timing

2006 4x4 with 165K miles. Developed loud engine rattle recently, though still runs okay (for now, anyway). After searching the forums it sounds like it is likely timing chain(s) related. Others have found pieces of a tensioner when pulling the (presumed lower) oil pan. I think I'll start...

New here, but not new to Fords and wrenching on them. My son has an '06 Eddie Bauer with the 4.0. 174K miles. He bought it with a brand new transmission in it, and the motor seemingly ran well. After a while, he said it was rattling a lot. Doh. (Didn't listen to me when he bought it about...

I’m not sure what to do with my Explorer because of the timing chain rattle at startup. It’s an 07 4.0 advance trac, I just passed 160,000 miles and the start up rattle is progressively getting worse. It takes longer to go away especially on a cold day. The rest of the engine seems to be in good...

Hi all. I rather stupidly trusted a UK member who begged me to order all of the OE cam guide parts necessary to rebuild his 2000 4.0 Sohc explorer since most of it is obsolete now. I work for a Ford dealer, so I get a decent discount. Usually our parts dept has a strict "pay up front" policy...

Replaced chains, guides, tensioners , waterpump and crankshaft pin. Sounded ok at first, but rattling again.... changed oil twice with flush, thinking plugged up oil screen. Next getting tool to check oil pressure. It's got to be the main chain tensioner that is powered by the oil pressure...

Can anyone tell me how many times the camshaft syncroniser rotates for every revolution of crankshaft harmonic balancer? If I'm not mistaken is it 2 times? This would be on a 4.0 V6 OHV (NON-SOHC) I feel stupid. I rebuilt this 97 ranger engine and the timing chain was set at 6 and 12...

Hey everyone new to the ownership of a sport trac, I have a 2004 sport trac 4.0 v6 I was doing routine maintenance and changed the upper front timing chain tensioner, didn't know it needs to be primed and put on with a very thin washer, put it on and leaked super hard from there, took it out...

I am in the currently waiting on more FORD OEM parts. I remove a 2003 ford 4.0 SOHC motor and it had a timing chain loose as a two dollar. So i had no choice but to fix that issue. Due to my using the wrong bolt to press off the crankshaft pulley.It got stuck in side the crankshaft pulley and I...

So I had the rattle a couple of days ago, got a tow home as the last time I hsd it I just carried on driving and ended up smashing the engine. I ordered new tensioners and the timing kit in anticipation (which I will keep in case as engine is ~200,000 miles). 8 hours' deconstruction later...

Hi I'm Charlie and I'm looking to vent (Lol) Nah just wanting to talk to some other Ford owners about the Timing Chain Issues in the 4.0 and The Tips and Tricks to make it better.

One day while going down the road, my 94 ford explorer 4.0 died. It started right up again, and ran fine for a while until sputtering and choking out at speed. Now you can't go any faster than a creep, otherwise it bogs down and even with full throttle it doesn't do much. I replaced the coil...

I replaced the left head timing chain tensioner on my Sport Trac, but I didn't realize that it was not threading into the head straight. I removed it and put it in straight with a new washer, and tightened it to the correct torque, my torque wrench could easily be out of calibration, because...

I've had my 1999 Explorer 4.0 SOHC professionally rebuilt with the stipulation that I would have to install the timing components myself - which I did using the OTC timing kit and a new timing kit with balance shaft tensioner and chain from Evergreen (which is apparently not worth buying) and...

I have a RWD, 2001 ford explorer sport, with the 4.0 SOHC engine, that has about 195k miles on what I assume is the original trans and engine. I inherited the truck from my late mother. I have put the last 15-20k miles on it with minor issues but now I have a nice clear rattle at cold start from...

2004 Ford Explorer V6 4.0 K series XLT 2 Wheel Drive. 146K and never been serviced. Got it off a guy about a month ago. Drove it ran rich with a bunch of fuel issues. Fixed all the issues and got it cleared ready for smog. Few days after, TIMING TENSIONER goes bad and caused the REAR GUIDE to...

2003 Explorer XLT 4.0 AWD So I had what I figured was the typical timing chain rattle on the v6 explorer. Was loud at idle and also above 2500 rpm. So I did an oil change and also dropped the pan, what I found was nothing, no metal shavings, no plastic guide pieces, nothing, just used oil. I...

I'm having a very faint rattle/chattering noise suspected to be around the left side of the engine more towards the back, but it could possible be in the front. Definitely more prominent on the left (passenger) side. It doesn't sound severe enough to be a timing chain, and it doesn't sound...

How difficult is the timing chain to replace

So, I'm having some pretty severe and sudden issues with it. Haven't had any issues before with noise from the timing set, until the other day while driving through a neighborhood. Started hearing clicking coming from the front driver's side wheel well while driving. Thought it would have been...

My truck has a clicking sound that sounds like a spark plug now. I took it for a spin and when put the pedal to the metal the engine misses and it just revs. Normal when just going like 25-30 mph. I Believe my engine is out of time bc I replaced the timing belt the other day and accidentally...

Anybody install auxiliary shaft (jackshaft) bearings with the engine still installed (and trans removed, of course)?? Are the front and rear bearings different on a 2002 4.0 sohc?

I bought a clean 2002 Explorer 4x4 XLT to fix up. The engine sounded like a diesel and had no oil pressure at idle after warming up. I began by researching threads here and changing out upper timing chain tensioners. I also removed lower oil pan and cleaned out metal shavings and one metal ear...

Back again with yet another question that's probably been answered. 1997 Explorer E.B. V8 AWD has obtained a noticeable engine shake to it. I noticed it a few weeks ago while working on installing a new stereo. I had it idling and everything was running smooth then all of sudden it started...

Im fixing the timing chain on a 2006 4.0 thinking of doing just guides already have 1 new tensioner the one next ti thermostat housing. I already removed intake, alt, bracket, ps bracket. What else is involved? Seems to me like water pump, timing chain/engine front plate, valve covers...

We have an '03 with 128K on it, went through a toll gate and no acceleration after, ran like crap. Made it to next exit, stalled and wouldn't restart. Rode flat bed of shame home. No breathing through engine 15# back pressure, cats totally clogged. Replaced Y-pipe and cats. Now runs, but...
