Re: Replaced timing belt not running right
The Lanos engine are an interference engine. If you have bent valves, remove a plug wire one at a time and see if there is no change in the idle. My guess, one of them isn't going to change anything. That would be the cylinder that has the bent valves in. I had a Lanos in my shop with a broken timing belt and the head had several bent valves. I wouldn't be surprised at all if you also have bent valves.

yes it is quite possible that valves are bent if the cam belt broke or teeth stripped off of old belt, which unfortuneately means removing the cylinder head and getting it repaired (valves replaced and possibly guides) see some of my other posts for cam belt timming marks locations etc...
depending what motor is in your vehicle twin cam or single?
and if its twin cam you usually need cam locking tool for cam gears.
hi, just letting you know my timing belt just went on my daewoo lanos. unfortunately it seems in a daewoo lanos that when the timing belt goes, it can do damage to one of the valves. mine is in at the mechanics and i am still hoping that it hasnt done any damage. i was also told that if you have replaced the timing belt and the car still wont start it has definitely done damage to a valve. sorry to give you the bad news!!
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)
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.
Are you sure your timing belt is on right? If you're out one tooth, it's gonna run like ****, and if it's not firing at all on one cyllinder, you're going to wash down the cyllinder walls (with gas while you're driving) and have engine failure. 400 K ? You might make it. Won't do your engine any good.
As Long as You ABSOLUTLY POSITIVE the Timing is Dead on , And Plyg WIRES are Not Crossed Then Hate to tell you It Must Have Taped a valve. Start it up and Let it Idle Take The Plug wires OFF 1 By 1 And Listen for NO DIFFERANCE in the IDLE the ones that Make NO Differance are the Bad Cylinders for LUCKS SAKE Check the Gap on the Spark Plug of Effected Cylinders and as I said Make sure the Spark Plug Wires are not Crossed. Hope it turns Out Good For Ya I Have Been there done that on My Personal Car I Feel your Worrie. Please Show some Care and Rate Me For This Solution Although its Not Potentualy the Best Outcome, Again I Hope for YOU Its A OOps as Aposed to a OUCH for ya, Easy, RejakWilson
