HOW WE CHANGE TIMMING BELT IN LANOS CARS - 2000 Daewoo Lanos

both the single cam and twin cam engines use the teeth on the crank pulley for crankshaft sensor which is bolted in bracket attached to block near oil pressure switch, hopefully you didnt dent(bent) teeth on crank pulley from dropping it or putting pulley down a bit roughly because they bend really eazy.
also is the crank pulley bolted up in correct position?
is the timming belt tension correct from when you did cam belt?
if tension wrong or timming out by a tooth it will set crank sensor codes, even possibly cam sensor codes and if you get timming out more than 3 teeth either way(advanced or ********) you will bend valves.

you are out a tooth or two.engine must have moved a bit when you had it apart

yes not a free spinning motor

Check the condition of the tensioner and pulleys, a bearing may be bad in those items

there is a special tool to hold gears in correct place on some of these models, but you can hold one cam at a time with a spanner then feed belt on exhaust cam then inlet cam gear
get someone to hold gears in place while you feed belt on.
the inlet cam is more prone to turn off mark more than exhaust.
if you have tensioner that needs retaining pin in when installing
you fit belt while aligning timming marks
fit tensioner as last spot to feed belt on with retaining pin in adjuster
get correct tension on belt by turning water pump so that you can flex (turn) belt 90 degrees only just while using finger and thumb
tighten water pump check flex
check all timing marks are correct
remove retaining pin from auto tensioner
turn motor over a couple of turns by hand observing tensioner arrow should hover around V mark and that all timing marks align up again(after one complete turn)

• was washer put back on the crank correctly? Is there spacers or gromits that hold the timming cover on? Sometime I run car before I put all excesserys back on just to see that problem...

yes they bend valves
head needs to come off and valves will need replacing
this can be repaired
timming belts on these should be replaced every 60,000km

timming marks on cams face each other 3 and 9 o clock crank mark at about 6 o clock mark in cover and sump auto adjuster arrow should be in v mark to set this requires turning water pump by loosening water pump bolts slightly be warned some times this causes pump o ring seal to leak if turning.

First remove head and fix the bent valves. I have worked at a Daewoo dealer. People would buy the belt and come right back to get valves and gaskets. Daewoo timing belts must be replaced every 60,000 miles.

No.....you do not have to change the timing chain due to being parked....it is wise though to follow manufactuers specs on WHEN to change it.

There is nothing wrong with your timing chain.
