Answer:-
The 1ZZ-FE engine, found in many Toyota models, is known for its reliability, but it does have a few common issues. Owners often report oil consumption problems, which can be due to piston ring wear. Some also experience issues with the timing chain tensioner, leading to noise or potential engine damage if not addressed. Additionally, the engine can suffer from oil sludge buildup if maintenance is neglected. Regular oil changes and using high-quality oil can help mitigate these issues. Despite these problems, with proper care, the 1ZZ-FE can still be a long-lasting and dependable engine.
