EVERY bolt is stuck?

[nathan k]

Decided to rebuild the engine my self, have been using you tube as my guide.
now I can't get off any clutch bolts, engine bolts, had to cut off two cylinder head bolts. getting fed up now. first what could cause all these bolts to get stuck? the engine was only rebuilt a year ago, did it overheat or something?

secondly anyone fancy trying to undo the bolts? I live in the new forest and would pay whatever as long as it's less than the extortionate mechanics. getting very fed up!

oh I've tried literally everything even bought a blow torch today to heat the bolts up and still no luck

How hard are you trying to undo them? Have you sheared anything yet? If not, you haven't tried hard enough.

*could* try a rattle gun to free them off. I have done this in the past but you need to make sure it's on straight and the socket is a good, tight fit because if it jumps you'll wreck the head.

You using an impact driver?

If the side covers are held on with Philips get a screwdriver blade like this - stick it in the screw and give it a sharp "knock" with the hammer about 4 or 5 times to break the seal. Then use the mole-grips on the screwdriver blade pushing as hard as you can to stop it slipping. If the heads are already knacked - you're screwed

Are you soaking all these bolts in PlusGas?

One of these things is a very inexpensive friend at times like this:-

"Stripped bolt" - a bolt that has had the thread stripped off the shaft - usually from over tightening.

"Rounded Off" - a bolt that has had the head rounded off - usually from using the wrong sized spanner

It does take a bit of patience at first but you get used to it and soon learn the best way to remove certain fasteners. Stick with it.

Thanks for the help so far,
ordered some plusgas stuff and will borrow a friends impact screwdriver tomorrow, fingers crossed!

I usually tighten them up a little first.
Just enough to "crack" seal which has formed over the years.

If you have further issues it might be worth (if safe to do so) to try and bit of heat on the area as if the bolt and the metal around it are different they will expand at different rates so can sometimes losen enough, I would suggest plusgassing it first though, ive only heard good things about it

[nathan k]

finally got round to trying out the plusgas and impact screwdriver as was ill last weekend, worked a treat.
going to try and get a video up to explain what's wrong with the clutch as i'm thinking the engine probably dosen't need splitting.
thanks for all the help so far!
