timing help....
I have a 01 mustang gt 4.6 that I bought to resell. I had a lil bit of noise from the timing. I took It apart and found the guides were tore up. Trying to do a cheap quick fix I replaced them, everything looked good so I put it all back together. Still had a noise, tore it apart again notice a lil slack in the chain. I read that the tensioners are common to go bad on these motors. I bought new tensioners a and put them in, I spun the motor around a few times and there's still slack in the chain but it jumps from side to side as the motor turns. Just before I replace more then I need to or run into another problem I want to make sure what the problem is. Bad tensioners? Stretched chain? Or something else I'm not seeing. Thanks in advance for all comments and advice..

The tensioners are jumping because they have no oil pressure. I give the cam bolt a slight turn counter-clockwise once the chain is on to pre-load it. As soon as the engine fires up the tensioner will fill with oil and it should be fine so long as you did everything properly.
