The quick editing was from an error at my end which was sharply recified
And jerking the bar may give some relief at this moment but isnt going to help my engine
Right my heart is currently in my hand! Ive slightly loosened the first head bolt, at first is undid easily then there was a cracking noise and it went abit further and then went abit stiff. I undid abit more with a further cracking noise and now its gone stiff again,ive tightened and undone it with the wrench to try and free it up but its still abit stiff.
As the first head bolt has moved abit ive slightly undone the 2nd one that also made abit of a cracking noise and has gone stiff.
Im assuming the cracking noise is just the bolt loosing from the thread (or atleast i hope so!)
Im abit scared now, once theres a slight loosing should i go onto the next bolt?

Yes
As mentioned there is an order you are supposed to do it in (if you have not got a Haynes etc, shout out and I will look it up in mine)
There is not much you can do other than proceed and keep your fingers crossed. A bit at a time and a lot of back and forth is probably good.

I do have a haynes i know the order i just wasnt sure how much to slacken off a bolt before moving to the next, i dont want a wrong technique to spoil anything.
Thanks for all the help i will proceed and hope for the best
Thanks for the help it looks like ive had success at one side, all the nuts have come off and the studs seem loose but dont pull out so i think theyve just loosened from their threads rather than snapped
The only problem i have is removing the head, its slightly loose at one side but just wont come off.
Ive used a hammer and a rubber mallet, i know i shouldnt but i gently prised it with a flat blade screw driver but it still wont come off.
Well at least the nuts came off OK, Good news there then
Is the head stuck on the liner or can you not move it off enough to check that ?
A bit odd that it is loose at one side as usually, when it gets loose it would have released its "stuckness" all round. ( if you see what I mean )
It might be stuck on one of the studs ?
Plusgas, a bit of heat, and try and pull it off "square" ( I would go very easy on the levering technique though, too easy to damage summat - though I am sure you are being careful of course)
Erm... I worked out why the head wouldnt come off, i was tidying up and realised there were 7 nuts on the floor im sure you can guess where the 8th was
Oh well 8th nut removed and off comes the head with liners attached
All head studs complete and looking ok
I think its clear to see why there was a leak
Thats me done for today, tomorrow ill hopefully remove the other head and can think about getting the parts i need ordered
Thanks very much for all the help so far all of you especially ghost, though im sure ill need some more as i go on!
Just a reminder, though I bet you have read it by now, here is a link to a thread where one of the 80-90 members ( KarlT ) did exactly this job and he has included lots of useful info
The other head has now been removed with no problem, the studs look in good condition with no noticeable corrosion.
Great stuff

You can tell a genuine VAG recon because where the engine number was, there will now be a small circle with a VAG logo type thing in it. I think there is a date code too. Someone else might know the fine details more accurately than I do
Im still debating on what to do with the engine, just do the heads or open up the crankcase.
The issue i have is that if spend £200 - £300 on doing the top end and other bits like water pump etc then i would hate to put the engine in the van and further down the line have bottom end trouble which i had a chance to sort out.
If i was going to split the crankcase i would be tempted to replace the crank and main bearings, as they dont cost too much to replace and in my eyes they are the parts that will be most likely worn.If other parts looked ok i would leave them alone.
Ive looked in the haynes and it does seem quite daunting and i dont know what alot of the parts listed exactly are, but i have time on my side and an urge to fully strip an engine
I asked Ghost what he thought about rebuilding the bottom end and he suggested against it due to i assume my experience and the fact he thinks the bottom ends are generally strong and hold up quite well. He said it might be best asking some other folk so what do you guys think?
what did the case engine number tell you ? If it's a late ie post 2000 vw rebuilt engine I'd probably be happy with new oil pump and leave the rest of bottom end alone if it's being rebuilt as standard.
If it's unknown age recon then I'd think some more about it and others experience
I had a quick look but couldnt even find an engine number or a marking behind the big pulley,though i was using a 99p tesco torch and the batteries were running out
Ill have to take another look during the day when im next at where the engine is stored.
There surely should be some kind of marking there or an engine number im abit confused

Remember, if it was a genuine VW recon at some time in it's life, they take the original number off and replace it with a little round logo thing.
