I've a couple of probles with my 2.25 engine which has been stood & neglectedfor a long long time. First, when I remove the drain plug unde the exhaust manifold nothing come out. I've poked a piece of wire in and all i get is a black gooey substance - and not much of it. Is it possible for the block to crud up so much internally that this drain hole is blocked off? Second, I got it running and as the temperature came up a core plug at near to the bulk head has started to leak. Any ideas? I was going to dry it all up & rough it up & then try some plasticMetal type goo.
Engine compression is good - can't remember the figures but all within spec. So I think the engine is pretty good apart from the state of the cooling system- I don't want ot remove the engine at this point in time until I've had it running on the road to get a feel for how good it is. And the gearbox too for that matter.
Any suggestions on the drain plug & the core plug?
