Timing belt problems. Bad luck?

[selmerguy]

Well I was on a trip from Missouri to Virginia and my car died in Evansville In. Anyway I stored it there and bought a truck to tow it back. I finally got to tearing it apart and to my supprise the belt was still intacked. Kind of.... There was a section of the belt where the teeth were missing by the crank sproket. I have never seen a belt fail this way without something ceasing up. Everything is in perfect order and the cams are pins up in time. I might have bent the valves but I am tempeted to throw a new belt on there just to see if I got lucky, before I have to tear it all apart. With the cams in the position that they are in I might have a shot. Anyone else have a belt that just lost the teeth in a small area? I will post pics later.

the same thing happend to me while I was in stop and go traffic on the fwy. I bent some valves cause the crank is moving and the cams were not. what I did was replace the belt and did a compresion test. If one the the cylinders is way low then you got bent valves.

Purchase a new belt since you will need one anyway, put it on and turn the motor over by hand to see if it actually does turn over, without any problems (struggles or metal on metal sounds). If you can do this, then you can run a compression test and see where your numbers are at and go from there.

Or u can just take off the valve cover and see if any rocker arms have fallen if so then u got bent valves.

Same exact thing happened to mr. my belt shredded a little. like what he said above pull off your valve cover and see if any rocker arms fell off thats what i did. Good luck bro

same thing happened to me. a few of the teeth were stripped off by the crank. i tried turning it over and it was ok so i put a new belt on and it was fine.

Got some time today to look at it and I am not very happy. All the rockers were off on the intake side. The exhaust side seems fine. I just had a valve job done about 6000 miles ago. Can I just buy new intake valves and have them swapped in at a machine shop? How much should this cost? I will remove the head and all. I am not to confortable messing with valves myself.

Why? Replacing the valves is less complicated then removing and installing a head. This should be a cinch for you. As long as you have the tool, or be like me and make you're own.

Really? I will look into this. Know any good write-ups?

It isn't as easy as just swapping valves, at least in my experience it wasn't. I recommend having a reputable shop do it for you.

Here is the tool that I made. However, it seems none of the pics are loading. Must be an server issue still.

Um.... yea, it pretty much is. If you have a valve spring compressor and a drill it's pretty easy.

 

[selmerguy]

Would this work for the removal and installiation of the valves?

[19Eclipse90]

Yes, that should work just fine.

 

[selmerguy]

I wont have to ghetto rig that one will I?

 

[19Eclipse90]

No, it looks like it will work pretty simply. The longer 'grabbers' will grab a lower part on the spring while the shorter 'grabbers' will push down the spring retainer. Then you get a magnet or pliers and get the two c-clips (little c-shaped metal pieces) out and your valve should slide ride out the bottom.

Well I pulled the head and while I was pulling I thought about the valves I ordered. I ordered 8 intake valves when I needed 8 exhaust valves. Wow I must have been drunk when I ordered these things. Oh well anyone need some intake valves?.....

Same exact thing happened to me too once....put on a new belt and I was fine.

Does not look like that compressor is going to work. With the valves being bent the springs have to much tension on them to fit the arms in on them. I might have a shop replace the 8 valves. Should not cos to much. It looks like the compressor will work on straight valves.
