Make some Plasticine "reservoirs" around each stud and fill with penetrating oil or diesel and leave it for a day or two.
Keep up Stan, it's already been discussed in another thread also started by Mike.

Read this link on cylinder head removal on the LD10 http://ld10.awardspace.co.uk/bay/Cylhead.htm

34 - Remove the cylinder head by slackening the nuts a turn at a time, in the order specified on the diagram (Figure ??) until they are all loose. This will ensure there is no warping of the head due to undue pressure from the nuts. They can then all be removed in any order.
35 - Break the seal on the head gasket by giving it a few smart taps either side with the leather mallet. If this will not do the job, insert a screwdriver in the FRONT of the engine between the head and the block and gently lever upwards whilst giving the sides of the head smart taps with the leather mallet.
36 - Wiggle the head around to completely break the seal and remove. Try to lift it as vertically as possible to avoid damaging the threads on the attachment studs.


If you think that these are "butcher" methods, take it up with Darren and suggest a re-write :P

I think Stan was referring to the use of chisels to loosen the head.

^ maybe he didn't get the humour 8-)

Having said that, the LD10 reference does suggest using a screwdriver - verba volant, sed scripta manent

The link which Brian H has provided is all very well, but hardly authoritative - I cannot conceive of any reason why the engine must NOT be turned over once the rockers are removed

Keep up, Mike already tried that to no effect, see his post Sun Sep 12, 2021 10:44 am viewtopic.php?p=38489#p38489

May I ask where we should get "authoritative" answers from ? When undertaking repairs on a car, all methods and ideas are worth considering, as it's almost always based on anecdotal success, not "engineering" methods. As an example, use of heat to free something is anecdotal, the amount (repeat amount) of heat required has no engineering basis.

Your rude missive to Stan ( who has been a distinguished contributor to this board for many years ) " Keep up Stan" deserved what it got. You implied that "darren" whoever he is, was an authoritative source, when plainly he isn't

Gentlemen, please !!

Quite often emails and Forum responses can be innocently misinterpreted; especially where implied humour is concerned.

We are all here to assist each other where we can; combined contributions be they on the mark or slightly wide of it, all help to establish the answers and that is the ultimate goal.

Let's draw a line in respect of any previous misunderstanding or misinterpretation and push on to achieve that ultimate goal - that being to help Mike to successfully remove his cylinder head.

I'm sure we can all agree on that.

Regards.

I must keep up :D

Storm in a teacup.

It's very easy for forum posts to seem to be plain speaking (Wikipedia - the act of saying clearly and honestly what you think without trying to be polite) or close to rude, that's the nature of forums, we have to be mentally tough to survive here. :)

Humour 99% of the time is misinterpreted, that's why the use of smilies is advised as they are supposed to convey emotion or show that you are not really serious.
