Diesle Injector service

Hi Ian thanx for the advice and I will check out those sites just for some additional info I had a bung in the top edge of the dump pipe so I removed it only to find it was to big for the sender to screw into so I used the supplied weld on nut and insted of drilling a new hole I welded it ontop of the hole the bung came off as this was in a good reachable location and then I wired the VDO gauge up so do you think this is OK ? or have I stuffed up ?

Regards John.

Hi John,

Sounds like your dump pipe came with a metric 18mm threaded port (DTS/MTQ use this size port, never been sure about Safari). [Just by the way, I can supply a brass adapter (reducing bush) to go from M18x1.5 male thread to 1/4" BSP female.]

As long as the VDO sensor (thermocouple) is projecting about 15 to 20 mm beyond the inside of the dump pipe wall, it should be reading quite OK. If it's less than 10mm, I'd be a bit concerned and would try to get it in a little further. Hope this helps.

Hello ...? mate I boughjt the 4B with the kit fitted but I think your right I dont have a modified pump and that is something I will look at in the near future could I ask if you are a local to western SYD and if so who do you like to use for the work you mentioned ??

Regards John.

Hi John!
I do not understand why system does not show my nic (KSV). I am living in Melbourne and thus know nothing who is good in Sydney. I got 80 1HZ with DTS aftermarket turbo WITHOUT compensator. As I said in previous post I did everything by myself - took of pump and injectors and gave them to big "diesel fuel system only" factory to service/recalibrate. They fit compensator at this time. And I fit everything into car by myself. After fitting compensator I have not notice any difference in fuel consumption, either positive or negative. However I rid of ugly black smoke and my truck became more responsive.
Cheers

Hi KSV , mate was the pump hard to remove and did you have to use any custom tools or know anything odd as I thought that if I removed it It effected the timing or somthing (hey I dont know diesles ) so how hard and how long did it take ?? and from what I have heard the DTS is better than my safari (garrett) and what boost are you running .

Regards John.

It is cumbersome, but not difficult. Only special tool you need is universal pulley remover. You cannot stick pump back in “wrong way” because it has key to prevent this. Also it is advisable to make marks on pump and engine to install it exactly in the same position. However if pump will be readjusted it may skew timing a bit. Timing is easy enough to alter on engine, so I fail to see much issue here. I done everything first time and it took me less then half a day (i.e. removing timing belt, injectors, pump and camshaft for valve clearance adjusting). If you decide to do it, then it would be an excellent time do above mention stuff as well. Particularly valve clearance – it is extremely difficult to get spacer out even with special tool – forget about “two screwdrivers method” recommended by some SM, it is sure way to squash your fingers. Only one thing almost impossible to put back by your own is timing belt tension spring – and you need someone to help you (girlfriend/wife is OK, she can put spring in position while you pull it). Also you can study Gregory or any other SM.
Good luck.

PS. Also if you will take camshaft off, I would *STRONGLY* recommend to cover all oil path from top of engine head with dump cloth upfront – bolts very oily and it is incredibly easy to drop one inside engine.

Thanx Dave I was hoping to get positive feedback I will try them and if there good I will definetly sing their praises .....But if there bad .....?? Lets not go there as they seem like real good blokes that dont talk Rubbishwell that the vibe I got anyway. :)

regards John.
