Hi,

have a long standing problem with possibloe different causes. On the engine bay LHS looking at it from the rear of the van there is a small amount of coolant that collects on the LHS top the engine blokc after under the coolant outlet/inlet on the in et manifold. I replaced the rubber coolant pipe 'J' Shaped but did not sort it and then thought, ohh F*** it must be coming from the water jacket? But the rubber seals on the water jacket look almost new, the engine sems like a recon or even newish VW as it pulls very well and other giveaway signs of newness. So, i put my hand under the manifold middle/ LHS and there fels like an indent of some sort with fluid on / around it. Presumably it could be more than one cause for the small leak but i wondered if in your experience these inlet manifolds for pierburg carbs can and do leak and if so from where?
cheers

under the manifold you'll find two small diameter core plugs one either side of the carb

Thanks Phil, heard a lot about your pug work. Soi, in theory are you suggesting that its possible to repair as opposed to dump and get a goodun? Are these core plugs extractable so that they could be sealed up with plumbers tape or some sort of heat resistant gasket compound or even JB weld?

cheers.

the core plug will be rusted through , as soon as you touch it it might disintegrate just leaving the out edge , this will need removing to fit the new core plug , good motor factors normally have a selection in stock less than a £1 , if you get stuck you could link the rubber pipes together that connect to manifold - OK in summer as should not freeze

Cheers Phil, makes sense. Will have a go. Tim
