Hi all, its my first post and yes i am also a pom but lets get those matters behind us....
I have to say a huge thanks for all this relevant info and experience that is shared, i have to agree its easier to use this site than talk to the local isuzu dealer!
Anyway, i bought a 2003 Trooper with the 4JX1 engine from my local Isuzu garage here in the Philippines (its where i live now) back in January this year. Car had just over 250,000 Kms on it but with a full Isuzu service history, drives like a dream and has been 100% reliable. Its a local car, (most are imported and converted to LHD), so all the wiring is original.
First question is regarding the 4JX1 engine installed in the trooper, is this the same 3.0 4Jx1 that is installed in your Jackaroo version and therefore can i use the great technical details that are posted under the Jackaroo/4JX1 technical thread? i can post the engine numbers if this helps.
My car drives perfect but has always had some black smoke from the exhaust under acceleration, once cruising it is not noticeable, i did not think to much of this as most cars here in the PHP smoke and the emissions standards are a little different to most places in the world and the local diesel can be a bit rough...
When i took the car in for the annual test this year it got a 8/10 for the emissions test (10 is a fail) both the garage (Government controlled) that did the test and the gagrage they referred me to (private owned) told me this was due to the turbo not working. I did not agree with this and took the car home, pulled off the intake pipes and could clearly see the turbo operates as expected and has no noticeable play on the shaft. Sometimes they just see a big dumb dollar sign walking in the door....
I took the car to the local Isuzu garage and was told i would have to replace all four injectors, they did not even come outside to look at it!
Has anyone posted a logical checklist of issues that i could run through to see what can be done to isolate the cause of this smoke and then look into a fix, other local mechanics all immediately say its the injectors but again i am not convinced as i dont seem to have any of the syptoms of changing fluid levels, diesel in coolant etc that are extensively reported on the relevant threads. The trooper was not a really popular car here as its was expensive when compared to local products so a lot of mechanics have very little exposure to them.
After reading the great thread on injector and sleeve replacement i was thinking of pulling it all out, cleaning/ checking and rebuilding with new seals/gaskets to the procedures in the thread but dont want to cause further problems if this could be another simple fix.
I am an aircraft engineer by trade so not afraid to get into the engine but have no diesel engine experience as we dont use many in aviation!
I did replace all the glo plugs last month as the car was slow to start, three were shorted out, and this cleared up that problem. Like i said it runs great and you dont always open something up unless you really have to....
Any logical checks greatly appreciated.
Best regards to all.
