Yes turning the cam is no problem once sprocket is off and all followers are out. Note the cam will also move backwards if you let it as its the sprocket and plastic centre screw that keeps it in line. Are you going to have the head converted to unleaded or just use an additive or just use it 'as is'.The valve seats are cut straight into the head material without an insert on the early ones hence the later unleaded inserts.if you grind the valves in you lose whet they call 'lead memory,a fine lead coating from previous leaded petrol'.the head material is of good quality and should run for a while bare but many beleive valve seat erosion eventually happens.

I think I'll use it "as is"-and add a bit of additive now and again.

Many thanks yet again

No problem anything you need to know feel free to ask.Still learning the omegas ways and means but the old cav/ carlton cam in head engines ive done a plenty. I have my way and order of doin things as im sure everyone has.nothing too peculiar about these engines.i find them easy enough to work on.non interference between pistons and valves.everything easy enough to get to .when you eventually lift the head have someone help you,lift it vertically to clear the cam sprocket and watch you dont loose the small o ring near the front of head down the gap by the timing chain.it usually stays stuck to the head! . Cheers.chris

Hello all,
Had a bit of time tonight so started to strip down the engine. Took all the rockers off and tappets out. There were another three tappets starting to wear. Will disconnect the exhaust and detach all the injector wiring next.
Have to fit it in with putting a roof on the carport.

Had a few hours today on the car. Everything apart from the throttle cable and servo hose disconnected. Head bolts nearest the screen bstards to get at due to the air con pipes-think I'll bin them.

Fun will now start when I try to loosen the head and actually move it to the bench.

Never found the cam-in-head heads ever gave much of a fight to removal, can remember lifting the front end of an Avenger up via the cylinder head once trying to split one of those. 

[Steve Brookman]

Thanks Mark-it did release easily after I remembered to take out the two bolts at the front which go through to the timing cover!

Nearly killed me lifting it out though and putting it onto the bench!



You can see it on the bench behind. Will have to get a few mates to help me position it back in.

Just figuring out now how the camshaft comes out-I think it just pulls forwards-will have to ask cam-in-head (Chris) on here.

Most serious mechanicing I've done in a while!

Cheers

Seem to remember they come out the back...............or was that on summat else?

[cam.in.head]

So long as all the head bolts are out it slides out of the front. Each cam bearing is slightly bigger than the next one so it will only come out frontways.did you recover the front o ring from head gasket ok ? .yeah they are a heavy head and two people to lower it back on is a good idea.  Once its out see if the front cam journal has the oil groove.if it has make sure the new cam has.if it hasnt it can be machined in. Any more info feel free to ask. Cheers .

[Steve Brookman]

Thanks Chris- forgot to look for the o ring-I just placed the head on the bench and left it. Will check tomorrow. Will try levering the cam out as well.
Many thanks yet again

Steve

It wont need levering. Should just slide gently out .do it slowly and carefully to avoid scratching the bearings in the head with whats left of the cam lobes.

[Steve Brookman]

Thanks Chris,
Can I take the back plate off and push it out?

Steve

[cam.in.head]

Yes if you need to but you shoud just be able to reach into the head an touch the back of it without.. following all this with interest mate. Keep up the good work .chris

[Steve Brookman]

Thanks Chris!

There is also a remoeable plate on the side of the head just above the spark plugs.a new gasket for this will be in your head set so might as well remove it.it makes it even easier to get your fingers in to guide the cam out. Just read your pm .those big things in the head you are referring to are not meant to be removed .i think they are just oil gallery plugs
