WK diesel failures in NZ!

[bjm]

I spent an hour with an independant Jeep mechanic yesterday out of Christchurch
NZ.Very busy as a major Jeep dealer got rid of the franchise a few months ago.Sounds familiar.! He is a long time Jeep guy both himself and his wife drive 2016 WK diesels.He got his really cheap due to a knock in the motor.He rebuilt the motor but said parts are a major problem !However he is now onto a operation in the US who is getting forged cranks and updated bearing kits made.Good second hand motors now fetching around fouteen grand retail.! He has fitted a 2011 motor into 2016 with no problems.Been using 5w40 Penrite Enviro in the workshop and his vehicle for last five years,plus been adding Penrite zinc additive in his with no problems,go figure.!He said he has seen no change in DPF burns temps,etc over the last five years.
So I thought I would put a half bottle in mine ! He is Now using the 10w40 Penrite Enviro.in all the Jeep WKs he services.The valley coolant hose failures are increasing just like in Australia.Not many oil cooler failures.
Reckons Jeep are stuffed as a brand in NZ without the diesel Grand Cherokee.
I might add that this time in NZ the number of WK diesels towing Aussie vans was way up on previous years!Mostly Jaycos.

Interesting comments bjm...

Very good to read that some one is taking an interest in the VM diesel and rebuilding them.
Personally I would like some one to take an interest in the oiling system on them, and maybe take a good look at giving them a bit more oil pressure at low rpm.

Is that the Penrite Enviro+ 10w 40 HD he is using?

I'd love to have the space to keep my old 2014 and pull the engine on that and rebuild it, it was running fine when I turned it off for the last time, albeit with a noise in it.

Sounds like I followed his oil regime as well ............

I can concur with seeing more jeep gc diesels towing than ever .
Just being towing our caravan down the southwest WA and saw heaps of gc in tge caravan parks .
Went out to the Yagerup sand dunes one day down near Pemberton, brutal track out to the coast.
Heap of cars getting bogged , saw a Wk2 gc power through it.
A heck of a good car.
Even the brother inlaw with his Toyota 200 series reckons the jeep gc is way more comfortable to drive.
The reason why there are some so many out there now is where are you going to get a 4x4 that can tow most anything, drive up sand dunes effortlessly and be comfortable at a bargain price!!
Pity Jeep as a company have currently lost their way!!
