Recommend a replacement intercooler?

At 220000 miles my 2000 TD5 CSW has a 'spray' of oil on the rad grille in front of the intercooler........seems likely to be a pin hole leak? Seems generally a bit short of turbo grunt of late so need to rule out lost pressure here and work backwards to the turbo eventually I suspect.

So, you very experienced types out there - is there an obvious good candidate for a replacement intercooler? No tuning involved so I'm looking at a straight swap out and in, unless there are good reasons to do anything more sophisticated while I've got it apart? I'll replace the pipes anyway.

Hope you can help with good ideas/previous experience/recommendations - thanks a lot. A

There's a new TD5 OE one on ebay for £85.
From a reputable LR parts seller by the look of it as well.
Item number is 331698032977

I asked the company who rebuilt my engine the same question and they swear by the 155mm core ones on eBay for £155, they use them all the time and never had a problem with any so that's what I've got, just haven't got everything back together yet. They also advised fitting an egt gauge too if the fuel pump is to be adjusted.

Thanks chaps - a good start.... Cheers A
