my timing belt is pretty loose, its rattling against the plastic cover, (at least im pretty sure thats what the rattle is), to tighten it i can adjust the tensioner pulley, but the timing wont screw up right? i dont need the #1 piston at top dead center? or should i just get a new belt, or bring it somewhere?

You could adjust tension without getting out of timing, tension until you could twist 1/2 turn the belt, if is brittle or old looking, replace it.

You need to adjust the tensioner to tighten the belt up. However, if you're belt had enough slack to hit the timing belt cover, I'd think that your engine would be way out of time or not running at all. Are you 100% that it's the timing belt?

Re: Timing Belt is loose, help me out... (Glenn J)

yes i know i have to tighten the tensioner, my question was do i have to worry about timing issues or do i just tighten? also it is very loose, theres at least 1.5" of play in the belt, and im pretty sure thats the rattle, i pushed the timing belt and its loose enough to hit the plastic cover, but my timing isnt off i dont think, car is runnin pretty good, any suggestions now?

If your timing was off, your car would be running poorly and throwing a check engine light. If you're not getting either of those, tighten up the tensioner and you should be all set. Check the belt while you're at it though. Make sure the "teeth" on the belt are OK.

The belt runs from the crank to int to cam then to the tensioner, tightening the tensioner won't effect timing unless you have slack between those 3 gears. All of your slack needs to be at the tensioner ie back side of the engine. If you have slack on the front side you need to get the slack out without letting the gears rotate before you tighten things up.

Get your hands on Bentley and go thru the timing belt R&R steps...line up timing marks and see if everything lines up (cam, crank, distirbutor timing marks) if so then you're one lucky dude since belt that loose should have jumped a tooth or two for sure! Tighten up tensioner pulley untill you can just twist belt 90 degrees midway between cam and intermediate shaft gears, then torque pulley bolt to 43 ft lbs to keep it tight. Start engine listen to belt....if it howls like a dog with a sore tooth...you got it too tight. Loosen pulley bolt again and release a little tension, retorque and listen to belt runnin again....howl gone...replace timing cover and your good to go! http://****************.com/smile/emthup.gif

Re: Timing Belt is loose, help me out... (spitpilot)

to check it just twist it, if it is under 90 degrees, to tight, over to loose, is 90 just right....
Make sure you rotate the engine TWICE manually and then check.
And make sure you rotate it FORWARD not backwards..

If it is losoe, you WILL need to retime it, unless it is only a very little bit loose.
I had that rattle to, it was 6 teeth that fell off and would spin there
