So I spoke to my mechanic who's an ex audi tech. He's used Pirtek before and they are good but his concern is that the metal pipes sat behind grill in front of rad provide an element of cooling to the oil with airflow etc to metal, and a hydraulic hose, rubber or similar, will potentially cause issues with such a high performance engine, not giving that extra bit of cooling.
Sounds sensible to me. Any comments?

Pirtek in Oldbury will do an exact match if you ask them. As said before, ask for Aid.
And yes, I can see his point ref the steel. It will help the cooling more than the rubber, but the actual difference it makes might not be enough to worry about.

[quote="MattV8"]Order the parts you need to make up a new flexible hose from torques UK - My DIY thread on repairing one of the other hoses will give you all the dimensions you need as starters. (I've used their kit for everything from oil cooler systems to fuel, brakes, even hydraulics for a powerboat - it's all good stuff). I recommend making it in teflon.

Or - Use a pipe cutter (definately not a hacksaw) to cut the damaged area and splice in a new flexible section with a couple of jubilee clips. Not an elegant solution, but less major surgery which I've done as a "temporary" fix before on a a couple of cars i had. Worked fine.[/quote

thanks to your diy on this i fixed the larger cooler (the M22 size line) line and it worked great. however i now need to do the same to the fitting above (the smaller line) do you happen to know the fitting size of that so i can order the parts?,

I have _815 and _819 solid metal sections from cooler to braided line, the gearbox line has the first section of braided pipe but fortunately / unfortunately it looks like you have this sorted. Sorry, not been here for a while...

I'm afraid not - I've managed to avoid needing to remove/refurb that one.
