Who has racked up the most miles.....??

[phantomcobra]

tune1552, you misunderstand. It was a joke. I have just passed 74 miles NOT 74,000. I've had the car less than a week brand spanking new off the new car dealer lot.

[wille]

had my 05 for about 9 months 21k miles

[aveo81]

my 04 aveo has 67 000km
on it and its making a sound like the timing bearing or teh ohc bearing is on its way out dose taht sound right to you it sounds like a lawn mower when it is cold and it somewhat correctifies its self when it warms up makes me think its a bearing and its coming from the timing housing...and iv had a considerable amount of decreased hp since this noise started if any insite you can either leave it here or email it to me at daddy2oz@hotmail.com

[aveo81]

i have also had my ecu fine tuned and it did a considerable amount of difference

[mikedudley17]

where or how did u get ur ecu tuned? did u do it for gas mileage or more power? did u buy a chip or did a mechanic do it for u? just curious.

Definitely get it looked at! Had similar noises at 38K miles and it was the timing belt failing. It was replaced under warranty.

Follow the advice of another poster here -- DO NOT exceed 60K miles with this car without replacing the timing belt -- it seems to be a problem area and you could seriously damage the valves/pistons.

Well my '04 aveo just cost me 1600 dollars. The timing belt went and the values bent. Got a value job done and asked my mechanic when the maintenance on the belt was required. The owner's manual says 60,000. My car has 93,000.I did some research and California law requires timing belts to last up to 105,000 miles. It looks like GM went cheap and did not upgrade the belts. My car was checked the last time I bought it in for service and my mechanic said all my belts were fine. I am thinking about filing a class action lawsuit against GM. This could be a huge problem for aveo owners. I commute over 100 miles per day that's the reason for the high mileage.

I think you're lucky you made it that far! Have gone back into Daewoo forums and one of the major problems they had (including the 1.6L Ecotec engine) was timing belt/tensioner failure, many times before 60K miles.

Seems that issue wasn't corrected for the Aveo -- have heard of many failures already. 60K miles should be seen as the maximum between changes, not a mere suggestion.

Actually the Aveo has an E-TEC II. It has nothing to do the 1.6L Ecotec you would fined in Opels.

Also the Ecotecs 2.0L 2.2L and 2.4L in the Cobalts and GM’s other American cars don’t use timing belts, they have timing chains.

Some of the Mitsubishi engines must have the timing belt replaced or the same disaster can happen busting pistons and bending connecting rods and valve stems. You have to take the radiator and water pump off to get to the timing belt and you best go ahead and replace the water pump while you're at it. It's an eight hour job for a skilled Mitsubishi technician and runs around $800. and has to be done every 60K miles. I was on the verge of buying a Mitsi SUV but when I found it had 80K and the timing belt had not been replaced I backed out of the deal.

Correct - I meant E-TEC II, which was virtually the same engine used in the Daewoo Lanos. Owners had a lot of problems with timing belts failing due to the water pump leaking and affecting the belt tensioners. From what I've heard from owners with 50,000+ miles (and my own experience), it would be EXTREMELY wise to follow the belt replacement schedule rigorously on the Aveo.

I'm not planning on exceeding 50K between replacements since the first one was shot well before that.

From Wikipedia:

D-TEC

D-TEC was an older variant if Family 1 SOHC engine licensed by Daewoo Motors for their range of Opel-derived cars such as Daewoo Espero and Daewoo Nexia. These engines are built exclusively at Bupyeong engine plant. They feature valvetrain driven by toothed belt, in a DOHC configuration for most versions, and aluminum cylinder head.

• 1.3 L SOHC - Daewoo Lanos
• 1.5 L SOHC - Daewoo Lanos, Daewoo Nexia
• 1.6 L SOHC - Daewoo Nexia
• 1.6 L DOHC - Daewoo Nexia, Daewoo Espero, Daewoo Lanos

[edit]

E-TEC II

Updated version of D-TEC. Most models feature Euro III-compliancy, and 1.4 L and 1.6 L DOHC versions employ variable intake geometry.

• 1.4 L SOHC - European Chevrolet Kalos/Chevrolet Aveo
• 1.5 L SOHC, Euro II - Asian, Middle Eastern and South African versions Chevrolet Lacetti, Chevrolet Nubira and Chevrolet Aveo, CKD kits of Aveo assembled by ZAZ
• 1.4 L DOHC - European Chevrolet Kalos/Chevrolet Aveo, Chevrolet Lacetti and Chevrolet Nubira
• L91, 1.6 L - 103 hp and 107 ft.lbf of torque - U.S. version of Chevrolet Aveo, European Chevrolet Lacetti and Chevrolet Nubira

Higher-displacement versions of D-TEC and E-TEC II are indeed Family II engines built by Holden.

Ok I just wanted to make sure that everybody knew that the Aveo is the only GM vehicle that has these problems.

you should try to find more people who have had similar timing belt related issues and go in on gm. the more people you have the better your chances would be of accomplishing anything. but i do think for the time being everyone should really be cautious with the belts and check 'em periodically.

hi everyone, i have 04 hatch aveo, (yellow ) i have 105K Miles, still running!!

[Huney1]

"mickha2 hi everyone, i have 04 hatch aveo, (yellow ) i have 105K Miles, still running!!" That's nice, but you're living on borrowed time and when the timing belt breaks and bends push rods and valves and busts a piston your smile will quickly turn to a big frown. Notice I didn't say "IF" it will break, . .. I said "WHEN" it breaks and if you don't have it changed you can bet your sweet pippy it WILL break.

My neighbors daughter has a KIA and the timing belt wasn't replaced, it broke and total engine disaster and repair would have been so expensive they got a rebuilt engine and put in it.
