SOURCE: had a cambelt break on

Its because your pistons on 1&4 are up top that is why your bent valves got bent you are doing exactly the same thing so turn the crank back 15degrees position your cam and reset your crank,it seems to me you may be out of your depth lets hope not or it may be expensive

SOURCE: Motor g16A 16V, Borken cam belt, has it bent the valves ?

Do not attempt to start the engine under any circumstances until you have carried out a few tests. IF you dont have valve damage replacing the belt and trying to start the engine could cause serious further damage.
Replace the belt and make sure the timing is perfect, you might need to rock the pistons back and forth via the crank pulley in order to fit the belt if the pistons come into contact with a valve or two. Once you have the belt fitted and the timing right remove the spark plugs and slowly turn the engine over by hand, not with the starter motor. With the valve cover removed and with someone turning the engine by hand you should be able to see any valves that are not operating correctly. If any thing doesn't look right then you will have to investigate further by removing the cylinder head.

SOURCE: 2004 aveo timing belt broke, all valves bent

just go to any junk yard and find a used deawoo lanos and pull the head if timing belt was not broke, if it looks good, its a exact fit 100%, no special tools needed, just normal wrench set and torqe wrench. after head is installed, get a gates timing belt only.

SOURCE: 1999 escort zx2 timing belt broke

The ZX2 Zetec is a non-interference engine. This means the valves are not capable of touching the pistons at any time. If your belt breaks, there will not be any valve damage. There are reliefs cut into the top of the pistons that allow clearance for the valves if the belt breaks. Most engines are interference and will cause several hundred or even thousands of dollars of damage when a timing belt breaks. Most shop manuals list the ZX2 as interference but it is not. Many people seek out this how-to because a mechanic has informed them that they have valve damage and quoted a repair price over $1000.

If my timing belt broke while trying to start my 2006 galant but it never cranked over is my motor damaged ?


Yes -- the motor is identified as an interference engine and that means in the event of belt failure there will be damaged valves from hitting the pistons. IT is a matter of removing the head and replacing the bent valves . There should be not other damage to the engine . The job in an accredited shop will be around $1000 dollars which should include valves -head gasket kit-new belt- idlers -hydraulic tensioner and cam and crank seals and labour

Does the timeing belt have to be on for the crank to turn the cam when instilling the timeing belt?


Are you replacing a broken timing belt? Or are you replacing a belt because it's due by miles? If the belt is broken, i strongly suggest inspecting for bent valves. Daewoo is notorious for bending all valves and breaking valve guides in the cylinder head when the timing belt breaks. The broken belt is also common.

The timing belt broke while I was driving. I replaced it and set the timing according to specs. it will crank but not turn over. What could cause this


if the starter is cranking but the motor isn't turning over you have something wrong, remove the timing cover and crank the motor over, see whats turning and what isn't, both the cam and crankshaft should be turning over,, if it is, and by meaning its not turning over you mean its not starting you could have it 180 degrees out, check the number one plug to see if its on the compression stroke, which would place the rotor at the number one position inside the distributer cap,, if its pointing away from it, you have the timing set wrong. and need to reline the timing belt to the correct place

How to replace a broken timing belt for a 1998 daewoo lanos?? Would there be any head damage?


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?

Renault laguna 1.9 valve change


If the cam belt popped you may not need to pull the head.. See if all you valves come to full height when you turn the cam with a wrench. If they do, you lucked out and none are bent. Change the timing belt and rotate the crank and cam together once everything is in time, and if you can, do a compression test. That will expose any bent vales. If you have compression. recheck your timing belt settings and button it up. Good Luck, Ned

Low idle/stalling with new timing belt on 1999 Honda CR-v


The engine is a twin cam, one of the cams is not lined up properly. Obiviously the car was running fine before the t/belt replacement, Something the mechanic did is the cause. It is very common with this engine for this to happen. The timing belt covers need to be removed, and the cam gear alignment needs to be checked. Both cam gears have an "UP" mark at the top, and slash marks that should be level with the head when on TDC. If all the marks are lined up, I would have them perform a cylinder leakdown check to see if there are any bent valves. Another way to check the valves is to remove the valve cover and check for very loose valve adjustment. If any valves are bent they won't close all the way causing a gap in the adjustment, and poor performance. Unfortunately the dealership should have found this right away. If I remember correctly the rear cam is off one tooth, retarding the cam timing.
Let me know what they find, Honda Al
