my timing belt wont stay on the edge of the cam gears closest to the block. it slides back to the outer edge and rubs against the valve cover. if it helps i have a prelude with a b20a5 in it. i tried putting it back on the inside edge but when i start the car it goes right back out to the edge. any help would be appreciated.

 

Adjust your tensioner.

 

i have the tensioner tight as it will go.

 

Thats why it is sliding to the outside edge of your cam gears... The tensioner is not supposed to be that tight, in fact it can actually do irreversable damage to your head and also wear your main bearings pre-maturely.

If you need help, send me a PM.

 

trust hatch man, he is a good guy

 

i figured it out. the thin metal piece with holes in it that goes between the crank pulley and the crank gear was missing. i put it back on and it did fine. thanks for the suggestions and the information anyway though.

 

all the tension on the tensioner is from the spring pulling it back. i didnt put any more than that cause i was affraid it would put tention on the belt and cause it to wear faster and snap.

 

ok good...

When you said it was as tight as it would go I got concerned...
Yes it will cause problems if the belt is too tight.

 

The tensioner bearing is probably worn, or the bracket is bent. Something is making one of the pulleys crooked such that it is making the belt walk..

 

i was waiting for you to chime in fabrikate. if i trust anybody on this site its you. you seem to know your shit good. but i got it straight. the tensioner or pulleys arent bent.
