What Causes the Ticking Sound in a Car Engine?
1 Answers
Car engine ticking sound is caused by hydraulic lifter issues and excessive valve clearance in the engine cylinder head. This occurs because both the engine valves and hydraulic lifters experience certain wear over time. During cold starts, the oil pump hasn't fully built up oil pressure yet, leading to insufficient lubrication of components. Regular maintenance is essential for car engines: 1. Regularly change engine oil and oil filter: When oil passes through the fine pores of the filter, it traps solid particles and sludge. 2. Maintain good crankcase ventilation by servicing the PCV system regularly: Remove contaminants around the PCV valve as airborne pollutants can accumulate and potentially clog the valve. 3. Periodically clean the crankcase: Use BG105 cleaner regularly to maintain internal engine cleanliness.
