intercooler pipe

Hi what would cause intercooler pipe on inlet side to collapse????
took off to get back to uk.

Blocked intercooler, delaminated hoses, blocked air filter for starters.

Wouldn't blocked intercooler only cause it to collapse on outlet side? Or do I have my inlet/outlet definitions wrong?

Thanks for the replies but turbo blown in Belgium, oil all over place on n/s of engine bay were i removed inter cooler pipe.Waiting for recovery to UK good job got warrenty on it.

Path of air is into air filter, across engine in rigid plastic pipe, into turbo, out of turbo through a selection of metal and rubber pipes to intercooler, out of intercooler through more rubber pipes to manifold. If the engine is trying to suck in air, a restriction at any point can cause the pipes to collapse. A turbo running in a vacuum does nothing

When the hoses are old, then they become soft and then they collapase (especially when hot)
Has happened to me several times.
