We need to see what it looks like, and where it is. Sounds like a head gasket issue since yellow usually points to that.
I took a shot in the dark to put an answer out, but I aimed in the direction with the best chances.

You can get a head gasket tester that can check if it has carbon monoxide in the cooling system to verify. You can also see if you have a cylinder missing which can tell you which cylinder has the leak.

@barriphone It's almost certainly the head gaskets and other seals. Classic Nissan defect post Renault. Individual testing is redundant - even one leaking is still a leak.
The only individual test worth *doing* is a cylinder pressure test.

It will probably have a cylinder misfire code in it and what cylinder it is.
