Laging sinasabi na "hard and expensive" to maintain a diesel engine, bakit po?

[enrico]

matanong ko lang sana bakit "easy maintenance" ang gas? or conversely, why is it so hard (expensive?) to maintain a diesel engine?

is it still hard and expensive to maintain the new generation of diesel engines or only applies to the old ones?

lagi ko kasi naririnig na magastos/mahirap ang mag maintain ng diesel.

sana matulongan nyo ako!

salamat!

[impulzz]

not really, maintenance is just the same actually, compare this sa gas engine tune up you change the oil and filter, sparkplugs, fuel filter, clean or replace air filter kung luma oto mo add the contact point, condenser.

sa diesel tune up is change oil and filter and fuel filter & clean or replace air filter too.
so basically halos parehas lang di ba. sparkplugs lang ang iba.

[av8or5]

aside from the post above.. mahal din kasi sa diesel engines usually need more oil than regular gas engine and may at times have two filters instead of one.

one of those is when it comes to calibration and overhauling charges
by machine shops.

baka mas nagiging magastos ang diesel kasi mas madalas mag pa tune up ang diesel engine compare sa gas fed engine

yun TD42 ng Patrol, since I got it last 2003, once lang ako nag pa adjust ng valves, once lang nag palinis ng injectors. yearly palit ng fuel filter (2), every 5,000 km oil change 2-filter*300 ea. and 10 liters of oil, every 3-6 mos palit air cleaner.

[Djerms]

Gastos ko for a regular oil change is around 2,000 a month for everything. Kung may pera naman at nataon sa major checkup (I do it every 20k), mga 7-8k ang gastos. Hehe.

This is for a Dmax AT.

have had my starex since dec 2002, got it second hand.. but had only 17,000 on the odometer..... up to this very day. i havnt touchd the engine,, except replacing the water pump and timing belts... and engine oil change of course...i dnt even hav a regular sked for oil change... and it still runs perfect...

hope it's not OT: sir, tuwing kelan ba dapat palinis ng injectors? my ride's a 95 safari. thanks

[SIZE=3]I'm an owner of an Isuzu elf 4be1 light truck..in my experience with diesel engines its more cost effective in maintaining one. as long as you regularly check for wears on your fan belt, loose bolts in you engine bay and engine support, wears on the wires of your alternator, your atf level, steering performance, battery water level(which is commonly neglected in diesel engines) including its clamps, check of oil level(which i do every day),regular change of engine oil and its oil filters(every 4T kms or roughly 2mos of daily use),water level in your radiator and its reservoir,cracks in your radiator hoses and a clean air filter..then your ride will give you a smooth start every morning you crank your engine..as long as you all of those mentioned above wala kang aalalahanin..ive been using mine for the past 6 yrs na and every visit to the emission test center less than 1% pa din ang grade nung makina ng truck...much to the delight of the emission personnels..ang pinaka major na naging problema ko is palit lang ng clutch disc..hehe..as with your injection pump being cleaned..hindi basta basta ginagalaw ito..unahin mong ayusin/palitan air filter mo baka marumi na at clogged o kaya yung hose na humahawak sa housing ng air filter(baka luma na at malambot kaya napitpit at walang mahigop na hangin) kaya mausok na sya..thats from my experience...my 2 sentimos[/SIZE]

[mangkaryas]

pahabol pa..aside from sir oteps response(which I 100% agree) kung mausok na diesel engine mo..wag yung injection pump ang sisihin agad ito muna unahin nyo:
1) check kung marumi air filter at yung hose na humahawak sa air filter housing(baka luma na at malambot na ito, kaya nag co collapse yung hose nyo hence humhina hatak ng makina at mausok..(basic)
2) ipalinis nyo lang muna yung burn/heat plugs nyo (conterpart ng spark plugs sa gas fed engine)..in time nagkakaroon din ito ng mga waste/deposits at corrosions.(mekaniko kailangan nyo dito)
3) ipa check nyo engine compression..minsan di nyo namamalayan na overheat na pala kayo kaso takbo pa rin at ang tinatamaan dito ay yung cyclinder head. maswerte na kayo kung repaste lang ng cylinder head ang ipapagawa kaysa sa replacement ng buo at siguradong butas ang bulsa nyo dito (ito naman ay kung paulit ulit kayong na o overheat)
4) kung sadyang mausaok na nga..ipa check nyo na sa calibration center at baka pinasukan ng tubig yung fuel tank nyo o kaya ay may halong tubig yung diesel na pinakarga nyo at corroded na yung mga needles sa loob ng injection pump..minsan kasi yung akala mong murang diesel e may halo palang tubig kaya mapapamura ka sa gagawin nito sa sasakayan mo :p
...at kung pagpipilian nyo ako kung alin sa diesel o gas na makina, sa diesel na ako..hehe..di ka basta ititirik nito sa baha(wag lang pasukin ng tubig yung air filter mo..at pag nangyari ito..paktay..katok ang makina mo 100%) o sa akyatan kahit na ba kargado ka..pagtyagaan mo nga lang ng konti yung noise level at sadyang mas maingay ang diesel

kapag po ang usok ay maitim na at makapal na po ang pagkaitim sir...dapt na po palitan ng injectors...kapag ang injectors mo ay ayos pa naman ang buga pero sunog na un po ang tinatawag na pwede pang irecon.....

[snowbound]

mas madali i maintain ang diesel. walang sparkplug, distributor, condenser, etc. madali paandarin. L300 gamit ko dati, tipid sa krudo. ang adventure, pareho lang ng makina, mura ang change oil, P180 oil filter, P150 air cleaner. less than 1t/change oil/3 months. kung pa balance ng injectors, P75/injector lang d2 sa amin. kung engine wash, spray mo lang ng gaas then water hose sa buong makina, solved na. kung parts naman, always available and affordable. kung gusto mo pang magtipid, daming surplus ngayon.

[afrasay]

if i remember it right sabi sa denso eh 20,000 km or eto ba yun replace na...hehe. depende din ata sa gamit. nun pina check ko sa denso the last time may 10,000 km to go pa ako and they just clean it and adjust the opening pressure.

i have had 4 diesels and 2 petrols.

Mas maselan ang diesel sa oil, fuel and water.

oil - you have to change oil and filters every 3K-5K to make sure bearings are well lubricated to handle the compression and engine stress from high torque - compression driven ang diesel hindi spark driven. Otherwise, pag nagasgas ung laman ng makina overhaul ka or kung di grabe damage, puro usok at wala hatak.

Fuel - there is no automobile grade diesel in the Phil. Industrial grade lang kaya mejo madumi ang diesel dito at very low cetane ratings. Ang diesel abroad kulay tubig at pag sinunog mo walang usok. Dapat pag 1/4 - 1/2 na ang fuel tank mo, pa karga ka na para hindi pasukin ng tubig at latak ung injection pump. Otherwise calibrate ka pag nasira injection pump. Some benz owners add kerosene to the diesel to clean the lines. Wag ka rin magpapakarga ng diesel sa mga station na binabaha - may tubig na tanke nun o dun sa mga luma station na kalawang na ung mga tanke - sayang injection pump mo.

water - like any car, but more so for diesels, dapat never ka mag overheat. Make sure you always have water in the radiator or put an aux fan kahit kaya pa. Maselan ang diesel sa tubig. Umiinit yan sa akyatan or hatakan. Mas maganda performance ng malamig na diesel. King di ka maingat baka di mo mapansin na nagooverheat ka na - laban kasi parati diesel kahit mainit na mainit na di kaya ng gas na namamatayan.

Calibration - contrary to popular belief na dapat mag calibrate lang ng diesel pag nasira ung injection pump, dapat actually magpa calibrate every 3 - 5 years depende sa galing ng nagcalibrate. Un na ung tune-up ng diesel para humataw, humatak at di umusok.

Nozzle tips - have to be cleaned at least twice a year sa calibrator for good engine performance. Mga P300 or so lang naman un

Marami diesel owners na di marunong mag maintain ng diesel kaya sumasakit ulo nila at nabubutas bulsa nila. Dont expect your wife to take care of a diesel if she is not into cars - masisira lang un - best pa rin gas for the chics. Ang gas engines kahit 1 year ka di magpalit ng oil and filters mejo ok pa rin.

Despite all of that, diesel pa rin ako. Mas gusto ko ung performance at tunog pag lumalaban sa bundok. Mabilis din naman sa highway pag rekta. Super tipid pa. Madali lang naman alagaan kung alam mo ung dapat gawin.

Good luck sa choice mo bro.
