Ford - Explorer :: 2003 SOHC - Timing Chain Cover Gasket Change
I have a 2003 Eddie Bauer explorer with the 4.0L SOHC . I have a coolant leak from the passenger side that is not a water pump issue.
When removing the timing chain cover with the engine in the car, do I need to remove any accessories ( power steering , alternator etc. ) or their brackets?
Tiguan :: 2.0l TSI Timing Chain Tensioner Failure
I have an '09 Tiguan that recently began to start hard. Two days ago, it refused to start and hasn't started since. It cranks and cranks but to no avail. I disconnected the fuel line at the first hard piece on the front side of the head. The primer pump when activated pours gas out of the line for about 5-8 seconds.
I also pulled the coil packs off and verified there is spark on them. I scanned the car with vcds and came up with nothing other than a couple voltage codes (battery is low at this point from cranking and is bulged and showing yellow in the spot window).
Tonight I borrowed the perfectly fine battery from my B6 and attempted to start it. No codes whatsoever and yet it still refused to run.
Golf/GTI VI :: Timing Chain Tensioner Failure - What To Upgrade
I hear it's a problem on the Mk VI. Is there anything you can do or upgrade to eliminate the problem ... especially considering that it goes out of warranty after 5 years.
View 12 RepliesTiguan :: Timing Chain Tensioner Causing Catastrophic Failure
I have been reading about all these horrific cases about the tensioner just giving and causing catastrophic failure. Without all the maintenance records VWoA is reluctant to support 100% even if you're still within the powertrain warranty. I understand these 20+ cases are a small population out of the entire group, but I don't want to risk being another statistical point for this topic. Just ordered the HS Tuning kit and the two snap on tools.

View 2 RepliesFord - Explorer :: 1999 5.0 - Change Timing Gears And Chain After How Many Miles?
There was a time Ford when used a nylon toothed timing chain gear on the camshaft. Over time this got brittle and started to break into pieces. The rule of thumb at our household was to change these at about 100k miles.
I think that was a "302" thing and all "5.0" engines have all metal gears? I have no reason to open up our '99 Explorer's 5.0 with 180,000 miles. But, I will change the timing chain if it should be done.
Ford - Explorer :: 2003 - Valve Cover Oil Leak / Timing Chain Rattling
My 2003' Explorer XLT (4.0L V6) has an oil leak. I tracked it down to the passenger side, rear, bolt head on the valve cover (back by firewall). I took it to a guy who replaced the valve cover gaskets, but it is still leaking. He claimed when he had the cover off he looked for any cracks on it, but did not see any at the time.
Anyways, I was searching around and found several explorers leaking in or around the same area of the valve cover. And it turned out that there issue stemmed from bad timing chain guides, causing the valve cover to crack.
I do notice that on a cold start, I hear a rattling when I first start it up. It rattles for maybe that first 1-2 seconds when starting. Is this my timing chain rattling around? If that is the case, how much this could set a guy back on repairs?
I guess I don't know whether to just replace the valve cover, or if I should dig into it to see if the real issue is the timing chain guides/tensioner. Mileage is approximately 121,000....
Ford F-150 (2004-2008) :: Timing Chain Replacement?
I have a new style 2004 F150 XLT supercrew with a 4.6. Well, I just hit 300,00 miles earlier this week. The truck has performed pretty much flawlessly over the years (and still does). I've replaced front hubs, IWE's, brakes, fluids, etc, but have NEVER opened up the engine. Is it time to replace the timing chain?
First thought is ,yes, like 50,000 miles ago, but... It has some dents and dings and the rust is getting to it. There is 300,000 on the transmission also... Virtually no residual value- If it strands me on the road, it's time for a new truck.
On the other hand, it only burns a little over a quart at 3000 mile change intervals, the transmission seems strong. I just shampooed the cloth interior and detailed it. The thing looks great from the vantage point of the steering wheel.
No engine issues at all- no rattling, etc.
Timing-belts - Belts - Volkswagen - Touareg :: 2004 - Timing Chain Malfunction At 90,000 Miles Common?
I brought my 2004 VW Touareg V6(83k miles) to the dealer for a recall on the ignition call and much to my surprise, was presented with a diagnosis of a $6,000 problem! The dealer told me that the computer read some codes which say that the timing chain is stretched and needs to be replaced. They said it will take 4-5 days and should be done asap so it doesn't "go out", because if it does, it's an even more expensive problem. I took the car to another VW repair shop and they asked me if I heard any noised when I start it cold (like pebbles in a bucket). I have not had any problems like that at all, so they said I shouldn't worry until I start getting symptoms. They also said there is no recommended point (like 90,000 miles) when VW recommends the change, so it really shouldn't be a common problem. I want to do the right thing, but I don't want to rush into an expensive repair if it isn't necessary.
View 1 RepliesFord F-150 (2004-2008) :: Passenger Side Timing Chain Guide Badly Damaged - Replacement?
So working on a 2005 F150 with a 5.4. Started off as a phaser replacement. Turn out the passenger side timing chain guide was badly damaged. Front timing chain cover came off and replaced the guide and phaser. Got everything back together and it ran rough. Pulled the front timing cover off and the passenger side was off a tooth.
Retimed that passenger side and also replaced the tensioner because the seal on the old tensioner wasn't the best. Now rotating the engine, i noticed the tensioner pushes then retracts. Seems like a vacuum is created pulling the plunger in, but not entirely sure. Only the passenger side does this, not the drivers side.
Worried about putting the front cover and valve covers on, buttoning everything together and having it skip another tooth because of slack in the chain. Any fix for it or reason why it does it?
Toyota - Avalon :: 2004 - When To Replace Timing Chain
I'm told by my dealer that I must replace the timing chain by 100,000 miles. I've also been told by others who've driven multiple vehicles over 250K miles that they've never replaced a timing chain on any of their vehicles. Who's right in this case?

View 13 RepliesFord - Explorer :: How To Adjust Idle Speed On 4.0 SOHC
I have tried playing with screw that controls throttle plate it does work at first allowing to reach 1200 rpm at idle however after stopping car and starting again it does go down to ~600rpm again like computer adjusts it back to desired level. There's also **** on Idle valve however turning it does nothing.
Is there way to reprogram computer to make 1200 a desired RPM?
Like try this yourself reach about 1200 rpm and then hold your leg still not looking at the rpm your once you hold it for a while it goes down to normal rpm, only way to hold constant 1200 RPM is to play with gas pedal.
I want to raise RPM to avoid misfire.

I did notice when turning the key the dash lights come on then half a second they go out. interior lights, and 12v outlet work but no headlights. Any issue other than the obvious corroded terminals or loose terminal wires?
View 2 RepliesFord - Explorer :: 2006 4.0 SOHC - Small Vacuum Leak
I'm having a little bit of trouble finding the cause of a minor problem on my 06 Explorer with the 4.0 V6 engine. When the engine is running cold at idle, it runs a bit rough and idle speed is high as well. When fully warm, the engine runs and idles fine. I hooked up a scan tool and there are no pending or stored codes. The live data looks ok except the long term fuel trim which is at about +10% on both banks during idle, indicating a lean condition. Short term fuel is right around zero. The MAF and TPS values seem to respond fine when applying steady throttle.
So I assume there must be a fairly small vacuum leak somewhere that the PCM is able to compensate for since the long term is only at 10. I didn't see anything obviously wrong, the vacuum lines look fine along the passenger side near the firewall. I sprayed a bit of throttle cleaner along the hoses, intake manifold and gasket area, but could not spot any vacuum leaks. Any other common areas to check for leaks on the 4.0 V6? Perhaps there is something I am missing?
Ford Ranger / B-Series :: Timing Chain Cover Leak
My truck has had this annoying tendency to drink coolant. I believe I took care of it by replacing the thermostat gasket. Not so, it drinks about a quart every 50 miles - so quite a bit really.
Finally bit the bullet and took it to the dealer so that they could figure out where the coolant was going.
Answer I got back was - timing cover gasket, water pump, lower radiator hose.
The water pump appears to be good, its just the gasket that's bad. So my question is - how significant is the timing chain cover leak? Poking around online it appears to be reasonably common, but sounds very expensive. The dealer indicated it would be 2 days work minimum.
