i am new to this forum and i have a question on Calibration. i have a 1999 fieldmaster with over 200,000kms with no overhaul so far. i have hard starts in the morning but when i get it running its back to normal. a mechanic said it needs to be recalibrated. (or change the glow plugs)
i read somehwere that diesel engines need to be recalibrated every 120,000kms. so what is the correct approach?

hello dieseldude!

planning to replace the injection pump drive seal dahil may tagas sa likod ng timing gear case. wala nako makitang source ng tagas kundi sa injection pump lang.

isuzu 4JA1 naturally aspirated. not sure kung zexel or bosch...

tanong ko lang kung kelangan pa rin bang icheck ang injector timing (plunger stroke vs. crankshaft rotation)?

or simpleng salpak lang pupwede na?

kung kelangan e di may rason na akong bumili ng dial indicator kung ganun.

i have no issues so far naman with regards to excessive exhaust smoke, acceleration, etc.

2004 dmax MT 4jh1. Starter cranks strong but engine wont start. Handbrake light lit even with parking brake disengaged. Battery light also lit at key on position. Is the lights some sort of code to identify the problem. Car died on the road while traveling about 40kph.

Mga Sir, ask ko lang kung ilan odometer reading kailangan magpalit ng nozzle tips ng 3L na engine.

After 6 years lol.. got my clutch / pressure covet/ release bearing replace at 278000 km. Aisin for the clutch and Nachi for the release bearing. Ok na ok ang performance. Lumambot din yung clutch pedal. For FC , the mechanic in toyozu suggested na ipacheck nozzle tips sa 300000. If yung spray pattern and leak test hindi na mahabol.. time to get ORIGINAL nozzles na. Sabay na rin papalit sa timing belt

sir dieseldude,

Quick Question lang.

ano ba size ng oil seal (front) nung injection pump ng isuzu 4ja1 NA???

ang nakikita ko sa google sources ay ang sumusunod:

18 x 31 x 6.8 mm atsaka 20 x 31 x 6.8 mm....

yung 20 x 31 x 7 mm meron sa mga auto supply...yung 18 x 31 x 6.8 mm e wala ako mahanap...mukhang nasa kit iyon.

lumalakas na kasi tagas nung harap ng injection pump as evidenced nung mga diesel leaks sa likod at harap ng timing gear case cover.

TY

20 X 31 X 7 or 20 X 31 X 6.8 are both OK.

Our 2-in-1 invention consist of an electromagmetic component and a electrostatic component.

Napansin ko, if after some time, I open the air induction hose, I notice so many dust clinging to the needle sharp transducers. Its difficult to brush this dust because they are negatively ionized. Baka pwedeng lagyan ng maraming metal mesh para gawing air intake cleaning system, don't you think? Thanks for this thread.

Since original car manufacturers don't produce a similar product for their cars such as yours, I don't see a need for it. A good intake air filter should be sufficient. It will also be easier to clean and/or replace.

Meron bang 100% effctive air filter? Bakit pagbukas ko ng mga engine na nakabitan namin ng device/s. kapal na dust. kapit na kapit dahil neg ionized. "Air cleaner na, fuel saver at engine enhancer pa!" hehehe thanks sa thread mo.
