This particular motor is dependable.If there are timing chain issues you may experience noise due do worn guides. I have never experienced a timing chain failure on one of these engines
if valve timing off due to worn timing chain engine wont start.if you suspect timing chain need replacing if you hear slapping noises best replace timing chain quick as possible if you keep driving timing chain will break cause engine damage.
This 2.2 Liter engine uses a Timing chain, timing chains are never replaced unless the engine is being overhauled, there is no periodic replacement required like a Timing belt. Engines that use chains are much more durable than those that use belts and last longer per dollar spent on maintenance costs. I wish I had a dollar for every ruined engine due to a failed rubber timing belt.
when the chain got older it got loose due to the tensions so it will make your car`s engine sounds louder but if the chain cut your engine will be dead and in some engines the piston will hit the valve destroy each other so don`t underestimate that timing chain it is really critical it is had for you to replace it cuz you could miss the timing settings go to shop
This is beyond the casual do it yourself job. If the timing chain has failed, this is extremely rare as it is a double chain, there will be associated problems with timing and potential damage to the valve gear and piston crowns if it failed whilst the engine was running. This all adds up to an engine strip down and rebuild. Given the time and cost of parts it maybe cheaper to source a good second hand or reconditioned engine unit or perhaps even getting a replacement well loved Merc. Which ever route taken it sounds like a trip to local garage for an appraisal and price estimate would be the best first step. Fingers crossed it could be simple job of adjustment of the existing chain if still intact. If the old chain is intact but cannot be adjusted due to excessive wear it is possible to 'pull' a new chain through the engine using the old chain. Again the guys at Mercedes stealerships are pretty good at this sort of thing although pricey.
50K miles IS premature for a chain to break. They're pretty tough. Are you sure it's a chain? If it is a BELT, it could be old and broke due to age. They are a synthetic rubber and eventually they deteriorate over time.
You don't specifically state what kind of car your friend has, so I am presuming a 1998 Accord. That car should have a belt.
Either a belt or a chain can fail prematurely if the tensioning system fails. This will allow excessive slack in the chain or belt which will cause damage to the affected drive components. The tensioning systems can fail due to one or more of the following:
Lack of oil pressure, failed tensioning springs, failed pulley bearings, over-revving the engine for ridiculous periods of time, and failed plastic guide components.
Belts can also fail due to chemical contamination (oil or antifreeze leaking on the belt).
Finally - the water pump can fail which will derail the belt as the belt drives the water pump on many Honda 4 cylinder engines.
your intrepid doesnt have a timing belt it has a chain. there are major problems with these engines, theres a big one with the chain jumping due to a tensioner breaking or a guide,heres a diagram for the chain setup.this is a very important setup make sure you use correct sprokets in the right place and also if it jumped timing il bet you may have some bent valves,
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.
Hi there,
you will need new upper timing chain and sprockets. Common problem on altima your year. Nissan has TSB for it. First they had us remove the upper timing chain guide, but after that, they had us replace all top chain components.
