Could be,
A very high mileage/worn out engine,
The PCV system not in working order,
broken rings
Excessive internal engine wear (bad rings)
Blowback into the engine sump can occur due to several factors, including excessive crankcase pressure, which may result from worn piston rings or valve seals. If the engine's positive crankcase ventilation (PCV) system is malfunctioning or clogged, it can also lead to blowback. Additionally, a malfunctioning turbocharger or supercharger can create back pressure that forces oil or air into the sump. Lastly, an overfilled oil sump can contribute to blowback by increasing pressure and allowing oil to escape through venting systems.
Yes, a bad EGR (Exhaust Gas Recirculation) valve or a faulty PCV (Positive Crankcase Ventilation) valve can contribute to engine oil blowback. A malfunctioning PCV valve can cause excessive pressure in the crankcase, which may lead to oil being pushed out of seals and gaskets. Similarly, a defective EGR valve can disrupt the engine's air-fuel mixture and combustion process, potentially leading to oil leaks or blowback. Properly functioning valves are essential for maintaining engine pressure and preventing oil from escaping.
A dead battery would not cause an engine to seize
What would cause the engine not to restart when hot Chevy Trailblazer 2007?
No, it would cause the engine to run poorly but not to seize. Lack of lubrication or overheating will cause that. Also a broken part, as in a rod, will cause it to seize.
Driving through flood water would cause the ignition to fail and stall the engine.
Many things could cause an engine to shake. One, for example, would be low coolant or oil levels.
it would cause cancer to develop
most snapped timing belts will in most cases cause engine damage,the only exception would be a freewheeling engine were valve to piston contact would be minimal an interference type engine would cause damage.
Yes it can.
