Is a broken timing chain fixable?
However, if the timing chain breaks, the piston and valve will collide. The result will be a damaged cylinder head, valve, piston, cylinder, and/or camshaft. These are very expensive items to repair or replace. You’d probably be better off either purchasing a new engine or trading in your car for a new one.
What makes you think you need to replace the timing chain out?
It is a common problem with these engines. The chain guides fall apart so the timing chain jumps time. I don’t see where this is an interference engine to have caused damage. What makes you think you need to replace the engine?
What are the symptoms of a bad timing chain?
Symptoms of a failing timing chain include: 1 Timing chain noise 2 Engine misfire and poor performance 3 Difficulty in starting the vehicle 4 Illuminated check engine light 5 Engine vibration or shaking when idling 6 Engine won’t start
Can a broken timing belt cause engine damage?
In a non-interference engine, no matter how low the valves go, the piston will not make contact. Internal engine damage is unlikely. A good mechanic can diagnose if the engine can be repaired, or if a new engine or used engine is needed. Or if the car should be scrapped.
Where is the timing chain on a BMW?
The timing chain is located in the rear end of the engine, an area that was not designed to be serviceable. Thus to fix the broken timing chain, more often than not, we would have to remove the entire engine.
Common signs of a faulty timing chain include engine misfires, metal shavings found in the oil, and rattling sounds from the engine while idling. Since the inception of the internal combustion engine, one constant has remained – all of them have a timing chain or timing belt.
Which model has the timing chain problem?
If you own a BMW model from any of the BMW 1, 3 or 5 series manufactured between 2007 and 2011 then your car is liable to have a timing chain problem. The luxury German machines are prone to a specific engine problem, a timing-chain-wear caused largely to the use of the newer N47 motor engine.
What does a loose timing chain sound like?
Listen for a metallic sound that resembles a rattling or scrapping noise. The sound can be intermittent or constant, but it will be a metal to metal contact. Such a noise will reveal a loose timing chain hitting the inside of the timing chain cover every time it rotates.
What is a timing chain kit?
A timing chain kit is a selection of parts that link the movement between the engine crankshaft and camshaft. A basic timing chain kit will include the timing chains (metal links), camshaft and crankshaft sprockets, tensioners, guide rails, and necessary gaskets and seals.
