Remove gasket/Hylomar?

[snowdude2004]

My bike is broken down at the moment and going through various checks. I have now come to a stand still as I need to remove my cylinder head.

Around the cylinder head there is some blue like stuff with a couple of tiny drips around the edge. Looking around the net I guessed that this stuff was probably Hylormar.

I've undone all the bolts and took out a stud because the bolt was rusted on the stud. Now its all done I'm trying to pull it off and am having no luck, so far I have tried cutting around the edge with a small blade and managed to get some off however I'm still not able to pry the bugger off.

Any ideas of how I can get this bastard thing off?

I would check all the bolts are free first. Make sure there are no hidden ones.

I agree with allymoss on this one. The liquid gasket shouldn't stop you getting the cylinder head off at all. Its only there to provide a seal.

What engine is it? Hylomar won't cause a head to be stuck on but a rusted head bolt most definately can.

the engine is a derbi one from a derbi gpr50, I've already checked around the whole head and there isnt any bolts still attached what so ever, there are only 4 main studs and then 2 bolts that go onto the head and thats it.

Yeh, Derbi 50 only had 4 main bolts.

I would say just whack it tbh, the head on that is pretty sturdy and if it breaks, they are only a few quid for a second hand one on ebay.

I'll go give it another attempt I suppose. At one side of the cylinder where its on the same side as the engine manifold it looks like its actually molded together, guess its whacky whacky time now then.

well I'm back, screwdriver will not fit at all so gave it a couple of taps around the edges and now im getting a little tiny bit of movement side to side but it still doesnt want to go anywhere. It feels as if its stuck near the temperature sensor now.

EDIT

Finally got it off had to scrape some metal off and shove a blade in near the back since the metal had joined slightly from rust.

Cheers for your help guys, much appreciated.

Good. Well done.

You shouldn't really ought to use a screwdriver between the gap between the head & barrel. The head gasket seal does rely on those surfaces having no bumps in them, which you'll surely put by levering in there with a screwdriver.

Even so, it's bad practice to use a screwdriver in the gap. Many heads have special tabs on them for levering against.

personally would have had the engine out, laid it down, block of wood and a mallet, tapping round the outside of it.
