Rocker cover removal

Hi Bret
The coolant colours made me say reddish or brown if a bit old or the system was not clear of corrosion.
When not working on it the bonnet has always been on, we have had one or two heavy rain episodes but no way i can see for how it would get in.

Hot days and cold nights plus heavy rain means a LOT of moisture, just look at how damp your windscreen is on these cold mornings, that moisture gets everywhere.

Yes it was, that would be a lot of condensation - about 3 tablespoons? If that's all people think it might be then I'll stop panicking and go back to the reassembly (fingers crossed).

If it was a head gasket the water would have mixed with the oil and all of the oil in the rocker box would be grey and milky, it would definitely not result in a pool of grey water !!
So relax !!!

Just looking at the 2 mating surfaces and there is no obvious sign of old sealant, it must have been a hairline bead! Absolutely nothing that can be pulled away and I'm using a thin flat craft blade to go over it, carefully of course.
And the diagram is not easy either to see where it all should go, so hoping for the best.

Went to refit and it wouldn't lay flat, took it all off and checked for true worrying that it's time spent hanging loose had warped it, but all was good.
Think i'm correct in thinking that the rocking/high point is actually one of the valve rocker assemblies in the open position.
Should i then just work round securing the screws down in order and it will all fall into place?

There will be valves that are open and so when you replace the cover these will have to be compressed by the cover to depress the spring pressure and the valve.
If you have lined everything up correctly then you can gradually tighten the bolts in an even and slow manner, try to keep every bolt evenly screwed in and gradually go around them all bit by bit drawing the cover down.
But if you haven't lined everything up correctly (the timing marks etc.) then you might run the risk of depressing a valve into one of the pistons that are at or near top dead centre.
But do try to find specific instructions on the reassembly, trial and error can be costly.

Job done and so far it's a good'un!
Thanks to all your encouragement and knowledge I have restored the gasket and replaced the housing and completed my first timing belt replacement.
It sailed through the emissions test and has been rewarded with a new MOT.
A great learning curve and very pleased with myself, the car is so much quieter now it's firing on all 4 and pulls a damn sight better. It has a slight squeak but hopefully that's all the new parts settling down.
I did have a near miss though. My first attempt to apply the gasket had me awake in the early hours as I was sure the sealant was going to get into the oil ways. Once it was light enough I had the housing off and sure enough the oil channel holes were filled with sealant. That was due to the best diagrams being too small and vague, a chat with a friendly Skoda dealer gave me the correct procedure.
