Timing chain tensioner replaced(need help)
i heard a rattling noise on my lincoln ls with similar engine to s type. I opened the valve cover and decided to replace the secondary chain tensioner. after installing everything, the secondary chain looked lose but then i tried turing crank with a ratched, on some turns the chain is tight then it loosens up and then its tight again, the tensioner spring goes up and down, so i am not sure whats going on, i just finished everything and started the car and i can still hear the rubbing sound
here is the video of my car http://www.youtube.com/user/kassanov.../0/LwMxBc1aDzk

bottom side of the tensioner was worn out , but i don't understand is that the after installing the new tensioner, the chain feels lose from the top side of the tensioner but when i turn the crank it tightens up, looks like a play in the exhaust cam as i turn those counterclockwise the chain tightens up. i dont know what is wrong, i doubt the chain is stretched

I would NOT fabricate something from any hardware store. I would contact several Jaguar repair shops and see if a short term loan can be arranged for the proper tools. You will destroy your engine if it's not correct. The Jaguar and Lincoln engines are interference designs. This means that if the cams are not in correct time the valves will hit the pistons. You have a 32 valve V-8 don't risk this!!!

hey tbird 6, okay i listened both valve covers with stethoscope and the sound is comming from the one i replaced. i read ur article its really good, when i put the exhaust sprocket on the cam, the chain feels tight but when i tighten the sprocket bolt the chain losens up, so i tried turning the crank with wrench the chain tighens up and then losens up, so what exactly did u do to cure this, i see u mentioned in ur article that thats what u experienced as well,

hi tbird I know u can help me out here, i opened the driver side valve cover, found that the tensioner is installed opposite to the other side which i did last week, i mean the spring side was on the top but when i opened the right side of the car before it was installed inverted, i rotated the crank, on some turns the bottom chain tightens up and then losens up a little , but since the slack is felt on the bottom on this side compared to the side i opened up before slack was on the top since the spring part of the tensioner was installed on the bottom side. I want to know when u did urs were the tensioners installed opposite to each other or what. i really need ur help buddy i am so clost to finish, give me ur email add i can send u the picture and the video i made
