Sir, i have a musso w/ a 5cyl diesel engine, I was told that I need to replace the o-rings on the it inline injection pump. Do you have any idea where I can source the parts? I think the injection pump is a bosch. Thanks

The o-rings are included in the pump overhaul Kit, which we have. The o-rings are not available separately.

Check / replace fuel filter. Baka barado na ito, o baka pinapasok ng hangin ang fuel system. Kelan yung huling fuel filter replacement?

engine is 4d56 NA in a mitsu L3FB ... problem is ... upon running for a few meters and slowed down or stop, engine shakes heavily that I need to rev the engine higher to keep the engine running ... failing to step on the accelerator pedal would cause the engine to die ... I used to experience this engine behavior when I'm low on diesel but now I am experiencing it even on half or full tank of diesel ... performed the following already: fuel filter check (it's clean/unclogged upon disassembly), fuel lines check (no fuel leak or air getting into fuel lines) ... currently, the engine emits a moderate amount of black smoke when revved. Do you think that the "engine shaking" might have something to do with the injection pump's or injectors' condition?

Let me know your thoughts sir. I would really appreciate them.

Thank you.

What's your engine mileage?

It could be a fuel filter or an injection pump problem.

it's rather an old engine and was rebuilt twice already ... the last one being in December of 2009 ... according to the former owner, the last time the injection pump was checked was more than five years ago ...

sir dieseldude,
puede ko ba mapa diagnose my kia carnival a/t 2001 model 2.9 tdic
the problem was mausok and mahina ang humatak,nagbabawas ng oil

we did engine overhaul 4 months ago and took good break-in.
during that ok naman humatak and hindi mausok
then we changed oil recently then problem comes mausok na sya and medyo humina ang hatak
my trusted mechanic told me that turbo is the culprit.

thanks

sir dieseldude,
fyi.we decided to brought down the turbo assembly. we found out that the spacer inside the turbo(washer) had sign of wear.
loose spacer enabled the oil passed thru the turbo system.
what we did was we fabricated spacer(machine shop) slightly bigger than the
old(micro mm difference).
right now my carnival runs well.

Sir dieseldude
we've noticed na umingay tunog nang makina(alterra 2005 37k ODO) after i switched to 5w-40 fully synthetic castrol edge plus from using 15w-40 mineral oil.So far maganda naman sir performance sa highway kaya lang umingay pag rev ko pag city driving.is there something i should worry about 5w-40 synthetic in our tropical climate? masyado pu bang malabnaw ito when advised sa manual ay 15W-40.Need help na pa praning lang sa tunog ng makina maingay pu kc.Wala kc fully synthetic 15w-40 except royal purple.Do you advise me to try royal purple or shift to 15w-40 synthetic blend like caltex delo sports?Thanks in advance.

I don't think 5w-40 oil will cause noisy acceleration. I hope you can validate this and post your findings.

I always stick to the manual's recommended lube.

Hi Sir Dieseldude. Itanong ko lang yhe easiest way to tell if the turbo of a 4d56 engine is functioning. kasi parang hindi hindi sya gumagana especially kapg na hit nya 2000 rpm. I have a montero kasi. when i accelerate and the rpm touches the 2000 mark, madidinig mo and feel the response of the engine.

Hope you can help. Thanks in advance.

PS.

May alam po ba kayo tungkol sa rotrex supercharger?
