remember 1 thing..dont confuse cam timing with ignition timing also if the belt or chain has alignment dots or marks on it ..it can be put on backwards and still line up marks correctly but but in a different position making the cam timming off i have done it and seen it done before like an old chevy when you put timming gear set on you line up the 2 dots alot of people think that is tdc and they set up ignition and go to start it and get pops and bangs well thats because the the install dots are actully 180 degrees out from tdc so you remove the distributor and turn it 180 deg. and now she starts right up i think you have 1 of these cams a tooth off or your using marks incorectly or belt or chain is backwards making dots align in different postion appearing correct
honda DOHC and SOHC motors have "zero tolerance" motors, this means if they "jump timing" they need to be inspected for head/valve damage, have this done before spending money on replacing the timing belt
sence the belt broke more than likely yes it did damaged the valves. but to make sure call the dealer service dept. and ask if it a zero degree talerance motor. if they say yes then you need to have your cyl. head reworked. hope this helps
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)
a stripped group of cogs on timming belt is most likely ur problem,a new timming belt may not solve ur problem,this is a interference engine ,u may have bent vavles,install timming belt and if it runs,and runs smooth and got plenty of power,then u will be ok
There is no room for error...... Zero clearance. If off one tooth it can and will bend valves. if you are one that just feels the need to get alittle dirty or just can't pay for the service, then get out your Haynes out and turn to .....Tune up, and look at replacing timming belt. Get a cam gear tool that locks them into place so as that they will not move when u have them lined up. make sure they are lined up with marks as said in book. then make sure crank as well as all marks are lined up acordingly. make sure belt marks are lined up with everything. i would reccomend using a volvo belt though cause it will have all the marks on it.However other company's make good quality belts also at a fraction of the price. So it is really up to you.
Good thing when doing timming belt is to also change out your timming belt tensioner. YES do this it will save you a engine in the long run. it is a moving part that will go bad, it will freeze up and snap timming belt. rip out teeth in thebelt and bend valves. So as a gen rule...When you change timming belt, Change belt tensioner at same time since you cant just change tensioner without changing or getting timming belt off. Remember to use your HAYNES. It is your friend and will save you money in the long run. Good luck... Hope this helps you.
Get a T belt from toyota. It has 3 white lines on
it and and arrow mark. 2 lines are solid and one is broken. Put the
arrow facing away from the engine. The cam gears have a dot punched
into them near a certain tooth. This is where the solid white lines
will line up with. The crank gear will have a dot also. It will line up
at 90 degrees from the top, towards the front of the car. This is where
the broken line will match up with. With the belt installed with all
lines on their proper dots and arrow away from the engine, you valve
timming is correct. Of course you need to remove and compress the tensioner also. I assume you know this already since you didn't ask.
