Another <span class="highlight">grenade</span> explodes

Were you towing Ronnie and what was the outside temp. Was the vehicle going up a gradient?

Cheers Mick

I really feel for you. Been there, done that with a 2005 GUIV. Blimey! 650 degrees. I thought 550 was pushing it. I always changed down a gear (auto - take out of O/D) to bring the revs up and eased off until back under 500.

Nissan said no to rebuilding mine but I kept pushing them. In the end they repaid me for the 3rd party engine rebuild kit. I rebuilt the motor myself. The engine has to be removed from the vehicle. If you need any further advice just PM me.

Darn (to paraphrase in a printable manner) - sorry to hear that Ronnie. What was the boost showing, and what did it normal travel on?

My condolences.

Had to do an engine rebuild on the pajero last year too, when I thought every was going well.

Hope you won't cost you the full amount of the rebuild.

G'day Ronnie, sorry to read of your dramas.

I am wondering whether you had done any other alterations to the engine....EG: had you blocked off the EGR valve and had you fitted an oil catch can on the PCV valve? These are 2 other things that have often been mentioned on the Patrol4x4.com.au forum.

There is a wealth of knowledge on that forum (if you can get past all the petty back-biting that certain 3 litre owners go on with....they refuse to believe that thier beloved 3 litre motor is anymore prone to hassles than other motors).

As for your idea of converting to a Chev 6.5 V8 diesel....... as the owner of one of these rigs, may I just say this..... Whilst I am very happy with my rig, it is certainly not the be-all and end-all of the options you have available to you. I could never have justified (to either myself or my wife) the cost of converting my 2000 4.2TD GU (which was and still is running perfectly well), over to a 6.5 V8. But, like the big kid that I am, I always wanted one ever since I heard one rumble past me several years ago. So, when one came up on ebay (of all places!!!), for an effective changeover price of $15K AND it had been converted to a dual cab; well I couldn't resist.

However, if I was in your predicament, I would seriously be considering following the path that has been blazed by Member Colin and his "Project TONI"..... as in TOyota and NIssan combined. There is a good write-up on this forum (search is your friend). He fitted a Toyota 1HD-FTE (I think that's the code) 4.2TDi engine into his blown 3 litre Patrol and he couldn't be happier. I reckon he'd have more power than my 6.5 (which is naturally aspirated) and probably just about the same amount of torque. BUT, his fuel economy is probably quite a lot better than mine (I use about 17L/100) and parts would be easier to get.

Good luck...... I wouldn't waste too much time chasing Nissan for the blown engine; they are a total waste of space!!!

Cheers

You said a max of 14psi and towing, you melted it pure and simple in my opinion.

When these mods are done the limits are held to around 16-18psi and 550C.

As far as I was aware the accepted design EGT for these engines is 600C post turbo.

As for Nissan supplying a new motor, youve got to be kidding, 9 years old and heavily modded......

Looks like Nissan coming to the party and supply rebuild kit ,have to see local dealer service manager tomorrow to see where I go from here.
Cheers Ronnie

I was reliably told that the difference between after and before turbo temps is about 200deg.

Never run mine over 500deg and the sensor is in the side of the dump pipe

about 4 ins below turbo in a 100ser

As long as you didnt alter the lead from the sensor to the gauge it should read correctly.

If you did it could alter it dramatically.
