How often should timing chain be replaced on Mercedes 190?
The early M102 engines were originally fitted with single row timing chains, and there have been cases of premature failures. In my opinion, any M102 engine with a single row timing chain should have the chain and tensioner replaced every 100k miles or earlier if the chain becomes noisy.
When do you know to change the timing chain?
A timing chain runs inside the engine, as it needs to be lubricated by the engine oil. A timing belt typically needs to be replaced between 40,000 and 100,000 miles depending on the vehicle and it’s a few hundred dollar repair. A timing chain doesn’t need to be replaced unless there is a problem with it.
When did Mercedes Benz add double row timing chain?
Mercedes-Benz updated the M102 engine to receive a double row timing chain in 1988. These chains are a lot tougher, and under normal conditions, should last the “lifetime” of the engine. “Lifetime” can be very roughly defined as 200k miles.
How long does a Mercedes-Benz 190 duplex chain last?
These chains are a lot tougher, and under normal conditions, should last the “lifetime” of the engine. “Lifetime” can be very roughly defined as 200k miles. The above also applies to the 2.3-16 Cosworth engine. The 2.3-16 engine had a single row timing chain just like the standard M102. Only the newer 2.5-16 already had the updated duplex chain.

Can a bad timing chain cause an engine to fail?
3. Engine won’t start or fails. A broken timing chain will cause an engine to not start or fail while driving. If the belt is already broken, the engine won’t have enough compression to start. If it breaks or jumps while driving, the pistons will be damaged from contact with the valves.
What are the bright links on a timing chain?
Locate marks or “bright” links in your timing chain. These links are brighter than the other links and are used to align your engine. Set your engine to top dead center. To get your engine to top dead center, line the bright links on the timing chain up with the marks on your camshaft and crankshaft gears.
Is the timing chain on an engine made of metal?
In order for your engine to fire, the timing chain must smoothly rotate around the gears without hesitation. Although the timing chain is made out of metal, it is subject to wear and tear and may break if not replaced as recommended by the manufacturer.
