hi all
just changed the head on my EL I6. used an AU gasket, etc. just fired it up and it runs well, but revving it just off idle causes a horrible rattle from the timing chain. when removing the head i did not touch the timing chain tensioner, so it would have sprung all the way out. however when re-assembling, i removed the tensioner, cleaned it, and put it in as per the procedure in the manual. so i'm thinking i either don't know what i'm doing when re-setting the tensioner, or i've somehow broken a guide. is it possible to over-tension the chain by releasing the tensioner too much? it looks to me like there are multiple points you can release the tensioner to, but i don't understand how it'd work properly in anything but the fully released spot? can anyone offer any advice or help. i've done a fair bit of searching and am hoping i haven't done something bad enough to cease the aux shaft or something like that meaning the engine is a throw away! |

Scroll down a bit and there should be pics on the tensioner and how to set it. As far as I know, the tensioner should be fully unlocked, that way it can push the piston into the guide. When putting the tensioner back in, you need to make sure that the tensioner sleeve is locked into the piston. Once all is in, the tensioner sleeve needs to be unlocked from the piston causing the spring to push the piston towards the guide and the sleeve towards the tensioner screw. Also make sure the guide sits in the groove of the piston. phong =P~

thanks mate, i've seen your thread already and i've done everything youv'e said. all i can think is i haven't unlocked it far enough somehow - but it doesn't seem to want to turn any further.

When the assembly is in the locked position and inside the shaft, you should be able to push it in and turn it (not sure in which direction). It should release itself fully into the released state. There shouldn't be any levels of release as far as I know...unless it is stuck somewhere. Also...forgot to mention. The tensioner is hydraulic controlled, so if you have just started the car, then the tensioner hasn't gotten enough oil yet. Give it some time and it should go away. Mine lasted a day or so. phong =P~

hahaha. I point the finger at that then. Just don't rev it. let it idle for a bit and see how things go, goes away after a while phong =P~

sure its the chain?
is it a rattle or a tick? your HLA's will probably also need to refill with oil, they make a ticking/tapping noise

Same thing Happened to me.
I basically gave up and went to Ford and got a new tension assembly. This fixed the problem. It may have been slightly damaged when I removed it?? Cheers Dazza |

i've had it running for a few minutes now, it's still the same.
i took the rocker cover off and double checked the guides. they do not appear to be broken. the chain doesn't have much play in it at all. might try shimming the tensioner a little - i'm running out of ideas

I have had this exact issue for 2 years now - since I fitted an XR6 Tickford head. I've tried a new timing chain tensioner, no change. I tried shimming the tensioner a bit no change. I've had mades set the tensioner, and my old boy try no change.
I know it's the chain making the noise, as I've run the engine with the rocker cover off and bought a mechanics stethescope and you can clearly tell it's the chain. My solution was just to ignore it, have been for 2 years now. Since that time I fitted a supercharger and have put 9psi of boost through it and thrashed the car and nothing gone wrong yet (people do ask what the noise is though). |
