4D56 Valve Clearance Adjustment

**roydok** · July 28th, 2003 09:41 PM

What is the appropriate schedule for valve clearance adjustment for a 4D56?

**Ungas** · July 28th, 2003 10:21 PM

From my pov, all valve clearance for any given engine should be checked at every 30K kms. Some older engines have 14 gap clearance while other newer engines should have 16.

Madali naman po marinig if the tuppets needs adjustment, may maririnig kayong naglalagatikan sa loob ng valve cover.

HTH :D

Ako, when needed lang. :D Pag maingay na.

**Sheep** · July 28th, 2003 10:58 PM

oh lagitikan and maingay?
napansin ko na medyo umingay na ang sound ng engine ko d na kasing pino before
after long drives about 2-3 hrs after turning off the engine when i open the hood i hear ticking sounds d naman continous random sya (ito ba yung lagitikan na sounds) or is it just the metals expanding ang contracting due to heat?

23000+ lang ang takbo ng ride ko last adjustment was in its first 2000 check up
kelangan ko na ba ipaadjust?
wala naman ako napapansin na power loss ok parin hataw

Kahit na malaki ang clearance ng tuppets, di po mararamdaman ang power loss. Maingay lang ito, this tends carbon deposits to build up the gaps.

sir so i have to get it adjusted?

**Ungas** · July 28th, 2003 11:10 PM

Not necessarily, Kung ganun na ba kaingay ang tuppets mo, then you will need it adjusted. Teka anong sasakyan ba yan at 23K pa lang ang naitatakbo?

mitsu L200 po sir almost 3 years na sa akin ito bihira ko lang gamitin
sabay ko na lang sa next change oil ko
thanks

**Sheep** · July 28th, 2003 11:33 PM

d pa naman ganun kaingay pero nadidinig ko na parang iba na ang tunog compared before.

and pag kaka start ko pa lang di na pareho dati na pino kaagad may nararamdaman na akong nginig (parang sinisinok) after 2-5mins nawawala na what seems to be thr prob?

regular naman ang change oil ko every 5000 sabay palit ng oil filter i always use orig mitsu parts ang hindi ko pa lang napapalitan ay ang fuel filter na nabasa ko sa manual due 20,000 km ito kaya ang cause ng pag sinok? sorry sir medyo ot pero ask ko na rin

With regards to your first querry, iba na talaga ang tunog ng makina after running 5K from its brand new state. Fitted na lahat ng internal moving parts. Ika nga break-in period is over. :D

On your second state, pag bagong andar ang makina lalo na after having it rested for a couple of hours. Bumababa na lahat ng langis sa oil pan. It is natural for your engine to sound like there is metal to metal contact, infact that is what's happening inside. It takes about 10-20 seconds before the oil gets pumped internally, ofcourse it all depends on how big the engine and its oil pump is. Kaya masama yung pagkakaandar pa lang ng makina then sabay ng mataas na rpm agad, let it idle and oil circulate first before putting more strain on your engine.

Di ko sinusunod pag dating sa mga filters ang manuals. 20K kms. kung nasa ibang bansa ka at siguradong malinis ang fuel na papasok sa makina. I change my fuel filters every 10K kms. Minsan nagkakatubig sa loob kaya nahihirapan ang fuel system, or pwede rin naman itaktak kung tubig lang ang laman. Kung dirt and grime naman, mas makakabuti pang palitan na it will just choke your fuel system.

Nakikipost lang po.

So, 14 yung clearance gap para sa mga 96 model na 4d56?

Nope, it is on 16 clearance gap.

**marwen** · July 29th, 2003 12:34 PM

pardon me for my ignorance.. ano histura ng valve clearance..

he.heh.e..

**pajerokid** · July 29th, 2003 01:27 PM

Frank, Ungas :: Ano yung 16 na clearance na sinasabi nyo? YUng gap? Gap for 4d56 is straight 25 - warm. intake and exhaust.

But then again baka pang TDIC versions lang to. baka iba sa N/A

**roydok** · July 29th, 2003 02:07 PM

Thanks for all the replies.

**Sheep** · July 29th, 2003 10:32 PM

Sir Alfred,
Sa manual, 10 supposed to be ang gap ng 4d56. Anong advantage ng mas malaki ang gap?

Hmmm.... parang mahirap explain kung ano itsura nun ah... well it is simply the gap between valve and adjust screw or in some other engines valve rod and adjust screw.

Yung binabanggit ng clearance na 10, 12, 14, 16, 18... 25 eto yung feeler gauge measured in millimeters ie; 0.10mm, 0.12mm, 0.14mm so on and so forth.

A mechanic told me once that it is better to adjust it when the engine is cold. May metal expansion daw pag warm ang engine and adjusting it would get different results.
