timing belt out a tooth!

no you have to remove the belt from the cam pully and alighn the cam pully to its correct location then refit the belt.

ahh, stupid question.. its all becoming alot clearer now :thumbsup:
so when your engine is at TDC and..
1. the timing belt is aligned properly (not out a tooth, all the dots lined up) & it is not too tight or too loose
2. the timing isnt out (been checked with timing light)
3. and the cam pulley is lined up
the prob should be solved..

if i do all this and it still is not solved, then either i got problems from when the belt snapped, or i have to look elsewhere.. i.e. dizzy, cat converter etc

thanks for all the help ECU-MAN & Wynode, i really appreciate it.. sorry for all the Q's, just trying to get my head around it and trying to learn off it :)

i hope i can fix it myself.. good learning experience

no problems man, this is what the forum is for, to ask questions and learn.

you must set the ignition timming after you change the valve timming. dont just leave it.

if you think you have the valve timming right, and it still plays up, do a wet and dry compression test, to test is the valves are ok.

the timing belt may have one to many teeth.. buy a new one and count the teeth.

good point garett, thanks for pointing it out.. i somehow have a feeling the belt that was put in my car is not the best/correct one for my car.. ill check that out when i have it apart and can access the belt..

it should say it in a manual, might have to check it out at school or invest in a manual for my car, it would be very handy right about now

if it had to many teeth, it would make the gear set non hunting, meaning eventually the valve timming will get that far out it would bend valves, or just not run at all, ( only would take seconds of engine running )

ahh k, well i can cross that one off the list, ive learnt heaps from this thread :D

hey guys, checked my valve timing today. When at TDC, the cam pulley was not lined up! my timing belt was out a tooth as suspected. The mechanic had lined up the belt according to the timing mark instead of the TDC mark. I moved the belt a tooth over, but its still out about half a tooth?!?! If i move it over another tooth it would be out half a tooth the other way! its strange, it is a honda belt they put in, wether its for my model civic i dont know.

Also, when i was doing my timing after i put it all back together, in the manual it says to bridge the 2-connector near the ECU in the kicker panel, but the book said to do it with diff coloured wires to what i actually have, hope i did it correctly, if someone can give us a hand with this it would be a huge help, i could find 2 connectors, one was a 3-connector the other a 2-connector, so i did the 2-connector. The timing was way off and the dizzy cant adjust anymore, it runs out of room before the timing marks can line up perfectly (the dizzy only has a little room for retarding/advancing)

After doing all this, i took my car for a bit of a test drive, it seems to have improved a fair bit and i hadnt heard any pinging. I went up a bit of a hill to put it under a bit of load and drove it fairly hard and under the pressure it started pinging again, was fine afterwards though when it was under less load.

So basically it has improved greatly, but not 100%, if anyone has any help for me on why my belt would be out half a tooth or any advice on how to correctly do my timing please help!!!!

cheers :thumbsup:

Did you make sure your car warmed up before checking the timing with a timing light?

hmm, only let it idle for say, about 3 mins, while i set up the light and undid the dizzy bolts.. that should be warmed up enough id think.. i really think this connector im supposed to bridge could be messing me up, either that or because the belt still not 100% perfect

you should let your engine warm till the thermo fans come on at least twice before adjusting the timming.

then short the short connector and set the timming.

I dont think you have your valve timming out half a tooth, its either out one way or to the other, the slack on the belt that can make it look out half a tooth.

i think it may be the slack then (i hope!)...
my teachers said it definately isnt out another tooth, it was hard to turn the engine to exactly TDC and it could be slightly off TDC when the marks look straight, like reading vernier calipers.. :P

maybe ive got it all under control now and need to let my car warm up and redo the timing.. i wonder if that could cause slight pinging..

ill try the timing again.. im pretty sure the dizzy should sit in the middle of its path, it is completely against one side and still out..

do u know what would happen if i was bridging the wrong short connector? could that be the problem..

btw ECU-MAN, i ended up doing it myself with a little help from the teachers (we're doing ignition systems at TAFE so they let me do it at school) thanks heaps for the help, it made things so much easier, and made it easier to explain certain things to the teachers, i appreciate it :thumbsup:

it wasnt very difficult at all.. i just wasnt too confident
