Isuzu 4JX1 Injection System Manual
INJECTORS, O-RINGS AND STRANGE LEAKS.
This article is based on my own subject research, personal experience from dismantling a
set of injectors in my shed after they had failed on a work mate’s car and invaluable
advice from a very knowledgeable and helpful overseas source who works on these
engines on a daily basis (thanks !) I hope this information will in some way help owners of
vehicles fitted with 4JX1 3.0 TDI engines, who may be faced with strange symptoms such
as rising sump oil level, diesel in coolant circuit, etc. to diagnose the source of their
problems.
I do not profess to have a detailed knowledge of all aspects myself - I am an enthusiastic
amateur rather than an automotive professional. Furthermore, I accept no responsibility
for what readers choose to do with this information.
