In the ever so ongoing list of maintenance required for the old boy, the current Intercooler hose has gotten quite maliable and near the intercooler, quite oily.

The fact I can quite easily squeeze the hose doesn’t bode well for when it’s under any boost pressure, I’m assuming it’ll be expanding slightly robbing me of precious ponies.

On the back of this I’m a bit concerned about the hose attached to the intercooler being oily. I know there’ll always be some in there as it naturally will seep a bit past the seals of the turbo. What’s confusing me though is the hose from the turbo to the first metal elbow before the intercooler is bone dry. Could it just be settling at the intercooler and pooling there? When I did the glow plugs I checked the intake manifold and no large deposits of oil in there.

Finally, Intercooler hose. I can pay £140 on fleabay for some silicone, £100+ for some LR stuff, OR I can spend maybe about £40 on some Britpart stuff - I’ve had no issues with the Britpart items I already own anyway. What’s it worth going for?

The intercooler/turbo hoses are quite soft and yes the oil does collect in the intercooler. Personally I would be happy with Britpart for hoses.
 
Thank you, saved me a few £££. What would you suggest cleaning the intercooler out with? I’ve got a Jerry can of diesel left over from when I filled the fuel filter on the last service if that would work?

I use Acetone but make sure it's all out and thoroughly dry before refitting or the engine will rev it's nuts off. Acetone works better for cleaning and evaporates quicker.
 
I used petrol to swill it out. Acetone is betterer. Plug the ends with rags and once you’ve let it soak I put one end of intercooler in a bucket and poured the petrol through again and again. Any leaks on the fins will show up after a soak and suprised how much black continued to come out. made a significant difference to power.

Diesel will be fine. I used petrol last time and then left it in the sun to dry.
 
Diesel is dangerous as it takes for ever to evaporate which can lead to a nasty engine runaway.

As long as most of it is out it will be OK. Diesel seems to be way more volatile these days, possibly the ethanol or biodiesel content. Either way, it isn't like the waxy stuff of old. Petrol or acetone definitely better though, especially for the final rinse.
