Intake manifold

not really, intakes do not normally fail but if they did more than likely your car would quit running. if you have no oil pressure then check your oil level first. then have things like pump checked or if driven by a chain maybe chain has broken. Bearing could have failed as well but normally you'll hear a knock if that happens.

Thanks, also if intake did fail could water have leaked into the oil?

This is a follow up question from here https://www.2carpros.com/questions/water-in-oil-loss-of-pressure

Could be-check the oil if its milky

What actually happened to the manifold what was the failure?

Could you please tell me how thermo switches disconnect?
