Cheers!

Am having fun-usually only get involved with brakes,suspension, minor engine fiddling and electrics. Haven't had a head off for over 30 years and that was an 1800 Sherpa.
Will rope in a few friends when it is ready to put back in.

Cam now out,
One of the lobes is nearly circular-no progile at all.

Not in yet-only getting the head gasket this week (off Autobahnstormers). Hopefully will put the head on next weekend-will rope in 4 friends and rig up a few ropes and poles - 4 to lift and one to guide! Then its just remembering where everything went! (I did take lots of photos). Could have done it in a day and a bit-it took about 4 hours to get out but have been building a car port as shown below.





Got to keep my Royale dry!

Will update with progress!

Nice. Dont forget mate. Anything you need to ask feel free to do so. Be a shame to get it all back together and then realise something should be different. Sorry to ask .feel like im pestering you as well! Did the old cam have a groove ?

Thanks Chris!
Any issues or problems I will be contacting you! Your help has been fantastic and without it I would have missed a few things. I owe you a few beer tokens!

The cam has no groove in it-I believe the additional groove was for pre 1981 cars.

Just a couple of questions!

1-Is the O ring the water feed to the head-it protrudes from the head at the front? (there are also two locating dowels on the block)
2-I've blown out the oil feeds to make sure no blockages-put an airline into the little hole in the tappet enclosure and the air and gunk comes out of the rocker posts. Are there any other oilways to clean?


Many, many thanks again Chris.

Hi. If your original cam has no  no oil groove in its first journal and theres no evidence to suggest that anyone has ever put the wrong one in then thats one issue out of the way.no groove when there should be would result in NO oil feed to any of the head!.so thats ok then.   If you have blown out all the oilways and you can get air coming from all the rocker studs that should be ok too. Yes the pound coin sized rubber o ring is water feed.once all is cleaned up and you are ready to fit head back on make sure the rear 3 bolt cover is leak free.its a bugger to get to afterwards.when you are  ready to put gasket on i usually put a VERY thin smear of silicone gasket sealer down the left and right sides of block and head and the join between engine and timing case.reason.over time with contant heating and cooling,unknown antifreeze history etc etc water can have a tendancy to very slighly seep out of the sides .because of some slight deteriation to the surfaces.whilst not causing any onvious leaks or problems it just looks a bit unsightly .the sealer stops this happening. That what i do anyway. Gasket located on pegs,o ring in,cam in ! Lower head onto pegs.fit head bolts and tighten in sequence all hand tight first then as required. Early bolts with the splined heads are not stretch bolts and can be reused .i beleive the later bolts with allen heads were and need angle tghtening.all my cars use splined bolts and have never had any issues with re using them.they just need retorquing after 500 mile.

Also worth pointing out. Ref the two types of cam hardness. See page 215 of the carlton book. Your cam looks like the softer one by the picture of the follower. If your new one is also the softer one thats fine but keep regular oil changes. Gm improved on this because they wore quickly hence the harder type.if you have the harder type as your replacement.with lug on then you MUST use harder follower too. Like your replacement picture. With the groove near the bottom. Again all shown/ explained in more detail on page 215

Thanks Chris,
Cleaned the head up yesterday-didn't look too bad-this is it before



I used oven cleaner and it came up a treat!

Have arranged for friends to come next Sunday morning to lift it back on and should then quickly have it running (fingers crossed).

Replacing hard to get at hoses and tidying up the wiring in the week as access is now quite good.

It's then on to getting my Royale mot'd.

Thanks again

As promised-valves want a bit of wire wool.



Also started to tidy up the injector wiring as the previous owner had taken the loom apart.

Are you not popping the valves out, cleaning them up and giving them a light lap in?
