thanks po

HIndi ko alam. Depende yan sa ang problema ng EFI system.

Meroon failures na progressive, ibig sabihin nito.... palala nang palala.
Maron naman failures na hindi progressive, or hindi dumadamay ng ibang parts.

hi sir dieseldude...

tanong ko lang sana kung paano magdrain ng water sa fuel filter...my van has a 1KZ-TE engine, super custom yung galing subic... Sa fuel filter mismo.

tsaka nakakasira ba ng ECU pag may welding job sa body? Normally hindi. Pero, mas safe kung i-disconnect ang batteriy. Impotant din ang attaching points ng welding ground and weld point.

TIA...

may tumutulo po sa fuel injection pag start po ng umaga pero pag mainit na po yong makina e nawawala po, ano po kaya problema nun?

Baka matitigas na ang mga gaskets and rubber seals dahil sa katagalan ng gamit.

Madalas ito mangyari sa old pumps.

Sirs, good day po,
i have problems with my nissan bd25 engine. when accelerating it emits white smoke after idling the engine for 5+ minutes.idling is also rough but when at 1000-3000rpm its smooth, at 3000+ rpm engine sometimes misfires and emits gray to black smoke.engine response is compromised.

i recently changed the oil, all filters oil,fuel,air but it did not change.it runs 10km/L city,12km+/L h.w.
there is little clear blow by gas at the oil filler but none at the dipstick tube but it consumes 1 liter of oil per 3000kms+.
what is the correct idle speed for my engine?
is the rate of oil consumption normal?
faulty engine?
faulty injection?
I hope you could help me out, thanks.

This could be an indication of low compression due to insufficient valve clearance. Compression improves as engine rpm increases.

i recently changed the oil, all filters oil,fuel,air but it did not change.it runs 10km/L city,12km+/L h.w. Good.
there is little clear blow by gas at the oil filler but none at the dipstick tube but it consumes 1 liter of oil per 3000kms+.
what is the correct idle speed for my engine? Approx. approx. 750 rpm
is the rate of oil consumption normal? Oil consumption is ok.
faulty engine? Maybe. Check valve clearance, then perform compression test.
faulty injection? Could also be. But first verify injection timing if correct.
I hope you could help me out, thanks.

Good morning Sir,
Saan po ang shop nyo? kasi yong pajero ko papagawa ko po sainyo...lately mausok sya ng puti at pag uphill yong automatic trans nya ay keep on changing gear at napansin ko rin ang top speed nya ay hanggang 110kph na lang dati napapaabot ko sya ng 140-160kph.

sir diesel dude,
i recently acquired 2nd hand toyota hilux 3L. my fuel consumption is bad, it's only 8 km/li combination of city and highway driving. i had talked to other hilux owner saying that their rig does 10-12 km/li.

i noticed na mausok ang car emitting black smoke everytime i press the accelerator suddenly from 1.5k rpm up to 3.5k rpm. i had new changed oil, oil filter, air filter, fuel filter but no help. could it be of my nozzle tip ro injector pump problem? please help.

also, lakas ng vibration at 1.5k rpm.. thanks..

Bawal ang mag post ng commercial details sa Tsikot forum.

PM na lang kita.

I would have recommended checking and/or replacing the air filter, but you've already done it. Is your air filter original? If not, the filter media could be undersized, therefore restricting air to your engine. Try removing the air filter element temporarily to see if smoke is less.

could it be of my nozzle tip or injector pump problem? please help. If your car still smokes a lot after the above suggestion is performed, it is possible that the injection pump is faulty.

also, lakas ng vibration at 1.5k rpm.. Faulty engine supports?

thanks. You're welcome.

Is engine power ok?
