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.
What would cause the engine not to restart when hot Chevy Trailblazer 2007?
A dead battery would not cause an engine to seize
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.
Many things could cause an engine to shake. One, for example, would be low coolant or oil levels.
Driving through flood water would cause the ignition to fail and stall the engine.
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.
it would cause cancer to develop
Yes it can.
Most definitely. Any miss will cause the engine to shake. A vacuum leak will also cause this.
