head wont come off

[shamirj]

hi all

please take a moment to have a look at my seized motor tried pouring oil and diesel down the spark plugs but still wont turn over after weeks of sitting idol. here is a pic with approx 10 bolts removed some 4 short bolts, some larger ones but the head wont budge, what am i missing here. i thought a small tape with the hammer would suffice but no way. do i need to remove more to take the head off cheers this is a 86 inch 55 model s1. curious to see whats seizing the motor stiff

Inlet manifold?

Not familiar with 2Ls so can't do a bolt count for you.

You will need to remove the rocker gear first.

Just make sure to keep everything in the same order as you removed it.

The two nuts holding the rocker shaft I suspect also hold the head - certainly the manual I have says to remove the rocker shaft first.

Also, the distributor must be removed before the head, although I don't think it actually holds it down, just stops it being lifted off.

The manual also calls for removing both manifolds first, although as far as I can see it is not essential.

as above strip everything but the manifolds, use the manifolds to lift the head with.

occasionally you can get electrolysis holding the head to the gasket to the block but its usually not that tough to beat. If your up against that put some gentle upwards force on the manifolds (I use a over head rafter with a pully block) then some light taps with a plastic hammer.

As others have said + I think there's an oil feed line (at the rear on the 2.25 head) that will need to be removed.

These nuts have to be removed. I think they are marked X in the workshop manual.

thx guys will undo the two remaining bolts and post the culprit for the seized motor - Im no mechanic but guessing the water ingress when i power washed the LR found its way down to the piston and commenced rusting which seized the motor. hoping thats what it is anyway any bets on what could be the cause of this seized motor. will try tonight and give update. thanks again to all responses. cheers

[shamirj]

thanks mate you were absolutely write about the two remaining nuts removed them and the distributor and off it came but still cannot for the life of me turn the motor over. no rust as predicted. not sure what else to look for or try. charging up the battery to see if the starter motor can turn the motor over. any suggestions people tried putting a spanner across the bottom nut and turning but wont budge at all. the soaking liquid on top of the pistons is diesel which has been there for some weeks now hoping to loosen things somewhat

Put it into neutral
