I have a slight constant drip of coolant from the underside of the inlet manifold. It appears to be coming from the area that part 19 shows on the underside on the attached diagram.

Two questions: What is actually on the underside where this cover (Plate?) is ?

Is it easy to remove and fix or replace the manifold.

its more likley to be the pipe leaking and runnning down under i suspect

19 is a core plug and they can rust and leak but as said ^^^check it's not just running down from the pipe at the rear right next to it, often the aluminium corrodes and forms white Aluminium oxide under the pipe and then leaks.

Thanks for the comments, I had a pretty good look at the leak and it wasn't from the pipe so corroded core plug could be the problem. Are they available as spares?

Cheers

yes core plugs are standard not specifically VW I'm guessing 24mm as it has 24 in comments but need to measure it.
Somebody borrowed my spare maifold so I can't measure for you, maybe somebody else can as I doubt you can measure in situ.

Itchy, Many thanks for that, yes pretty impossible to measure in situ so if anyone can help it would be much appreciated.

Ians link to Brickwerks says it's for inlet manufold so deffo 24mm then

Thanks folks, good result.

Will need to get gasket set.

Any tips when extracting manifold bolts, they've been in there since 1987 !

Never had a problem getting bolts out.
Make sure gaskets ate fitted the right way they are not quite symmetrical

Personaly I'd use some dirco S or equivilant on the plug

Best advice for undoing any steel bolt into aluminium, get it warmed up , run the engine up to temp , then crack them quarter of a turn and go get a coffee and let the engine bay cool before continuing with the job .

The inlet gaskets are all you need and they are available individually.

Will I need to replace the carb gasket ? Or does that stay on the manifold when it is being removed ?

Cheers

no need to remove the carb from the manifold .so no need fpor gasket

it's not good to turn a carb upside down, any dirt in the float chamber can clog jets.

Personally I would remove carb and keep it upright, you can't buy the lower gasket so need gasket paper and make one.
