4DR5 Engine Wear and Tear

[Dudee]

Hi, for all mechanic and experts..

For 4DR5 engines, assuming with consistent oil change and tune-up. The unit/vehicle has runned 200+K mileage in 6 years.. company service kasi. What problems do we expect? Should we expect Piston replacement or overhaul?

Timing belt and other belts have been change. Evaporator have been changed na rin.

200K+ mileage is way too high, di ba?

Any inputs...??

sa diesel engines not really kung properly maintained sya. On the other hand 200K km in 6 years? mukhang bugbog. That's 30K km/year! Palagay ko ready ka for at leasta top overhaul.

[g-shock]

hi dude,assuming 230 km a day ang tinatakbo ng oto mo,for 6 yrs ,sa tinign ko kailangan mo na nga ng full engine overhall, d lang top over para isang gawaan lang ,papalitan mo nang dapat na palitan .pamasada ba yang oto mo ?

L300 FB ang unit binebenta sa akin, kailangan daw ng pera kaya pinapa rush sale at 180K, 2000 model. Owner is PRYCE GAS Company. Malinis ang papeles, they got it brand new.

If the engine is maintained properly change oil every 5k km or 3months and there are no signs of oil consumption, hard starting or even smoke belching then you dont need to have it overhauled. But to make sure go have a compression test on the engine then you can decide if the engine needs to be overhauled.

i thought L300 have a 4D56 and not a 4DR5?

Tama pala noh... it's 4D56. My mistake.

[mikbik]

sir, kung sa basic inspection nyo eh ok naman so need for overhaul agad.

use a good engine flush and a good oil ok pa yan.

[wildthing]

mausok ang napabayaan na 4d56 engine...

Palitan mo nalang agad ng timing belt para sigurado, baka kasi medyo matagal na din napalitan yung belt at nalaspag na ng gamit. Bago ka mag test kung mausok yung engine, check mo muna kung malinis yung air cleaner. Pag madumi yun, for sure pag nag rev ka e mag uusok yun. Kadalasan kasi yung lang ang cause ng smoke bleching at dirty fuel filter. 3 years din ako nakagamit ng second hand L3 van with 4D56 engine, wala naman ako naging problema. Just followed the maintenance regularly.

Just sharing my experience.

Ang alam ko pag L3 FB palaging mausok. hehehe

Mausok siya when I gave a rev sa pedal. So far, tahimik ang engine pag nasa idle (but di yata ito magamit as basis, di ba?) .... Power steering still works... Sigurado timing belt at all the belts kailangan ng palitan...

How do you test for loose compression? Di ba overhaul na kailangan pag loose compression?

My base Q would be, in any 6 year old vehicle/unit, assuming di naman PALAGI mabigat ang karga, 200K mileage ang takbo, parang kasi ginawang Taxi/pampasada... Wouldn't the engine SUFFER a lot din?

200K divided by 6 years == 30K mileage in a YEAR.. Parang nakakatakot, di ba?
