Top Overhaul...

[sirkosero]

baka naman valve cover gasket lang? pag cylinder head dapat bluish ang usok ng tambucho

Hello po I'm newbie when it comes to cars just had my 1st car a month ago Mitsubishi Lancer 1997 1.3 engine carburetor anu pu ba signs if kelangan ko na tune up or over haul ung engine?

Hello po mga sir, Una po sorry for necro'ing a post but I'm new in the forum and I still need 5 thread reply to create my own thread. I posted here since eto po yung topic na most relevant sa problem na na-eencounter ko ngayon.

About the car, It's Nissan Sentra LEC 1992, carburetor, manual trans and my area is San Pablo City, Laguna. Last July 21, 2015, pumalya yung 2 sa spark plugs nya so I made a replacement with new sets of spark plugs and nag-okay na sya. Pero 12 days later (2-days ago) ay ganon nanaman sya so dinala ko sya sa mechanic and I found out na may oil leak sa isang spark plug plus naging mausok sya, white yung usok nya.

I was thinking na pa-top overhaul ko na sya, change cylinder head gasket and piston rings. And my questions mga sir; Do I or not really need to top-overhaul my car's engine? If ma-top overhaul sya, will it solve the oil leak problem sa spark plug? Mawawala na kaya yung usok nya?

Thanks po mga sir! have a good day!


EDIT: and nag-jejerk din yung car since.

Have your vehicle compression tested first so you can determine what exactly may be wrong; a wet and dry compression test will say if its your piston rings or gaskets that are busted.

Thank you sir Vin, I'll take your advice. I will post update here as soon as I get the result of the test.

Dugtungan ko na lang thread na ito....

Need your help guys, sabi ng mekaniko my 98 Corolla Lovelife GLI AT needs top overhaul. When I read this thread last night I asked if he conducted a compression check. Hindi daw. Pero may singaw daw syan nararamdaman.

Was wondering if anyone can recommend a shop that can do a compression check, preferably sana in QC area. Pero if outside of QC ok lang I trust your suggestions.

Symptoms:
1. Loss of power
2. Parang hihinto at low speed
3. Idling does not sound right.

a decent talyer and a good mekaniko should have a compression test.

kung wala, hula-hula lang yan.

try mo servitek. usually complete sila gamit.

you can also try speedyfix in san juan.

personally, i just bought myself a compression tester for 1.5k

Sorry for late response on this question. But as they say, better late than never.

Anyway, pwede mo rin muna palitan yun oil seal nun sa port ng spark plug na apektado. Easily accessible at surely na mura lang at hinde ka na gagastos ng pang top overhaul.

Hi, this is also my first time here, good thing may ganitong forum, sobrang dami ko natututunan...4mos na kami ng mitsubishi lancer 97 ko and may mga sakit ng ulo nadin bnibigay saken but I think normal yun dahil 2nd hand ko na sya nabili.

So far, maganda performance nya, kakapalit ko lang ng fuel pump kasi nasira last week. Aircon compressor nalang problema ko and top overhaul (daw).

Please advice me guys re top overhaul, kasi everyday naglalagay ako ng tubig sa radiator ko para di mag over heat, advice saken ng ilang shop na napuntahan ko is top overhaul nga daw. Tama po ba yun?

Tsek mo oil cap mo kung may halong white color ang langis, kung meron dapat na nga top overhaul yan kasi naghahalo na langis at tubig dahil may tama na ang water jacket. Base sa experience ko lng.

Check mo muna bakit nag uubos ang tubig o coolant. Pwedeng leak sa radiator, radiator hose, water pump, at radiator cap. Minsan kasi yan radiator cap sira na yun pinaka seal nya o minsan naman sobrang baba yun pressure na hinohold nya kaya labas ng labas ang tubig pag naandar. Check mo rin radiator fans baka hinde naman nagana ng maayos kaya nag o overheat kaya nagbabawas yun tubig.

As suggested i-check mo filler cap for signs ng moisture. Check mo rin engine oil dipstick, baka kulay 3 in 1 na yan, meaning nako contaminate ng tubig ang engine oil, so possible na singaw ang cylinder head o bumigay na yun gasket.
Pwede mo rin tanggalin yun radiator cap habang malamig then start the engine tapos observe mo if kaagad bubulwak yun tubig mula sa radiator. If ganun meaning may singaw nga cylinder head.

Check mo muna yan mga items na yan before ka pa top overhaul sayang gastos.

Had the driver bring it to Mega motion in banawe.

Was able to have the compression check done. Surprisingly ok pa naman daw. 100 ; 90 ; 90 ; 90. Tama ba na 75 daw minimum while 150 daw yun best results? Noob sa mga ganito pasyensya na bec this info was just relayed to me by our driver who brought it sa shop.

Also the culprit according to the mechanic was the wet sparkplugs from the engine wash. It was replaced. Bumalik na rin power nya.

However sabi sa akin top overhaul parin daw should be done soon, so as to avoid bigger problems in the future.

Based on the compression results can I still defer the top overhaul?

Salamat

[sirkosero]

mababa ang reading. pantay pantay naman but still some work needs to be done.

sana nasubukan mo mag wet compression test din. its done by putting a few drops of oil sa spark plug hole then cranking the engine for the compression test.

kung gumanda results, be prepared for an overhaul since piston rings are worn out.

kung no change sa reading, you would have to do top overhaul only.

Thanks bro. Will bring it back for wet compression check. But just assuming i would need top overhaul only. Based on the "dry"compression results i got, how soon should I have the top overhaul done?

[funkeemunkee]

ASAP. Habang pinapatagal baka mas lalo lumala.

If the test was done right, these are low readings.

The throttle must be propped full open

Dry
First puff Four puffs


Wet

First puff Four puffs

All tests done with a fully charged battery and preferably connected to a charger. The average for first puff is 50 psig and at four puffs at 120 psig

even with a correct compression test, the most reliable test for combustion chambers integrity is the cylinder leakage test. this is done with the cylinder at top dead center compression stroke and compressed air is pushed into the spark plug hole through a cylinder leakage tester

http://www.southbayriders.com/forums...hments/313840/ with each cylinder tested. while in the process, should there be loss of reference pressure, listen for noise of air escaping at the tail pipe, oil dipstick tube, oil filler cap, intake/throttle body and observe if the radiator coolant is bubbling. this will point as to whether there is compression loss and where or what was causing it

Ang problem mo ay madali maubos ang tubig sa radiaror mo.... So . check muna kung may leak sa cooling sytem ng engine. Gaya hose, drain plug ng radiator, water pump. Much better na mainit makina at umaandar pa... Mas madali makitya yun leak kung may water pressure.... Yun konting moist ay malakas din makaubos ng tubig ng radiator..

To confirm naman kung dapat ka pa TOH ay tangalin mo muna 4 spark plug at silipin gap or insulator.... Dapat walang sunog na oil or basang oil sa gap at thread ng spark plug...

Dapat light brown or greyish white ang normal kulay nmg gap ng spark plug...
