Diesel Engines Maintenance Do's and Don'ts

**HITMAN*47** · October 29th, 2002 11:02 AM

Hi Diesel Experts people. I'm new here and I just want to learn more on how to maintain diesel engines making it it top shape condition always. Any Do's and Don'ts on preserving its engine. BTW, I'm planning to buy a second hand AUV this weekend. But to tell you frankly, I have no idea in diesel engines. Any tips on what should I look for before buying second hand AUV. Any info will be much appreciated.

Maraming Salamat po.....

A tip I learned from diesel guru Dieseler:
*It is better to buy the cheapest air filter (~Php150.00++ at Glenn10's shop) you can find and replace it during EVERY oil change than buy an expensive air filter which you replace only every other oil change. A clean air filter does wonders for emissions. Of course, kung reusable ang air filter mo, then you don't have to replace it.

Sir OTEP, Salamat po sa pag tugon sa aking katanungan..Tungkol po naman sa Engine compression, Paano malalaman kung okey pa ang compression ng isang diesel engine? Saan po ba pwedeng ipa check ang compression nito? Any shop ba, pwede? Anu-ano ang mga compression values na dapat makita? Pasensya na mukhang naparami ata ng tanong..Gusto ko kasing dalhin muna yung AUV sa mechaniko or pa test para sa compression.... SAlamat ulit...

Dinamay pa ako heheheheh... :wink:

Speaking of Glenn, what is his exact store adress pala?

Hi Hitman,
It would be good if you can bring along a mechanic so that he could check the engine of the 2nd hand ride.... para sigurado.

Also, try knocking around the AUV, to check if it has 'collision damage'. Yung use your knuckes and knock around the body.

Tapos look under the place where its parked, to check for leaks. Dapat walang puddles of oil, water and what-have-you.

Tapos TEST DRIVE ninyo... pag-ayaw nilang pa-test drive, then do your own driving, as in drive away as far as possible from them... hehehehe..

Talyer ni Glenn nasa kanto ng Kamias at Kalayaan. It's hard to miss kasi katabi siya ng Equitable Bank and halos kanto na sila (yung bank ang nasa kanto).

9218831 ang phone number nila.

**fierari** · October 29th, 2002 02:23 PM

always replace your fuel filter para yung dumi ndi na umabot sa injectors

**kimpOy** · October 29th, 2002 02:28 PM

kapag bagong start dont rev muna slowly but surely tamang tama umiinit ang makina,
dont use diesel additive IMHO

lapit lang pala shop nila Glenn samin... sa UP Vill lang ako...! mabisita nga minsan...

kapapapalit lang po nung nozzle tips ng delica namin (4D56 turbo), together with air and fuel filters

ok na takbo niya at wala nang usok :lol:

pero pag-biniglang tapak ng accel pedal, yung pagni-rev, ang itim ng usok...

yung pagpalit ng nozzle tips at filters na po ba ang 'calibration'? hindi po kasi ginalaw yung injection pump, ok pa raw

ano po kaya ang kulang? :cry:

pasensya na po at gas engine lang talaga ang alam ko 8)

salamat po at hintay ko ang replies ng mga diesel gurus

**HITMAN*47** · October 29th, 2002 03:18 PM

KimpOy, bakit mo nasabing masama ang gumamit ng diesel additives, any bad

experienced on this? How about yung paggamit ng oil flushing sa makina, ok ba 'to?

Sa mga nag- reply Salamat ulit....

**fierari** · October 29th, 2002 04:09 PM

hanggat maari iwasan mo yung flushing kasi pag drain mo ng oil na may kasamang flush naiiwan yung ibang flush sa loob. pag lagay mo ng fresh oil mahihirapan sya kumapit sa engine components dahil may flush pa. magagas gas internals mo.

sa pagkakaalam ko po.

**crawdaddy** · October 29th, 2002 04:23 PM

what's flushing? and ano ba ginagamit sa pag-flush (ano ang naiiwan sa loob)?

hehe sorry kung stupid question! :D

**kupaloids** · October 29th, 2002 04:48 PM

crawdaddy: Kaya po gumagamit ng oil flushing yung iba ay para palabnawin yung langis. Sa ganitong paraan mas mabilis madedrain yung langis (specially dun sa mga oil stations na quikie and pag change oil).
Me personally, di ako gumagamit ng flushing kasi may natitira sa loob pag drain ng lumang langis. Yung makina po kasi, may mga parte na malalim at pwedeng mag stay dun ang langis w/ flushing. Pag naglagay ka na ng bagong langis, hahalo ulit yun sa fresh oil mo tapos palalabnawin nya ulit yun thus shortening the life of your fresh oil.

Whith regards to additives, yung mekaniko ng L300 ko dati, may experience sila na may naglagay ng additive tapos naging parang GEL sa oil sump at bumara sa internals. Ang epekto... TAO PO!!! Kumatok ang makina! :lol:

Hitman: Just make sure na susundin mo yung PMS mo. My practice is every 5000 kms. Change oil, palit ng fuel filter at oil filter. Every other change oil po ako nagpapalit ng air filter kasi twice a week ako maglinis ng air filter, may air compressor kasi ako sa bahay.

BTW, DIY po ang ginagawa ko every change oil. Overnight ko ginagawa tapos ijajack ko yung L3 sa opposite side ng oil drain para siguradong lahat ng langis tutulo. Tune up nalang po ang pinagagawa ko sa mekaniko ko every change oil.

Pasensya na po sa mahabang post. :mrgreen:

arl0011,

Hindi pa calibration iyon. Sa calibration, nire-recalibrate ang injection pump para tama ang amount, timing, at pressure ng fuel na dinedeliver niya.

**arl0011** · October 29th, 2002 05:01 PM

so sir otep, kailangan din ire-calibrate yung pump together with the nozzle tip replacement para ok lahat?

e yun po kayong black smoke pagni-rev?

salamat po uli

**OTEP** · October 29th, 2002 05:08 PM

Ichecheck na po sa calibration shop kung may kailangan pang gawin sa nozzle tips.

Dalawa po ang master calibrators natin dito sa board. Si Doc Diesel at si Hanson. Kaso mukhang busy sila making money kaya hindi maka-log on. :mrgreen:

Dapat mawala ang karamihan ng black smoke after calibration.

**fierari** · October 29th, 2002 05:12 PM

ayot nasagot ni kupaloids :D

natawa ko dun sa kumakatok ah hehehhehehhe

**arl0011** · October 29th, 2002 05:19 PM

aaaaH...so hindi lang pala nozzle tip replace

so kulang yung ginawa sa Betan? :shock:

salamat po sir Otep, at ipadadala ko uli dun yung oto, para ma-calibrate

sayang naman kung bitin din ang pag-maintain

salamat po uli

**crawdaddy** · October 29th, 2002 05:27 PM

kupaloids-
thanks! ok lang mahaba ang post, very informative naman! Super NuB pa naman ako! :D

**kupaloids** · October 29th, 2002 05:33 PM

OTEP e-epal ako ulit ha... :lol:

arl0011: Yung sa tanong mo tungkol sa pag rev, baka naman binibigla ng tapak sa pedal pag rev. Dapat dahan-dahan lang. Mas mahirap kasi sunugin ang diesel kaya pag inapakan ng bigla, yung sobrang diesel e magiging black smoke. Di po katulad ng gasolina na halos instantaneous ang pag sunog.

Check mo din yung exhaust pipe, baka makapal na ng karbon yung loob. Yung iba naglalagay ng water inlet sa may ibaba ng exhaust manifold tapos dun nilalahgyan ng hose at tubig tsaka irerev. Di ko pa lang nasusubukan yun.

Kahit naman po sa tao pag binigla mo ng isang galon ng tubig ang inom, mabibilaukan at sisigok din yun :lol: j/k :mrgreen:

crawdaddy salamat din, at least you found my post informative. :D

fierari: Tama ba yun? TAO PO!!! o MAKINA PO!!! ? :lol:
