Hi
I have a problem with revving above 3000 and searches suggest it could be related to hoses collapsing? Would this be visible when stationary or does the engine need to be loaded?
Cheers

What engine do you have

If a boost pipe take off and look for splits

Td4

Remove your incooler homes and look for splits... sometimes you might get extra smoke when a pipe has split

I was going to do that as well but was interested to know if the collapsing pipe issue was easily checked.

they will look a bit flatter than usual get someone to rev your engine a bit and look at the hoses and they will expand but better still get the DPH silicon hoses ,I know they are a bit of expense but they are good and do not expand as such there for your turbo does a better jobby

For the price of some standard hoses, change them. If the faults still there you have a problem.
Agree with teddywood1, if you can afford them, go for silicone hoses. In the long run they are cheaper as they outlast the cheap rubber ones.

A mate of mine had a problem with the inner part of one of the boost hoses detaching & collapsing inwards, this was not visible from the outside as the casing kept its shape, I'm pretty sure it was a silicon hose also.
Seems that there are many TD4's with the same problem at the moment, difficulty revving past 3,000 & low power above 50 mph, I know of at least 3 freelanders having this problem right now including mine & from trolling this forum it seems to be an epidemic

A hose that has collapsed is pretty hard to spot without removing it. The whole hose can't collapse because it's pressurised. The collapsed section is usually inside the hose, where the inner layer has delaminated, blocking the air way. The intercooler can fill with oil and other debris too.

Going to replace with standard hoses, as I am not sure how much longer we shall be keeping this one - done 150k so far.
Any advice on how to get to the clip at the bottom of the intercooler hose? Do you need to do from underneath or remove the front "bumper" - or does it just need a small child with double joints?

We tend to just change the 3 top hoses from intercooler through to EGR pipe.....
