Testing for exhaust manifold leak 120-130 1967

Hi,

My car has a B18 with twin SUs and a Simons 4 branch manifold. The manifold is about 14 years old, the car is always garaged and has only covered around 1500 miles since the manifold was fitted.

I'm constantly getting exhaust fumes in the car and noticed recently when I started it that there was exhaust smoke in the engine bay around the manifold. All the mounting nuts are tight but I can't say where exactly the fumes were coming from. Subsequent startups have been less smoky so it hasn't been possible to identify the source.

I'm guessing that the three main culprits are either the manifold gasket, the manifold itself (they aren't very substantial and its possible that its rusted through somewhere or a weld has failed) or the gasket between the manifold and downpipe.

Can anyone suggest a quick way of narrowing down the leak?

Thanks in anticipation,

Aidan
