bolt with WD40 and kitchen paper and leaving it overnight.

Will see if it come loose tomorrow morning!

mrjenrst

Just spray holy water on it and wait for god to take it out cos you've got more chance of that, than the above

pani_k

iTrader: (1)

another one for the heavy duty extractor (turbo sockets). Once you get a snug fit with one of those babies there aint no chance in hell the said bolt isnt going to give way!

I hope your next post isn't gonna be -

'Forgot to take off the oil soaked kitchen paper from my exhaust this morning, drove the car, its now gone up in flames'

Just go careful with the slot and the screwdriver, only make the slot just big enough for what you need

gingeRS

i have a stubborn bolt on my manifold heatshield that i cant seem to remove, problem is those turbo sockets only go down to 8mm, and think its 7

any other suggestions, looking like cutting it off with the dremel at the minute

tsutton

LOL, have no plans to use the car till it's all done.

I had a think overnight and I think it will make things worse, so I'm going to get the 5 piece bolt grip set from Machine Mart assuming I can't get it out this morning with a gripper.

remove the manifold

send it to a machine shop

go and buy some bufty bolts

replace

bufty away with bufty stuff from a bufty shop

everyones happy

tsutton

The manifold bolts attached to the CAT are rusty too, not going to do the extra work all for just one bolt on the top!

tsutton

Right, back from my car - the overnight soak of WD40 and kitchen paper did the trick - I've finally removed it at last!

I'll bet dojj still want to see the pic to poke fun at me...

gingeRS

for anyone interested

http://www.amazon.co.uk/Irwin-Bolt-G...0931531&sr=8-1

just bought a set

tsutton

gingeRS, thanks. Machine Mart has it for Ł19.96 inc VAT for anyone who need it now.

Starting to look like I may not need it as I got it out. But then it might be useful for future.

It's pissing down with rain at the moment, so can't carry on with working on my car.

gingeRS

well i'm hoping that the set will help me remove this stubborn f*cker tomorrow

tsutton

That looks like you can spray WD40 on the threads and leave it to go through the threads, covered with kitchen paper like I did.

Unless you've already done that?

gingeRS

no its the bolt, not the nut.

the top one

frog

Loctite to a lubricant spray like WD40 which comes out freezing cold from the can, meant to help un-seize stubborn stuff by creating a bit of a thermal shock.

Might be worth a try - Halfrauds stock it irrc.

gingeRS

freeze release???

have some at work i am 'borrowing' over the weekend
