It is easy enough to check the turbo manifold for leaks by removing the heat shield and having a look for any soot deposits.
 Click image to enlarge Click image to enlarge Click image to enlarge Click image to enlarge I used a boroscope to check the bottom of the turbo flange for leaks. I have had two leaks from the intercooler hoses over the past 4 years and a bit of investigation found the problem Below is the intercooler pipe going into the inlet manifold and at first glance it looks ok? Click image to enlarge Click image to enlarge But once I separated the pipes the cause of my issue became clear, it had delaminated and there was a rip that only became visible when the hose was pinched. So under boost pressure the hose expansion was enough to cause the rip to vent. Cured this by fitting SS steel intercooler pipes : Click image to enlarge Click image to enlarge Click image to enlarge The second time was due to the boost pipe being loose on the turbo: Click image to enlarge Click image to enlarge There is also a service bulletin ref a plastic stud on the inner face of the wheel arch line that over time holes the nearby intercooler pipe: Click image to enlarge Also check that your actual inter cooler has not failed, cracked etc. HTH :thumbsup: Admin note: this post has had its images recovered from a money grabbing photo hosting site and reinstated  |

that's worth looking into, theres a coolant hose to next the fuel bleeder that chaffs two. Top right hand side of engine bay as you look at the engine, covered mine up with a bit of old heater hose and secured the bleeder just in case.

Problem found .. The bolt on the steering shaft has put a dirty great hole in the intercooler pipe.

Possibly not though there will be increased risk of particles entering your engine as it is on the "clean" side of the air filter.
Might be worth wrapping it with some cloth tape to seal it temporarily until you can fit a new one. |

If you run with the holed pipe you may find that you'll drop into limp mode with the MIL illuminated due to boost problems. A very short term fix can be achieved with duct tape, but the heat tends to make it unstuck. A better temp fix is to cut the damaged piece out and replace with a short metal pipe, or wrap a cut up drink can round the hole and secure with a hose clip.

Problem solved thanks to the nice folk at Town and Country Land Rovers in Leamington. Dropped it off this morning with no notice and it was sorted by the time I finished work .. they even fitted my new Allisport intercooler

self amalgamating tape here would work too for a repair, obviously not now needed but added in case others have issues. Cheers
