Possible leak or split on a boost hose coupling or crack on intercooler.

Leaking exhaust. Manifold to turbo, or turbo to downpipe

When a car tailgates me, i slow down - then floor it and give them a cloud of diesel smoke to choke on :driving:

Ok thanks for the help guys car belongs to my brother in law trying to give him a hand while I'm at the coast ...on holiday at the moment will check it up next week and give feedback... what if it's not the intercooler ,manifold or boost pipes ? Boost pipes look ok will need to pull out the intercooler and send for boost test
