What Should I DO???

superTD · Post by **superTD** » Tue Jul 10, 2007 1:21 am

First, I want to thank all the valuable comments and advise on my last topic, they were really helpful. My car is Daewoo 2000 Lanos with about 90K, there is a loud ODD noise from near T-belt area. Today I took the car to the nearest car shop (Walts), and they took an hour to find out what the problem is, and after they start my car, the noise became worse and louder (I don't know what they did), and they shut it down right away. After that, they told me that the timing belt teeth are bad. They gave me an estimate of $700 US dollars to fix it (Timing belt, water pump, etc). BUT they don't know if valves are bent or not. If valves are bent, it will cost me additional $1500. They told me that 75% chance the valves are good since the engine was shut down while was running with bad noise, but they won't be able to find out if valves are bent without replacing a new T-belt and water pump. HERE is the problem, I don't mind spending $700 to fix it, but if they find bent valves, it's gonna cost me extra $1500, which is definitely not worth it. Honestly, I do NOT want to gamble it.

I live in western Washington State. I tried to look for someone who is familiar with daewoo, but just couldn't find one, and the dealership is a little bit far from my home. I have been driving this car for almost 4 years, and have been taking very good care of it. I am thinking to sell this car without fixing it, but don't know how much I can get it back.

you know i did all the work on mine myself the timing belt is not that hard to do neither is the water pump if you need i can give you step by step instructions i got from this forum as well from a chilton....chilton import 1998-2002 covers the timing belt replacement when changing the cylinder head

if you can ready and you have a jack and few tools you can do it yourself and save a ton of cash...i dont know what other people think but i would change ur belt and see if the sound goes away....everything i have heard is if 1 valve is bent on these cars they wont run...also hear valves bend in sets of 2

i advise against doing anything other than replacing the tining belt NOW... it could snap at any time and you could be facing 1500USD head work at a blink of an eye.

you can simply take off the head when you are doing the T belt and put it upside down and fill the compartments with gas... if it leaks through the intake/exhaust ports then you got bent valves but if not (and i hope that it doesn't) then just but it back on and enjoy the ride.

trying to drive the car or start the engine now is very very dangerous... you have pushed your luck way to far with the 90k miles and taking more chances now is just asking for trouble.

P.S: 750USD fot a T belt job?? i am seriously thinking of moving to USA and open a garage for daewoos... i can see car service is very profitable their.

tell them to do a compression test. they can make sure that there are no bent valves that way. they can also do it with out starting the engine, although they will have to turn it over by hand. if the engine passes the compression test, you have no bent valves and all you need is a belt, tensioner, idler and water pump. good luck

comp. test with almost dead T belt... not a good idea... atleast not to me plus it will mean more labour to disassemble every thing again

you only have to put the guage input in the spark plug hole, and as i said, turn the engine by hand, if there isnt any damage you will be able to stop the engine befor any thing goes wrong. what im saying is if the engine turns over, slowly tunr it over by hand, if you hear or feal ANY thing strange, stop. it only takes 2 min to take the spark plugs out and put them back in, so im not sure of what you mean by disasembling things again. but thats jsut what i would do.

Question .....

Will the valves interfere with the pistons if the belt is tight but some teeth are chewed off ?
If the engine wont run or is running very rough? I am thinking yes.
But ! I am thinking no, if the engine is running ok this means enough belt teeth must be available to keep everything synchronized. ?

Who knows for certain ?

Not me !

well i had to replace two bent valves on mine and when it happened it sounded like a black cat firework had popped inside my engine. another thing i found out if you have bent valves when you try turning the crank by hand it will only go so far an stop as if some one is pushing against you, don't force it past it or you will F***k shit up worse than it is. just try it in the opposite direction and if you get the same result going the opposite direction then you definitely have some bent valves. you can try the same procedure with the cams. it only cost me $500 mainly because all they changed was the F'd up valves cleaned it up and put new lifters and seals. but it works fine.

Before rotating the engine and risk damage would checking that the timing marks line up show whether or not the belt has moved or likely to be valve damage?

the how to only covers the 1.6 engine the 2.0 the concept is simmilar but not the same.
what i would do is find TDC on cilender 1 then a minimal turn of 8 degrees clockwise should
line up all the markings.
