Black Sludge and Toyota/Lexus

[crazy_boy]

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.

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!

ok, update us nalang. so that we can give you some advice too.


pero at 12,000km, it shouldn't be the timing belt nor the valves. they have an OBD scanner and you can ask them to give you the error codes so that you have an idea of what is wrong with your car.

BTW, what do you mean by "mild stroke"?

just to document...

My car arrived last Friday and everything seems back to normal.

I still dont have the technical report from the "Plant" but I have the service or job order

replaced was:
1. OIL PUMP ASSEMBLY (the whole set)
2. SEAL PACKING

To access the oil pump assembly, they had to open the valve cover according to them.

I was charged with the motor oil 2K++

I think everything is fair... I still feel better off than a flooded car if thats any consolation... I do have experience with other brands... like fixing something they dont know how to fix... I dont like guesswork... at least with my personal experience, they took responsibility of warranty, no questions asked...

I still think Toyota is in my top 3 choices (though not anymore 1)

BTW - Oil Pump Malfunction is their reason for the warning light... they can not explain why it malfunctioned
