been doing a bit of work on an inlet manifold and when i was cleaning it to my shock :shock:i found that the core plug underside had corroded about 2/3 of its dia on the folded edge the only thing keeping the water in was rust and scale deposits.then got to thinking how many owners with a little water in the v might be blaming the pump or man/head gaskets.......... i reckon it would make sense to change it if you have the inlet off for any reason.changed my manifold last summer and never thought to check it now im concerned and my stag sphinctre has started to contract again.
