timing chain

I have a '06 4.0L that has 106K that I have to pull the heads (coolant leak), my question is if I'm going to have it apart should I replace the timing gear also (benefit v cost)?

I have an '03 Explorer, 143,000 miles, and it makes a clattering noise that rises with rpm's. No codes. I tried removing the belt, but the noise is still there. The timing is rock steady at both the #1 and #4 cylinders. What is going on? I don't want to drive it until I figure it...

I have a 2003 Explorer which I bought new. The explorer had about 66,000 miles on it when it began to make a rattle in January 2013. A mechanic told me he suspected the timing chains were bad and to sell it while it was still running. 2 weeks later the explorer died on the side of the road...

4.0 SOHC V6 '97 Ford Explorer 305,284 miles. Loud Clicking noise started about a week ago. Let my mechanic drive it, but no noise. A few days later, extremely loud clicking that got louder with RPMs. (I was on a road trip at this point) On my way home the car died.(thankfully just a few miles...

So i just bought a 97 explorer and there is a click noise in the engine. I was told that is was a timing chain problem. Also i had the codes scanned and looked them up in the manual and they said i have cylinders 2 and 3 misfiring. What does that mean? Is that just a spark plug problem...

hello, I recently bought a 92 explorer with 300K miles, the trans was rebuilt aprox. 5K ago and as far as I know the engine is extremely old. Usually when i go up hills or accelerate it will rattle between 2 and 3 thousand rpm. However it will rattle at other rpms and speeds occasionally. Im...

Hey guys, I have a 02 Explorer with the 4.6 (Romeo) motor. It has a right timing chain noise. Either the tensioner or guide either way Im going to replace everything. I see that theres a little opening in the timing cover from where the chain has been hitting it. I've done some...

I have read many times on this forum that the timing chain never needs to be replaced, that it lasts the life of the engine. Well, I am calling bull. I had several problems that wouldn't go away and after I changed out the timing chain its like I have a new engine. I had a couple of...

I just finished the front timing chains, plugs, and wires on my 2002 Explorer last night. I had the famous rattle from about 2,200 to 2,800 RPM and it started in January at about 128,000 miles. I fully expected to see the main chain flopping around and bits of plastic in the oil pan and...

I have a 2002 XLT 4x4 4.0L with about 128,000 miles and the timing chain rattle between 2,200 and 2,800 RPM started about 6 weeks ago. I pulled the right cam cover last week and the right cam chain and guides seem to be okay for now. I am preparing to replace all of the front timing chain...

I've been sucking info from this forum for a long time. Now that I'm doing a big job I thought I'd give a little back. My 03 ex has been making some ticking sounds in the front of the engine, from info I've gathered on these forums I've determined that it is most likely timing chain related...

I have a 2002 4.0L Explorer. It recently had a broken timing chain tensioner on the rear timing chain. Being out of work, and broke and all, and this being my only transpo, my friends and I pulled the engine and replaced the timing chain & gears on the back. We used the timing chain...

I recently started noticing the pinging and rattling sounds that are prevalent with timing chain issues on my '98 Explorer with the 4.0 V6 SOHC engine. Asked our regular mechanic about it and he suggested we take it to a dealership. Dropped it off at 8 this morning at the local dealer and got...

I have a 2001 explorer sport that has 143,000 miles and had only 2 owners before me. The previous owner didn't take very good care of the vehicle and so ive had my work cut out for me from shocks, brakes, plugs and wires, new tires and wheel bearings and so on but overall the vehicle is in good...

I have a 2003 Explorer with the 4.0L V6. It has about 115K miles on it. It sounds terrible when started cold, with a very loud rattle that I was told is the timing chain. The idle is a bit rough, but it gets better when warm. It doesn't sound perfect when warm, but much better than when its...

Hope someone out there can answer a couple of questions regarding my parent's Explorer. The vehicle is a 2005 Explorer with a 4.0L engine. A couple of weeks ago my mom was driving down their road when she heard a loud noise. She thought she had hit a pothole, but the vehicle continued to...

Can anyone in the North West or North Wales recommend a quality garage who can do timing chain replacements? I am aware of one in Aylesbury and one in Newport which advertise but how good are they? They're also a long way away. It seems to be a common fault and there must be somewhere up this...

I had my 98 die while driving and am pretty sure that the timing chain went on it. Is there any major damage done to the engine, and how do I re time the engine? I guess the question I am asking is there a tool that i can retime the engine with and is it worth it? I would greatly...

What's up everybody. Got a sweet new issue with my spoder. I took it to a place a year or so ago for a chattering noise and they said that they replaced the front timing tensioner along with the oil pump. The noise did stop for a while then it came back. For the longest time my engine has made...

O'kay this may be a bit long winded, but I want to give you all the information I have. About two weeks ago my '01 sport trac wouldn't start. Leaving work I turned the key and heard one big click then nothing. On the second try it started right up no problems ran just fine. Next morning we go...
