I'm working on a 2002 ford explore, doing a timing belt job. After replacing both timing chains it is stilling rattling. There is slack in all 3 chains. Please does anyone know what I can do to fix this?

Well, sense all ya did was tell me the model and nothing about what motor it is.. I'm gonna say that the guides are broken, pins for the guides broke out the block, tensioners are broke, cam actuator is broke, your bangging PTV. ya bent valves, it's a rod knock. Hope some of that helps.

lil more info and can maybe do something for ya.

Haha. Sorry about that. Its the V6 4.0. At work and trying to figure this out. But finally I found the solution. The left cam was 180 out. My boss, who helped me reassemble the engine, put it in upside down. Finally the engine is going back in, and I am confident that this will fix it.

Oh damn... I hope thats not a interference motor, I can't remember...

but why were your replacing chains?? was it for the rattle (original complaint?) Thats not going to fix the rattle problem if thats all you did.

The 4.0 S.U.C.K. is an interference motor, IIRC. Hopefully, you got lucky and didn't bang all the valves on that side. If not, Monte is right. You may have bad tensioners. Those engines are known for that problem.

I actually replaced the chains, the hydraulic tensioners, and all the guides. The engine is in and is running smooth as glass. Thanks guys.
