advancing JX diesel injector timing
Posted: 08 Oct 2019, 01:50
My JX engine was the sweetest runner I have known.
I had my cylinder head replaced because of a crack ( JX cylinder heads are only good for about 150k miles).
I had new (reconditioned) injectors & new glow plugs.
The mechanic told me that the injection timing was not standard & that it had now been reset to ‘factory settings’.
Since then it has been underpowered & I have to use the cold start injector advance all the time ( I never had to use this until -10C with the old head).
It’s much slower to start from cold with what sounds like running on 3 cylinders until reving the engine to get it going (more white smoke than before).
Once under load she runs normally with no smoke
I have now checked the valve timing, injection pump timing (it is factory at 0.9mm)
Having done some homework I am wondering if I need to advance the injection timing or if the injectors need testing.
I am now living in Canada where winter starting can be below -30C.
I have fitted an engine block heater & this makes starting much better but still underpowered (&yes I have tested the glow plugs)
If you have had any experience of advancing injector timing I would appreciate your advice.
