AFAIK, puwede lagyan yung old school diesel ng 2T sa fuel tank para makatulong sa decarbonizing. 128:1 ang ratio para safe. Done it already. No problems so far. Still checking the FC if it will improve but i doubt it. Decarbonize lang talaga.

Sir, black smoke po yung unang lumabas, then followed na ng white smoke... Ok lang po ba yun? TIA

pag black smoke,it means,kelangan i decarbonized or i flushed mo ng tubig yung tambutso mo bro...ganyan kadalasan ko ginagawa...pag white smoke naman,kahit mainit na makina mo or malayo na tinakbo mo,pero visible talaga yung white smoke,then sa nozzle na yan,mauling na yung nozzle mo kya hindi na "mist" yung buga ng diesel sa combustion chamber...

pero according to your post,mukhang pareho mong kelangan gawin yan...parang medyo kulang ka sa maintenance,hehe...saka yung white smoke,di lang mabaho,masakit pa sa mata...mura lang naman palinis ng nozzle...yung paglinis ng tambutso,pwede na sa carwash yun or kung may hi pressure ka,I DIY mo nalang...

hi there sir! Im also a 4ja1 engine owner. recently i just bought a hilander mdl 97 from a good friend of mine, at first everything else in my car seems to be in perfect condition not to mention the engine. but lately ive noticed that everytime i drove the car in long trips especially during hot and humid day and try to check my engine oil dipstick lever i notice a white smoke coming out from it with a little bit air pressure and there are times that the oil dipstick lever puffed up which i believe due to the air pressure inside the engine. is my engine are in need for total overhaul already??? hope u could help me and give me some advise! thank you and godbless!

wala naman problema 4ja1 engine.. un nga lang medyo mabagal pero kaya sumabay sa akyatan.. hamunin mo ang advie at innova vs crosswind kahit may 2rbo pa ang innova sasabay parin sa akyatan yan or mang iiwan..

Sign of blow-by yan. Better have a compression test. Search mo lang dito mga threads regarding where to go for compression tests.

Or better yet, go to a tructed mechanic.

Agree talaga aku sa inyo mga fellow tsikotters masyado talaga mausok at saka tapang ng amoy. Everytime nga pag pinapainit ku ang engine uma.alma yung mother ku kasi umaabot sa aming bahay ang usok. Hehe!

Malakas tlaga mg vibrate ang xwind tapos mabagal din ang takbo.
Pero as of now wala pa naman akung na encounter na major probz sa xwind. maintenance lang....

Thanks.

Sure, the vehicle would still run but performance would be compromised (as signs begin to show). As I was told, lahat naman ng diesel engines are "Blow by".... I guess what matters is to what extent is it blow by. Kaya as Ry suggested, best to confirm what steps are required to remedy this..... likely an overhaul.

Thanks sir Benz, naitanong ko rin lang kasi meron din akong na-observed na minimal amount of smoke coming out from the dipstick hole, so far wala pa naman akong nararamdamang pagbabago sa performance ng unit ko as to power, fuel consumption, decline in oil level however, this is one of the signs that my engine is already aging and should not be taken for granted.

Thanks.
