If there is no compression after changing the timing chain on a 230 SLK, it could indicate that the timing chain was not installed correctly, leading to misalignment of the camshaft and crankshaft. This misalignment prevents the engine's valves from opening and closing at the proper times, resulting in a loss of compression. Additionally, if the timing chain was replaced without addressing worn components or if any debris was left in the combustion chamber, this could also contribute to the issue. It's crucial to double-check the timing marks and ensure proper installation during the repair.
Usually that is a sign of a broken timing belt or timing chain.
Timing chain slipped or broke
The year and engine size would help but you may have a bent valve or bent pushrod for # 4 cylinder if that is the only cylinder that has 0 for compression.
Never, it will last the life of the engine.
The chain will last the life if the engine and does not require changing.
You may have compression on any cylinder where the valves happen to be closed, but you will not have compression on all cylinders. 1991 Sable does not have a 305 engine.
If a timing chain broke, the engine wouldn't run and a compression test would read "0".
The engine would not run. The engine would lack compression.
Highly doubtful, the engine has a timing chain and the ignition relies on a crank sensor for timing. But if the chain did jump you could probably tell by doing a compression test.
Yes, a slippage in the timing chain can prevent a 2007 Honda Fit from starting. The timing chain keeps the engine's camshaft and crankshaft in sync, allowing the engine's valves to open and close at the correct times. If the chain slips, it can lead to incorrect timing, resulting in a loss of compression or valve damage, which can prevent the engine from starting. Therefore, addressing timing chain issues is crucial for the engine's proper function.
Broken cam or timing chain is the most likely cause.
Factory recommendation is 90,000 miles. If it is a timing CHAIN and not a belt, it doesn't require changing. It should last the life of the engine.
