C20XE crankshaft nut removal
Has anyone got any bright ideas on how to remove it? I've tried with the car in 5th, plugs in and a big breaker bar, but it's just pushing
the car along when I turn it.
Should I beg, borrow or steal an impact gun or is there an easy way to lock the crank from turning?

Borrow a big impact gun- they are famed for being on very tight!

+1 Impact gun - I buggered on a while back with an engine, locking the crank with a block of wood...
5 seconds with my windy gun and it came off.

Impact gun using the compressor is the best way, if you can get it in ok
Or in the past i've used a hot air gun to heat the bolt up and then its freed off ok with a breaker bar
Put it in gear and get somebody to put their foot on the brake pedal
(If it was out of the car you can drop the sump and chock the crank with timber)
Its good practice to replace the bolt aswell, unless you know its history

Thanks guys, sounds like an impact gun's the way to go. As for the bolt's history, it looks like it was installed in 1991 by GM and not
touched ever since

Old old trick and I have used it is to place a socket onto the bolt and attac a t bar / crack bar but rest the ens onto the floor then crank the
engine
Life is like a bowl of fruit, funny how all the weird looking ones are left alone

If you can get hold of an impact gun and socket then go for it. If not then big hammer and chisel will do it but you may need to replace the nut
afterwards.
Rotary build coming soon...

I just get someone to hold the brakes on for me, plus handbrake!
It'll have to be a pretty hefty impact gun for that BOLT!

I removed mine by wedging a drift in the fly wheel cogs and used a massive scafold/lever bar. Frustratingly, I was only replacing the pulley, and
didnt even need to unbolt it!

That's exactly how I did it, took less than a second to get very loose.
