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 9 RepliesJust purchased a 2002 Camry for my son to drive to school. The car has 275,000 highway miles on it The car was well maintained by the previous owner. I have heard that the timing chain should last about 300,000 miles. However, the owner's manual does not mention any replacement interval. Since the cars mileage is approaching 300k, I'm wondering if the chain needs to be replaced. The engine runs great. However, I do hear a bit of a rattle from the timing chain pully area. I replaced the valve cover gasket and inspected the chain but didn't notice anything unusual. I have mainly driven import cars with timing belts and not sure if this rattling noise is normal for a Toyota with a chain or an early sign of needing replacement.
View 5 RepliesI have a 2003 Toyota Corolla with a leaking timing chain tensioner. I was able to locate a procedure for replacing the tensioner but it didn't say whether the no. 1 cylinder had to be @ TDC or not. What is the proper procedure for this repair?
View 1 RepliesI 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 RepliesI 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.
I was thinking about checking out the above vehicle at my local dealer (Chevrolet). They're asking 15.9k and it has 57k miles. I need to know if it has a timing belt or a timing chain and how reliable is the engine/transmission.
View 1 RepliesI have a quick question, when a timing chain breaks on a gli does it cause damage to the engine(like mess up the piston and valves) need to know ASAP.
View 1 RepliesReplacing the timing chains and tensioners on an SOHC Explorer, only to have the tensioners fail again after only a few thousand miles? I'm a pretty experienced back yard mechanic and have rebuilt several engines over the years with great results, but this one has me stumped. The only part of the instructions I did not do was to remove the valve springs, but everything was lined up as it should have been using the special tools required to set the timing. I really like the truck, but don't know if it's worth fixing if this is just going to happen again.
View 3 RepliesSo 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?
Just got 2005 screw fx4. Seemed to run ok 115000 mi.Had exhaust leak,I put on 3" cat back on. Then I noticed tapping at front of the engine.Turns out tim. chain guides are broken. looks like very common prob after reading many forum/threads. Anyway got timing chain kit, phasers, selinoids. Truck runs and sounds great.But so far had truck back 2weeks stalled 2x at idle.What next??

View 6 RepliesOn Feb 2015 I had this oil leak developing around the timing chain cover/ oil pressure plug and so i replaced the oil pressure sensor and clean the area and though problem solved...
Fast forward today and the weeping has redeveloped and has gotten larger than last time , its only a weeping issue no visible oil droplet leaks, anyways I took a mirror and when probing around and found the leak origin from the rusty looking timing chain tensioner...that what i think it is.
My question is should I just remove and replace the Rubber O-ring on it or should I just replace the entire timing tensioner unit with a new one, my original timing chain tensioner is sitting at 85k miles. The O-ring is free (i have a kit) and i can do it right now or a New Timing chain tensioner w/ new O-ring is around $20 bucks but i cannot verify the part number ...
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.
I read for a few second at start up ok . Have it checked : [URL] ...
I will be opening up the case in next few days. Chain still on holding by a few teeth. Metal wedge between teeth and chain.
I have a 2006 Honda CRV with 145,000 miles on it. It has been giving me warning lights for about 10 weeks. My mechanic discovered that it is burning oil, which he says all old cars do. But the lights continued. He put the computer on it and says that I need a new timing chain and it will cots $1,100.00. He also says he's not 100% sure that this will stop the lights. I don't want to sink that kind of money into the car if it won't correct the problem. The lights that come on are the check engine light, the VSA light and the triangle light. They do not come on all of the time. Maybe 3 time a week but they go off if I stop the car and re start it.
View 19 RepliesMy neighbor have a neglected 1995 Dodge Ram with the 3.9L V6. This engine is called a "Magnum" but I have to say it is pretty gutless overall. Anyway, it has the famous clatter caused by the timing chain tapping against the timing cover. Every one of these from this time period sounds like this and I understand it is a common problem. Is this a critical problem or not? I understand it can be fixed by replacing it with a newer style timing set with a tensioner. If this won't cause damage, I say leave it alone as the noise is just a minor annoyance. I was just in as far as the water pump and was tempted to tackle it but figured it could wait.

View 7 RepliesExperiencing a really bad rattle after changing the oil? It sounds like the chain tensioners are losing pressure during the oil change.
View 11 RepliesI just replaced the timing chain and water pump on my 1999 K1500 5.7L. After spending several evenings and a few early mornings working on it, I get everything back together and go to start it up. It starts then immediately dies. After double checking that the CKP sensor, two plugs on breather, and a/c and alternator wires (these are all that I unplugged) are connected I try in one more time before coming in to work today.
Timing chain was installed with No. 1 at TDC and mark on cam at 12 o'clock position as stated in the Haynes manual for the truck. I did not remove or even touch the distributor since replacing the intake gaskets ~3 years ago. Will check to see if any codes are showing in the morning when I have my laptop at home.
Changing timing chain tensioner? Mine is making the rattling noise on startup. Tried searching one internet for any DIY's out there. Haven't really found any good ones.
View 7 RepliesMy 2007 3.3l SF timing chain cover is leaking.It has 93,000Kms and is still covered by warranty.The Dealer said it was a 17hr break down job to do.
I am wondering if there are things I should get done/replaced when they open the engine up. I had asked at the dealer if there were other parts that should be replaced at this time, but was told that there was not.
