Hello,

I bought one Avensis 1.8l VVTI (1ZZ-FE I4) made in 2006, 4-speed automatic, everything ok but I have a doubt on mileague.
The inside engine parts have a brown colour (dipstick also get this colour on surface). Is not slum but only colour redish-brown.
Freshly new cars have gray steel colour but from oil heated on them gets changed (you may see through oil cap also this colour on steel pieces)
Engine runs flawless, it shows 128.000 Km on bord but i suspect is has over 200.000 Km
Is there a certain fact to check in order to get the mileague ?
How many kilometers this engine supports? ( until rebuild)
Ex-owner service book does not exists. I bought this car via a friend, it looks perfectly and runs also ok.
I changed the oil which was overused (black but still greasy), no oil consumption so far, full fluid service planned.

Thank you,
BR
Grigore

Without service history logs, you will only be guessing. They could have been using cheap oil or not changing it as often as necessary. It is less likely they have swapped the cluster or otherwise have more mileage than listed.

The discoloration is quite typical from using non-synthetic oil over extended periods, as you have witnessed by the condition of the oil. It is not an indication of higher than indicated odometer reading... You can your actual oil early, and use synthetic oil which has much greater cleaning abilities.

Toyota engines have been known to last a while before requiring a rebuild as long as maintenance is done. As far as I know, Toyota claims the 1zzfe doesn't require a tune-up (major?) until at least 100,000 miles. Unless poor maintenance has been done. You can always pull the spark plugs and check the diodes for wear and over use. Could be trouble if there is caked oil on the diode?

Diodes? You mean the spark plug's center and ground electrodes... You can also measure their gaps, which increases with wear from its original 1.1mm.

My bad. I must have been thinking of something else.
