can i know the estimated cost for complete top overhaul for wira..

thank u..

Around Rm400+.... I done mine but with the mechanic that i know personally...

Depending on what needs to be replace.

If top overhaul kit, the part price is RM90-100.
If valve need replacement, 1 nos RM15-20.
Usually engine oil & filter will be change together, add that as well.
Labour charge about RM280-300 (inclusive of valve grinding).

why ur car need top overhaul??... producing lotsa white smoke??...

Where you guys quote it RM 300-400? It's really cheap, cause my friend did top-overhaul on his Nissan, cost him RM 900 (workshop in Bdr Sunway)

I am just thinking of doing top overhaul for my Nissan Sunny too
No blue smoke, but valve tappet is making loud "tat tat tat" noises around 2000-2500RPM.Only can be heard outside.

Otherwise the car's engine still can do wonders in power.

Wira top overhual is around RM400-500

thanks for the review...

my car overheat..and got a bit of oil leaking..

mechanic suggest me to do top overhaul..

I did a full overhaul for my Sunny at RM1400.

Added on October 26, 2008, 9:01 pmdid u check whether the water level reduce drastically?
if yes, check radiator & hoses for leakage.
if no, radiator might need servicing + cleaning.
next check if the water's flowing (water pump).

if head gasket 'kong' d or somehow the water get into the combustion chamber, then only u do a top overhaul.

I did for my Wira was RM500

how's the cost for 4G93P?
My car already start consuming engine oil more ler...
And white smokes sometimes getting persistent.

@sleeplessmeyes, i did mine at kuching...

@usus, for white smoke, u just change the oil seal should do..... around Rm400 and less...

i tot was d valve seal bro? ?
ard rm350 only~

Overheat and straight away want to do top overhaul?
Hold on that decision for a second.
Seems like you are a headless-chicken, not knowing what to exactly do.

Have your mechanic checked whether your cooling system is not blocked,leaking until no water, faulty radiator fan or even faulty water thermostat?
It maybe dirty, clogged and needs "flushing". Either goto a Radiator specialist, or buy a Radiator flush chemical and DIY yourself at home.

Try that and see if your engine still overheats.

Oil Leak? Find a bottle of leak preventers, example: GOLD EAGLE NO LEAK ENGINE OIL TREATMENT.
Otherwise ask your mechanic where is it exactly leaking.

Few months ago I bought a bottle of HOLTS RADWeld to stop my radiator leak, poured almost 1/2 the bottle and it stopped leaking. Saved me RM 100 repairs.

Dont look down at "off-the-shelf" chemicals in ACE Hardware or JUSCO; reputable/well-known brands can help you first in saving RM 100 over bucks of repair by following the instructions on the bottle.

hmmm~
mayb his car overheated n cannot move edi then how? ?

If really la car overheated, engine stopped and someone tries to start again, then no need to think for top overhauls, cause the user already damaged the seized pistons.

My sis's ex-Kancil experienced full overheating once so badly,due to burst plastic T-pipe near the carb, the engine just stopped by itself at our porch gate. After cool down for 1 hr, start the engine again and it was running fine, except the valve sounded abit louder.

I too experienced engine overheating on my Nissan Sunny due to jammed water thermostat at "closed" position.When the engine overheats, engine feels much more laggy but still able to crawl safely to a nearby petrol station.But couldn't drive home safely.
After thermostat repaired, the water pump gave way
But my engine runs fine after that until today....

So at least I have experiences in overheating situation.

mine also~
i damage my piston n did d overhaoul for my satria~

Do keep a spare bottle of water in the car just in case also

Mine was when I was going to Jusco with my friend's car
He didn't even realised his water temp meter is at max and he still drives gila. Ended up overheated and stopped at the paring tol there when we were about to park. Ended up pushing the car, and fill up the radiator, total no water at all. In the end, can start, radiator memang leak adi and still don't wanna fix

u dont need to do top overhaul....

thanks for the advice, man.

valve seal if engine oil is leaking...
oil seal is if smoke ler?

the other way round...

valve seal if smoke
oil seal if leak

oh ok thanks... then maybe both kena change edi

u got both leaking n heavy smoke? ?

hahah... think I could find any trace of leaking (fuh!)
Sometimes my car got steady white smoke.
so consulted a friend who is also a mech in Putra Heights, he said might as well try change valve seal 1st, see if it solves the problemo...
I will pick up my car in 2 days time to see the results.

overheating, check the water pump got leak or not ... the last time i spent RM$700 for a mechanic to solve my overheating problem, he never check my water pump ... end up is the water pump leak and i have no water for cooling the engine

Go to a car wash centre, tell them to shoot water at the bottom until kilat bersih, no kilat nevermind, lulz!. Drive for 2 days, go to your mech shop, he will then know what is the actual problem. To see where the oil is leaking from. This is the first thing you must do.

hi, how do you know its valve tappet sound? My car seems gt the similar situation, when I am driving beyond 80kmh, the soft tak tak sound can be heard....

What's the car odometer reading when this happens ?

i noticed this issue for awhile already , didnt bother it . But , now the oil lost is getting serious . My odo is 230k now

i noticed this issue for awhile already , didnt bother it . But , now the oil lost is getting serious . My odo is 230k now

just wana say, the tappeting sound is not a good indication of ANYTHING other than the valve clearances lari (and frankly it can lari very easily without causing any issues...) if u really wana diagnose oil loss issues... take note of whats coming out of your pipe in different conditions (e.g. valve seals, spew smoke during heavy deceleration where theres a vacuum pulling the oil in through the seals, constant smoke, possiby more during higher rpm's - rings)

even better would be to do a comp test or maybe even check ur plugs (visual check tells you alooot)

No colored smoke noticed, no oil stains on plug.. What's the problem that cause oil loss?

At 230K odo with a bit of tik tak sound, as suggested by lsm , it's likely valve clearance lari .........
in particular when no valve adjustment was ever done on this engine, ever.
One doesn't have to remove cylinder head to adjust valve clearance by competent mechanics and it involves only replacing gasket for valve cover .......... and I don't call this as 'top overhaul' which equates to more $$$.

As for coloured smoke , it is quite difficult to 'see' with untrained eyes and it may be wise to refer to an honest mechanics. Btw, what's the oil brand/viscosity grade/API ACEA specs that this engine has been using before and during oil consumption occurs ?

how much are you loosing? only 2 other ways it can be lost (tho im quite sure its being burnt, maybe in quantities too small ot notice or only when ur moving at speed)
i)leaks, should be quite obvious
ii)ur screwed and its going into your coolant... you should find oil in ur coolant (honestly unlikely cause it should be everywhere at that point)

About 40% according to the observation on dipstick...

I am not sure as I am not the direct owner of this car... I only used Castrol 15w40, 20w50 and nasa 20w50.. With nasa, I can feel the car response is better... Not much different between Castrol 20w50 and 15w40

not sure what 40% means but sounds like alot.... should be blowing blue smoke.......

usually ppl measure in, Xml of engine oil that needs to be topped up after X km.

For a wira dipstick , that 40 % means 0.4 L.
But, over how many km ?

Mine consume around 250-300ml, top up once app. 4000+km then around 8000+km it will drop to the middle/slightly below mark on the dip stick and its time to change to new oil. Any concern that i should note or rectify. Tq

Any blue smoke on cold morning start ? and during acceleration/decelaration ?

Mostly white smoke on cold morning, didn't notice any smoke on acceleration might be too little to notice and no stain on plugs

This white smoke of yours on cold morning start, is equivalent to 'blue' smoke I enquire about.
As stated above and I quote:

This white smoke indicates your car engine valve seals are hardened , and leaking oil from cylinder head into combustion chamber.
IF there is coloured smoke during acceleration/deceleration, it indicates piston rings are leaking engine oil from combustion chamber to engine crankcase.

not claiming ur wrong or anything, but leaky valve seals should burn blue(ish) smoke regardless HOWEVER possibly ts cannot tell it apart cause theres too much condensation to go with....

anyway given the severity of the issue, if it was a valve seal leak, it would show itself VERY obviously when decelerating (rev up, then release throttle, while the rpm's drop, you will see a cloud)

or you know... option B is easy.... 15 min job, check your plugs... leakky valve seals would completely foul up your plugs

You may have a point in water condensation playing a part with white smoke on morning start , though not expressly saying so.For all we know, there may actually be some condensation.
On top of that Senscents seems happy with spark plug conditions.

However as his engine is consuming like 0.7-0.8L engine oil in about 8000 km, plus the fact that 'bluish' colour smoke is very difficult to 'see' by untrained eyes , hence my position above on valve seal leaks.

Coloured smoke during quick acceleration or quick deceleration , in my humble opinion, would indicate engine oil leaking through stuck piston rings . I wish he can get someone to test this possibility for him.

ohh didnt realize he checked his plugs..... cant really think of any way to check rings other than a compression test.

assuming its really not mixing with the coolant and not literally leaking out.... cant think of any other way its getting out.

check at the exhaust whether there are this black smoke stuck there.

no need to start the engine.

Yeah the spark plug still holding up after a year or more cant really recall when was the last replacement, as i just service the car 3days ago. Ask the old mechanic, i think he's about 65 years old on the codition of the plugs. He says that it's still good to go, need not change since the engine are running smoothly.

As the oil consumtion still manageable, maybe can save on the repair works. Guys.. How much oil consume to warrant it as excessive & need to repair.
Maybe i'm using the 5-30 oil. too thin viscosity ?

ols stick to your factory recommendations, thx.

thinner oil does not mean better, too thin and very bad shit like your cams get eaten.....

What's the car model and odometer reading ?

Tq. I thought + - 10 viscosity should be alright. Being using 30 grade for the last 2 years.

Wira 1.5 auto. Odo 300k+. Still holding up.

My wira 1.5 had been on 15W40 since a top overhaul in 2003 or so, no noticeable oil leaks at 7000-9500 km oil change.
Last May switch to Total Energy 10W40 at good bargain .
Why not consider Petronas 3000/Supremo 15W40, as it may help with your oil consumption problem.
I wouldn't touch a xW30 in a 300k wira.
