Chain jumping is the most serious problem with this reliable engine, usually due to the stretching or wear of the hydraulic tensioner. Valves are often bent in this case. The official lifespan of the chain is 250,000 km, but it usually lasts half as long. Valve burning is also a common issue. Hydro compensators are not provided in this engine, and valve clearance adjustment is done by selecting pushers, which is expensive as it requires removing the camshafts. Owners often delay this procedure, waiting for their valves to burn out. Inexpensive Chevrolet models have lower quality accessory equipment, and starter failures, buzzing generator bearings, and pump leaks are regular occurrences. Other drawbacks mentioned on specialized forums include lubricant leaks and ignition system malfunctions. It is also important to keep an eye on radiators as leaks are not uncommon and overheating can occur.
