Question about 1999 Daewoo Lanos
Hi just replaced the head gasket on my Daewoo 1999 Lanos. I have it back together as far as the timming belt. However, the timming marks on the cams do not line up perfect. I can turn the cams to make them line up but it starts to open the valves when I do.
I am waiting for a tool to adjust the water pump and a new auto adjuster for the timing belt but need to find out about the timming marks issue. I don't want to bend any valves.
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)

If this is a single overhead cam, possibly A15SMS (engine type):
If you have everything stripped down and can see the crank shaft gear, you will notice an arrow stamped into one of the gear teeth.
this arrow must point towards the bottom, you will notice a mark (notch) cut into the housing, line the arrow on the gear with this notch.
remove the four 10mm bolts that secure the top cover of the timing belt, gently open the cover (not removing it) to see the Cam Gear. You will not be able to remove the cover because of the design.
The Cam Gear should have a line stamped into one of its teeth, this should be pointing up and towards the top. On the inner cover you will notice a notch in the casing, line both up together if it is not already.
You can check the following if unsure:
Remove # 1 spark plug (nearest the Cam Belt) and place a long screwdriver in the hole carefully to feel the piston is at the top, #2 and 3 will be down and the last one #4 at the distributor end will also be up.
Remove the rocker cover and you should see the Cam loabes on #1 piston free, (no pressure on the cam shaft) meaning the valves are closed.
