timing belt tensioner

[93talon760]

Does anyone know if u have a bad timing belt tensioner . Would that cause the camshaft pulleys to be off three teeth

It could be the cause. if it's not keeping tension on the timing belt, the belt can easily jump teeth and ruin the valves.

The first belt I did I didn't compress the hydraulic tensioner right and 1500 miles later jumped 5 teeth on my intake cam and took out all the intake valves.so make sure you do it right...take your time!

Cool thanks for the info.

If are going to be changing it out, change EVERYTHING else with it.

Ya it is I just rebuilt the motor everything is new except the tensioner.

Interesting... makes me want to go pull the cover and rotate to make sure the teeth are all lined up. Other than a rough idle it seems to be fine... but I'm only 200 miles from changing the belt (and a year)

Well, glad I came into this thread... I decided to pop the top and rotate to see how lined up they still were, but didn't get that far. Watch for a new question thread staring the picture below... Looks like I'll get to change another timing belt...

same thing happen to me. buy a new tensioner and also a new timing belt.
a hyundai elantra 4g63 auto tensioner will work if you wana save money.

The kevlar belt is a nice upgrade as well. I replaced my timing belt with kevlar, replaced all the idlers and also put a manual tensioner on the car all at the same time. Well worth the money as i've had no problems whatsoever.

It's caused by the wrong bolt in the oil pan,the one that comes thru and near the oil pump sprocket. Someone put the a long one in,instead of a short one. Same thing happened to me,thanks to the PO. Take off the timing cover and you can see it almost touch the belt. Either replace it with a shorter size or take it off and grind it down,and of course replace the belt and you'll be good to go.

I've been told it's that bolt, but when I spin by hand it all looks fine, and I can't see anything interfering

Strange. My bolt wasn't exactly rubbing the belt all the time but after start-up you could see it 'slapping' it. Wish I would have taken pictures of it. And,at first I didn't think any bolts were touching it either,but the closest to the crank sprocket was the culprit,if I remember right.
