Black Sludge and Toyota/Lexus

[ghosthunter]

the first owner used full synthetic after the 10,000km pms. and from the record, nasusundan naman ang every 10K pms. got the ZZ Dec 2007. using RP during oil changes every 10,000Km

Hmmm... I heard that the recommended interval was 5,000km between oil changes for the ZZ equipped Corolla because of the sludging issue.

I've seen the same thing on a Corolla in SpeedLab and it had around half the mileage on the odometer you have on your car.

is it better for me to just use mineral oils and oil change every 5,000 km?

typical na byahe per week ay 4x sta rosa laguna - alabang, 1x sta rosa - pasig.

bihira lang na ma stuck in heavy traffic.

[niky]

Even so... this being a tropical country, the heat is a big factor. 5k is best.

120,000 kilometers ain't too bad (though having a religiously maintained engine suddenly go still sucks)... but it might have lasted longer if the previous owners had followed the 5k instead...

I would suggest every 5,000km as a precaution on your specific model of car.

Or sell it off and get another car with less issues.

The original plan was to sell the Altis before the ned of the year and buy a new vehicle.

Anyway with the overhaul. I think the altis will run much better thatn when we got it.

[paulgozon]

I have seen one altis with a 28500 mileage on it, the oil gelled, so they replace the oil, drive it for around 200km and notice blue smoke, check the oil again, it has lost 2 liters, they added again 2 liters, but the smoke is still there, they called me to check it out. My first question when was the last time they had an oil change prior to the last time they did it, luckily the owner is very truthful to himself and said that, "that was very long time ago and he remembered that i was probably 5K and they put a long drain oil. Had to open replace the piston ring, for the rings are already stuck in their grooves, all over the engine from the topmost cooler part which is the valve cover to the lowest oil pan, all the oil passage, you can see this gelled oil. Clean every part of it. And recommended using mineral oil instead of synthetic oil and follow the 5km oil change interval. Up to now the engine still runs, with almost 100t km on it. IMO, this black sludge or gelled oil, is caused by not changing the oil, oil has its lifespan. using it beyond its time will cause to gel. I have also seen it in every kind of engine that has been neglected in its oil change. But other owners of car would not admit it, some would.

is there really a better way to avoid engine sludge or black death?

correct me on this one, please; coz after reading this, I think this is what am gonna be doing:
- change oil every 5k kms.
- change oil filter (original Toyota Oil filter)
- flush engine and let it run for 5-10 mins

what is your idea about some mechanics, blowing some air using a compressor on the engine before they put the new oil, para daw matangal ang dumi at mga naiwan na residue? how reliable is this one....

:car:

Heavy oil particulate will be the last one to drop, the heaviest will be the slowest and most likely will not drop, this will require a little push from a short burst of dry air from a compressor, just a burst or two. Some will agree, others may not, because air contain moisture. But for me, I do it, because i have a good air/water separator with my air compressor and also, just a burst or two. Some oil pans are have been deformed by stones or whatever, whereby some portion of it is actually lower than the drain plug. But to be sure, i just ask my customer whether, to use compressed air or not.

Tumirik kahapon si Mrs sa SLEX, dala nya ang ZZ. napatow nya papunta sa mechaniko namin. Ng buksan ang makina. SLUDGE!

Sorry camera from a phone ang gamit.







DOHC ang makina. iyong exhaust cam hindi umiikot pag inis-start ang makina.

for complete engine overhaul. then sa weekend, ipapa machine shop ang makina

any update sir mel?

[meledson]

have to buy a new cylinder head.

natapos na sa machine shop, konting linos pa by the mekaniko, then i-aasemble na ang makina tomorrow. Mybe by sunday, puwede ng isalpak ang makina sa engine bay.

yan ang problema sa gumagamit ng synthetic oil.. kasi they tend to extend the change oil interval from 5k to 10k kasi nga naka synthetic..

others would say mas tipid kahit mas mahal ang synthetic oil due to "longer change oil interval"

try using semi synthetic or regular oil and change every 5k mas ok yun.. you used synthetic oil siguro kasi alam mo na "sensitive" daw yung engine ZZ sa sludging but still nag ka sludge pa din

nakakita na ako ng case before ng sludging sa mazda 323 engine.. well maintained yun using synthetic oil ayun nag sludge at inoverhaul din.. bumabara yan sa oil galleries kaya titirik yung engine hirap na kasi.. pero yung mazda ko dati regular oil lang

been using semi synthetic and regular oil sa past cars namin and hindi pa nangyari yan sludging..

Im not sure if this is related, was searching for some leads with my problem.

1. I own 2010 Camry G... casa maintained every 5K... with 12K on the odometer.
2. I had a warning light (actually spelled out in the info display): Low Oil Pressure
3. Check oil and it was in the right level... and NO overheat
4. Brought to casa thinking its just a reset in the computer
5. After 2 days trying to isolate the problem... Service adviser tells me that engine has to be opened through the Valve cover (which lead me to this thread)
6. Casa is efficient in servicing my car and have repeatedly informed that I have nothing to pay, though I know they are just trying to manage me instead of me complaining (though will take 1-2 weeks)

With what I read, and what they are doing, it seems its like oil sludge, pero para naman sobrang aga :-(
Will my car be reliable enough after this?... back of my head feeling the engine was already opened... family car ko pa naman for out of town trips.

If there is any consolation, I have nothing to pay... and they say they will fix it properly.... I did ask for documentation, the least thing they can do.

Make sure you now what really happened so that you can ask their specific advice on how to prevent it from happening again. So that when it does, it should be repaired free of charge again.

Wow that's nasty Baka better talaga regular OCI with semi synthetic or dino oil lang.

May nakapag try na ba ng AutoRx on your Toyotas? Worked wonders on a 10 year old Civic's varnish. Parang ginamitan ng polish yung engine.

[cta2]

They are a bit quiet and assuring me that there is nothing to pay... That's the reason I want a documented report on their end... Requested for computerized report and letter head of Toyota... Don't like verbal or just hand written on scratch paper... Wait and see muna ako...

Just doing my own research for probable causes

[sirkosero]

id ask them to replace the car under warranty. or at the very least replace the engine. dont bother yourself with repairing the engine.

if they dont want to replace the engine, escalate to toyota philippines. not sure if jing delgado is still there but you can escalate to her office to get fast resolution.

Toyota has to diagnose the engine muna, then try to repair it. if unrepairable, then they have to replace the engine na siguro.

cta2, ano service record mo with toyota? on time naman parati yung change oil mo? also, after opening the valve cover, what did they find out? you have to ask them na agad. kasi may makikita na agad sila pag bukas ng valve cover. i suggest go to toyota and pasok ka sa work shop nila to see what is happening. you have to visit the casa everyday if possible.

mukhang maganda yung autoRX.

pero you can also try using Caltex Delo multigrade oil. its a diesel oil, but also S rated, so pwede sa gas engine. high detergency so it will also clean the internal of your engine.

Thanks for all the concern and possible leads...

I do have my own connections with Toyota :-) and already a long time client of the same Casa :-)

The 1st confirmed problem is the Oil Pump, and that my valves were not "in-tune"... Made me think baka kaya may oil sludge (for the others) because oil pump is not working... for now I cant believe oil sludge is my culprit because my car is relatively new... and regularly serviced (no miss at all).

Parts are already with them... so they will install within 2 days and reevaluate again... I really hope it will be back to normal!

why aren't the valves "in tune"? you never opened the engine. you didnt do any modifications naman. you should ask them to explain everything. business is business. your connection might not tell you everything.


HowStuffWorks "Engine Valve Train and Ignition Systems"

the camshaft controls the movement of the valves.

[cta2]

Thanks for the How stuff works... actually appreciated it!

A friend of mine suspects that its my timing belt (which was mentioned in your link)... Im not really a mechanic so I just want it fix and the assurance that my car is reliable.

I do have to admit I have a heavy foot but my car is matic so it should not matter...

Nag ka mild stroke kotse ko (in my own layman's thoughts, will also give you an idea my age) and I guess it affected the valves...

Ang alam ko:
1. car was still normal even when the warning light was on
2. car went straight to casa, no other side trip
3. Oil Level is normal
4. No Overheat

Will give them time to isolate the problem... I just want to arm myself with some knowledge :-)

Thanks for all your inputs!
