My gasket blew on my 91 Mighty Max and I'm about to blow a gasket myself trying to get the head off the block. I have it down to the back of the head with the camshaft off and headbolts out. Prying on it, the front has about a 1/4 in gap but won't budge anymore. I think I have to disconnect a whole lot more than I thought including exhaust manifold and the fuel injection. Any help, tips, advice, or pictures will help. She's my baby help me get her running like a sewing machine again

Hi and welcome to mightyram.You can remove the head without taking apart the valvetrain. I would've separated the the exhaust manifold and pushed it to one side and completely removed the intake manifold. You need to be careful about the fuel rail as it'll be pressurised and also careful you don't damage the 'o' ring in the fuel rail inlet. There is a brace that holds the inlet manifold up from underneath it - it is a biatch to get to but you should have better access to it through the wheel arch.

Removing the wheel on that side will allow you more open access to the side of the block so you can reach some of the more tricky nuts to undo. Good luck :thumbup:

Dont pry too much on that head or you will have to replace it because it is just aluminum also, there is a bolt properly left in somewhere you haven't noticed yet.... which is very easy to do. Did you take the head bolts off a quarter turn at a time in a star pattern? Its really easy to warp the head by just unbolting it. I have a feeling that i'm fixing to have to take my head off my 1990 Mighty max and get a valve job done myself. Good luck with your project
