Hi all,
Just thought i might give an update from my post id: 33801. Turned out that the "EGR valve connecting pipe" ( as per listed from my Gregory manual ). Where it flanges on to the bottom end of the EGR valve had warped and also cracked the metal gasket, so i was losing exhaust and it was creating the high pitched noise through the gap. I must say i was lucky enough to be given a number of a mechanic that works for nissan & does a little on the side on his days off. Aside from hearing of plenty of stories of common problems regarding all the new & older patrols that he has to fix, it turns out that he has to repair these pipes almost on a daily basis. The problem is that they are made of alloy & just continue to warp. So to repair this time was to file the warp out ( which was pretty bad ), then simply replace the gaskets at either end. I was very fortunate to have been put onto this guy as it only cost me $50 & that included the gaskets which was the grand ole sum of $15.30. I dunno if i will end up keeping the patrol long term or not as even though this is the first problem i have had ( touch wood ), after hearing some of the stories of what goes in & out of nissan its all about luck of the draw. And although the better half and i were originally seeking a 4.2 TD landy it all came down to about the 8-10 grand price difference. However if i do decide to go the longer term option of keeping it i think i'll be having a go at making my own pipe from exhaust pipe with the same where it plates on.......as at around 300 bucks a pop for a replacement pipe, he all but guaranteed me that it will warp again & again.

Good luck to all those other Patrol owners out there & thanks for the feedback that i recieved when i had the problem !!!!!

Cheers
Dan
