When is the timing chain of a 2007 1.5 4x4 daihatsu terios changed?


Timing chains do not need changed until they break or get so loose that they jump a tooth on the chain. But if you have a timing belt instead of a timing chain, it does need to be changed before it breaks. Replace the timing belt every 60,000 miles. Severe engine damage will occur if you do not replace the timing belt every 60,000 miles.

We are looking into buying a 2007 Buick Lucerne CXL v-6 with 89,000 miles. What type issues are we looking at? I noticed it has a timing chain, when do they need to be changed, if it breaks what type of...


A very nice comfortable automobile:) No concerns with timing belts...no other major concerns...they hold resale value well don't they:) At 89,000 miles you early maintenance concerns will be have the brakes been replaced...have the front rear struts been replaced? Tranny fluid filter serviced yet? Also should replace plugs and wires by 100,000, also look at wear on serpentine belt...coolant serviced? These are minor concerns, but will definitely affect your enjoyment of this premium Buick:)

Are the V6 engines Free spinning?


Hi Lukegerny,
No,the V6 engine is not free spinning. If the timing chain breaks, leaving the valves open as the piston moves through its travel,there will be damage to the valves.How much damage will depend on speed of engine and length of time it ran. You can perform a leak down test to check the condition of the pistons and valves. It will tell you if the valves are not sealing,without having to take it apart. Thanks,Chuck.

TIMING CHAIN CHANGE


hyundai recommends replacing the belt every 60,000 miles or 48 mos and this is an "interference" engine which means if the belt breaks, it will cause internal engine damage. happy holidays

Do I need to replace a timing belt or chaing?


Timing belt maintenance is extremely important! All Neon models utilize an interference-type, non-free-wheeling engine. If the timing belt breaks, the valves in the cylinder head may strike the pistons, causing potentially serious (also time-consuming and expensive) engine damage. The recommended replacement interval for the timing belt is 102,000 miles (163,000km), or sooner.

I'm not sure what model your Jag is but, for the XL8+ there is a TSB/Recalls (Technical Service Bulletin) for:
NOISE DURING START UP - INSTALL REVISED TIMING CHAIN TENSIONERS:
Some vehicles within the above VIN range may experience a rattling noise when the engine is started. This noise may be caused by the secondary timing chain tensioners. Research has shown that a noise can originate at the chain tensioners to cause a resonance in another part of the engine.
A revised, spring assisted, secondary timing chain tensioner has been introduced to eliminate this concern, commencing at engine No. 98102106XX. Introductory VINs are not yet available. In case of a customer complaint, the revised tensioners may be installed on earlier V8 engines.
But then again, I'm not sure exactly of your model, if you get back to me with the exact model, I can check for any TSB/Recalls for you :)

Will a timing chain/belt cause your car to stall out when driving it and not allow it to start up after it stalls?


I had a timing chain problem, It made a noise for about 3 years and it decided to break last May, the engine just totally stopped. My 99 cavalier had 164,000 miles on it. My friend and I found out the the cavalier 2.2 eng. has a non interfer timing chain. so when my timing chain broke it didn't cause any damage.

Timing Chain 2003 Subaru Outback LL Bean Edition


I would definently Replace the timeing chain before it breaks. because if it does break when its running it will cause catasrophic failure. such as bending valves and possibly breaking a piston. every so many miles your chain should be replaced as with the belts. it is a safty precaution. A little money spent now will save you a lot later.
hope this is what you were looking for.
