How was the oil when you dropped it?
Any metal particles in it or lumps? Often hard to see really fine metal if there is any
How about the oil filter - was it clear?

It turning over by hand looks encouraging though so you may be in luck

Ok yeah it turns clockwise, but as I mentioned there are turns with more resistance than others and when it does theres the sound of air escaping somewhere, if I wait for the air to escape then its no longer as hard to turn. Also as I mentioned there was some clicks/clunks.

I havnt had a proper look at the oil yet but the pickup pipe just looked a bit clogged with black sludge.

@doylebros start it without the fuel pump? So I dont need to take the fuel pump out, just the fuse? May I ask why? Also there is no oil light on the dash at the moment, but there may be when I turn it on I guess.

Your not wanting to run the engine just get oil pressure built up - like I said your best waiting till Saturday for your dads mate.
If he's a no show then you'll have to be guided but let's wait and see if he turns up.

That seems logical.

So should I not worry about the occasional clunk and the air escaping? It may be my mind but it did seem easier clockwise the whole way round then anti clockwise. Sorry for all the questions, I really apreciate the help

Your engine runs clockwise and thus should be turned in that direction.

Other than the single click in the video the video showed great promise - the air escaping noise is typical on the compression stroke - two full turns of the crank nut is needed.
Now engines with bent valves and snaped valve guides etc turn over as well but it's more promising than a seized engine.

Ok well thats good.

When turning clockwise on the first rotation I did hear maybe two clicks that were slightly louder. So does bent valves or valve guides mean new head and not new engine? Could the rods be bent?

Anything is possible but let's just relax and give your mind a rest - Saturday will be there quicker than you think and you'll have a chance to see the outcome unfold before your eyes.
Do your sums on an exchange engine from a breakers yard and you'll have your ball park figure.

I personally didn't want him to do it just in case there was metal to metal friction but now I've see the video all sounds promising from here on.
As doylebros said, that's the compression stroke.

If the rods were bent you'd get no turning of the engine at all :happy2:

If valves are bent then all you'll need are cylinder head gasket, valves, guides and seals. Maybe a timing kit and water pump would be good at this point of you've not done so already. sorry so many posts I forget who's done what to their cars  :stupid:
Happy to see its not the bottom end goosed  :smiley: :smiley:

I don't see how turning the crank shaft by hand could possible do any damage without the sump on, oil pump won't even be working at that speed.

Valves won't be bent if there's compression

Engines can still turn over with bent conrods.

I would think having no oil to lube the metallic components would score certain parts but maybe I'm thinking about it all wrong here? .

If the rods were quite bad then I'd say it wouldn't as I recall ad having bent rods in an engine I bought second hand in my youth not realising the fecker conned me out of £60 at the time lol not big money but still hard earned money. Not evidence of engine knock was mentioned by Pesky so lets wat for his dad's mates opinion on this.

@Peskyjones what I meant was you didn't say the engine was knocking?. clatter clatter type.

A few turns will do no damage at all and there will still be oil on all the important internals anyways, it's no different to turning it by hand than it is via starter motor. Only different is your not turning it over fast enough for it to start.

I agree  :smiley:

Not sounding good pesky, could you tell whether the noise was from top or bottom?. Was it a metallic noise more than deisely?.
I'm wondering is if your hpfp tappet has anything to do with this?.
