Lack of power further nozzle replacement

[CATS]

I congratulate you on your persistence to get this engine going again.

I have also went through a complete engine rebuild recently after firstly I had the exact same GE failure as yours on the pump and shortly after pump repair burned a hole in piston #1. All pistons replaced with original Mitsu units as I did not need to rebore, only hone. I also replaced radiator and did some bearings and seals on turbo at the same time so hopefully she is good as new. Injectors was replaced with the pump rebuild a few months before. Luckily no overheating ever.

I am always worried about performance enhancing tricks and the resultant engine reliability so steer away from them and keep it as standard as possible. Having said that I have also blocked EGR now with last rebuilt and also removed CAT because I assumed it might be blocked at the high mileage engine already has on. Mine had 300000kms on when packed up but worked hard in its life up to then.

Good luck with your chip and oil additive though, I am too cautious to try on mine.

Hi Cats,

Thank you for your reply.

regarding the GE did you performed its replacement by your self or a diesel repair company has performed the injection pump rebuild?

For the injectors did you replaced the whole injector holder or only the nozzles?
For the piston hole you right the injector is the possible cause.

I noticed that you owned before a Pajero 4th generation, the 3.2 DID in the common rail version how it performing compared to the old one (3rd generation)?

The 4th generation 3.2 DID A/T is equipped with VGS turbo for which there is two models standard power 170 HP (before 2008) and 200 HP (after 2008). which one was yours?

My refurb was done by a diesel specialist. I replaced the whole injector.

I also owned a Gen4 Pajero yes. 2008 model still with the older turbo. It went well but not much better than my Gen3. It was also auto where my gen3 is manual so felt a bit more sluggish. In the end it was not 'different' enough from my Gen3 so sold it again and kept the older one. Maybe I will buy the next propper upgraded Pajero again once they have used up all the face lifts.

Hi CATS,

Good day.

Since I am working with a Mitsubishi Distributor in Tunisa, I confirm that there is no a full model change next year for the Pajero. At least until August 2015.

Few months ago we got from MMC the "Information bulletin" for Pajero 2015 MY available for orders up to August 2015. For the Pajero there is only a face lift + some changes at the spare wheel cover and minor changes at the dashboard level such us chrome inserts, upgraded navigation system...

Hello everybody,

There is some good news

After the Bosch service refusal to perform the defected part replacement because they have not the Covec/VRZ testing machine. I decided to replace the GE: Electric Governor - by myself

I have performed the GE disassembly without removing the injection pump from its location in the engine (but of corse after intake manifold, injection pipes… removal). I have marked the old GE position and installed the new one in approximately the same position

During the new part installation, I left the GE bolts not fully tightened. In fact, I can later move the new GE while the engine running.

After the entire engine parts reassembly I have started the engine. It starts very well but idling at 1000 rpm and after some accelerations it idling at 1500 rpm!

So, with a plastic hammer I tapped the GE from the back to move it, a little bit, forward. Moving it forward decrease fueling and moving it backward increase fueling.

After a second test the engine working quite well. Idling at 750 rpm, no black or white smoke and performing better than before. But not as good as it was before injector nozzles replacement

To finish, I fully tightened the GE bolts and a road test. Every think is OK

So, I succeed to perform the pump repair at home for which Bosch diesel Tunisia declares that is impossible to replace the pump GE without the relative test machines and simply they are not able to repair any Bosch/Zexel VRZ pump . What a shame!

Hello gaaloul.med , my name is Benjamin from Honduras in Central America, your story about you changing your own Governor is great, I have the same problem and I'm also willing to do the same since there is no support in this area of the world. I'm about to buy a new governor from ebay and will take about 3 week to get here. How did your work turned out after your repair?

My best regards,
