How to Remedy Insufficient Cylinder Pressure?
2 Answers
Check the car's valves. If the insufficient pressure is caused by poor valve sealing, the valves should be ground or replaced. You can check whether the car's cylinder block and cylinder head are leaking. If the insufficient pressure is caused by leaks in the cylinder block and cylinder head. Check for leaks between the piston rings and the cylinder walls. If the leak is between the piston rings and the cylinder walls, the piston rings and cylinder liners should be replaced promptly.
I've been driving for over 20 years and have encountered insufficient cylinder pressure several times. It's often caused by worn piston rings, poor valve sealing, or cylinder wall damage, leading to weak engine acceleration, increased fuel consumption, and even black smoke. For remediation, I recommend first performing a compression test to identify the leakage point, such as determining which cylinder is problematic. Then, carry out targeted repairs—replace the piston rings if they're damaged, grind the valve seats for valve leakage, and consider cylinder boring or block replacement for severe cylinder damage. The entire process should be done at a professional repair shop, as they have the tools for precise detection. Don't forget, regular maintenance is crucial; changing the oil and checking spark plugs periodically can prevent pressure loss. Ignoring it can significantly shorten engine life, so address it promptly upon discovery to ensure driving safety.
