I had a nasty 'rattle' in the front of my engine on an older truck of mine (around 190,000 miles) and it was the timing chain. The guide for the chain had broken and caused my timing chain to rub against the front cover and start eating it's way out (the rattle). Got it fixed, new chain and replaced the front cover as well and everything is fine. Good luck, I hope this helps.

Engine on my 2004 Ford explorer just stopped running. i purchased this vehicle new and regularly had it serviced at 3,000 miles. It hacle only has 71,000 miles on it. After approximately a weeks time i...

First thing first, was there a noise in the engine area, that sounded like a rattling, or marbles rolling around in it? One of the timing chain guides might have broken, and the pistons will hit the valves and ruin them. Over time, (not millage) the timing guides will get bridle and crack/break causing this problem.We have owned 8 (1994, 1996, 1997, 2-1998, 1-1999, 2001, (presently has 211,000, 2003, 165,000 miles) Ford Explorers total, and 4 of them have over 300,000 miles, and sold one (1994) to a fire fighter with almost 800,000 miles on it,( with the complete maintenance records since new) and he gave it to his daughter, going to school, and she drove it another 100,000 last I heard,(2008). I also have bought and repaired/sold the newer "E" engine code, (8th digit in VIN number) because of this problem, so I have owned a few with the "timing chain/giude problems.You can opt to have the heads and timing chains and guides replaced, a used engine installed, or request a local shop to install a re-manufactured engine. $5-6,000 seems high, but depending on your area, might be a good price. If not, I might be interested in buying your vehicle, before you scrap it. avenger_craig@yahoo Put Explorer in Posting line title.

Problems with 07 tundra, engine light on, won't turn over completely without pumping gas pedal. Told it needs timing chain replaced

Timing chain controls the valve timing and causes running issues. It sounds like the chain and or chain guides are bad and you should NOT drive it that way as you can cause much more damage. Get it fixed and you should be fine. If it is a high mile car have them do a complete inspection of the vehicle before you spend any more money so you know if there are more issues.

I have a 2002 chevy trail blazer and there is a rattle ,vibration coming from the head and they told me it could be the timing chain, miles on vehicule 117,000

Is it vibrating while in gear at a stop light? If this is it, it's your engine or tranny mounts. Use genuine GM mounts as aftermarkets tend to crush too much sending your engine back to the same height as the old ones. Timing chain? Doubtful it's the timing chain, our timing chains are virtually bullet proof and with 117k on it, your engine is just breaking in. Many of us TB owners have well over 200k on it and don't know anyone that has changed it.

I have my Dad's old 1997 Nissan Maxima GXE ( he bought it brand new and always took it to Nissan dealership for everything)' It now has 295000 miles on it, but recently started making a loud rattling sound...

if your chain becomes loose it will become very noisy and should be replaced since most nissans are interference engines which means lots of money for a new engine

Clicking sound under hood - possible timing chain

timing chain life span varies, it depends on what type of driving u do, for instance heavy on the throttle wears ythem out faster from the streaching this causes, but at 160,000 miles the noise u are hearing is likely a loose timing chain, replace it before it comes apart and damages the engine. This job is not for the home mechanic, it requires special tools and a high degree of skill and a factory service manual is a must.

2002 corolla (now 91000 miles) makes rattling sound

Thats good that you are getting a second opinion. A Toyota dealer will be able to check it and see what the noise may be. See what they come up with. I dont think a worn timing chain or guides would cause a low oil pressure problem. But, if it does indeed have low oil pressure, that is a serious problem.

Ford tdci 2.4 diesel engine as fitted to 1994 LTI TX2 taxi. Constantly replacing timing chain and tensioner. Five replacement chains and tensioners in 140,000 miles. Engine is serviced every 6000 miles....

cant help the only ford 2.4 engine diesel i know of is the york engine and that has a timing belt not a chain.Sounds like you could be a bit fastidious because all timing chains show wear on the tensioner,causing a bit of a rattle but unlike a belt it will not break just get a bit noisey,answer to that is to turn the radio up a bit

2003 Nissan Maxima Timing Chain

You can wait its just fine, However if you ever start to notice oil leaking from front cover, then you will need to change. If there is no loss in power feel sluggish especially on take off, Its almost impossible for these type of chains to break. So enjoy until the wheel fall good luck
