would a reduction of turbo boost on the grenade nissan 3ltr stop the implodeing

G/Day Robin

I had a problem recently with our 2008 Patrol, with a High Pitch Whistle comming from behind the FireWall, it would happen under load, I made mention of this on the EO forum, a few members gave me some advice ect, some said it was the EGR Valve playing up or the EGR gaskets leaking, anyway seeing that the vehicle was under warranty I took it to the dealership from where we purchased it from, they had no idea what was causing the problem, I mentioned the EGR Valve and they said nah we checked that, it seems ok, anyway I had it back there 4 times with no result, I then phoned the Nissan head office in Brisbane, and they told me that it was the EGR Valve, and had the vehicle booked in for repairs at another dealership, they fixed the problem straight away, it was the EGR Gaskets, Nissans head office stated that some dealerships don't bother contacting their technical section for advice and give the customers the wrong info and some times cause more damage.

Cheers

Hi Daza

Thats the approach , you are probably very happy you persisted now - I'm sure some of the bad ones are because others just didn't have time/knowledge to keep pushing.

hi daza
smart move be persistant and if the dealer fobs you off do like i did also
i rang the head office in the eastern states for my mazda problem
a few years back and got positive results

the head service man came from melbourne to bunbury after lodging a written and detailed complaint it was fixed under warranty

and the dealer was advised if he didnt lift his game they would take the dealership off him
never take no from a dealer they are only a part of the system in the motor industry
contact head office and get to the top man in the service department
my daughter had trouble early this year with a mmal dealer in perth who fobbed her off

so i told her to contact the head man in mitshu h/quarters and she wrote a details complaint
he came to wa and checked out her gearbox problem drove it around for a short period and came back and said it had a problem

a new $8000 gearbox was fitted within 14 days as it had to come from japan

the dealer claimed the original was not faulty and was refusing to do anything except kept saying it's covered by warranty if it fails

ignor the rebuffs by the understudies and go to the top brass this has always been a winner for me

Unfortunately they don't have 4.2 diesel autos, unless your talking petrol.

hahahaha...Bigger sump????!!!! No, they took the easy way out (as usual) and provided a shorter dipstick!!!

hi everyone
thanks to you all for the answers and explanations

much appreciated and i did know that the amount of fuel has to be adjusted if the boost is reduced or altered together with other adjustments

and i might add i was not contemplating buying one
but thought after the quote by toni in
toni project blog

that there may have been a simpler solution to this destructive and lengthy problem

i realize the best fix by nissan would be a new beaut motor but where /when will that ever happen
waiting for nissan is like waiting for a drought to break????
cheers and thanks
