Oil leak but can't pinpoint exact location

I have an oil leak on the near side of my engine block. I only noticed it when changing my intake hoses from the turbo to intercooler and intercooler to manifold. It isn't coming from the rocker cover but doesn't appear to be coming from the head gasket either. If anything it looks like it could be from the intake manifold!!!! Is this possible? I did notice when changing the hoses that there was quite a lot of oil in the pipes but nothing too drastic as the engine oil level is fine. I cleaned the block with 'GUNK' but still struggling to locate the leak. Does anyone have any ideas?

Many thanks.

can come from intake manifold ,its under pressure when turbo boosts and oil is allways passed by turbos

Is this anything to worry about? Can this oil leak be stopped? Likewise can the oil passed be stopped at source?
Many thanks.

new gasket ,they often fail

Did you manage to fix this leak? I have a similar oil leak and wondered whether yours was cured with a new inlet manifold gasket?
