Ok, I'm about to start doing a head gasket replacement on my TP Magna (carby) sedan. I've read Magna Buff's info thread and also the Haynes and Gregory's repair manuals but I still have a couple of questions. Any advice would be appreciated:

(1) Will I need to remove the carby to get at the inlet manifold bolts or can the whole shebang be unbolted as one?

(2) Is it really necessary to unbolt the rocker assemblies and camshaft? From the pictures, it looks as if you can get to all the head bolts with them in place so, after removing the water pump pulley and removing and securing the camshaft drive sprocket, is there any reason why one can't unbolt and remove the head with the camshaft and rocker assemblies still attached? The Gregory's manual seems to indicate that you can but it is a bit ambiguous.

So many things can go wrong that I'm trying to eliminate any unnecessary steps. I could be wrong but I don't expect any work to be necessary on the head other than replacing the gasket. There appears to be just a simple head gasket leak at the rear of the engine below the waterpump pulley. No water in the oil, no oil or gas bubbles in the water. Engine still runs smoothly, so the water doesn't seem to be getting into the cylinders, just leaks from the water jacket to the outside when the engine is running and hot. When the engine cools, air is then sucked back into the cooling system.

efi or carby
both can be taken off with the head on
just unhook the fuel line and wiring
to undo at the studs
its a bit tight on the drivers side
I use a 12 mm spanner open ended short length

or a small socket and rachet if there is eneough room

you can lift the head off
its just efi has a stay bracket underneat the inlet manifold
you have to undo it from underneath at the interim shaft

1 leave the inlet manifold on the head till its out there is a 18mm bolt under the manifold you have to undo, you need to get under the car to get it.
2 you can leave the cam and rocker arm coneted . just undo cam gear make shore you have the timing at tdc to make shore you have the timing at tdc . will make it easier when reassembling

Thanks guys, that's good to know. Yes, I will be very careful with the timing. I'll mark the distributor and the also the timing chain to ensure it all goes back exactly as it was before. I'm probably going to start this on Friday, depending on the weather. Will let you know how it goes. Thanks again!
