It is possible but highly unlikely. If it were leaking oil from a blown head gasket you would have lots of other symptoms such as overheating, coolant mixed with the oil, white smoke from the exhaust, and loss of coolant with no apparent leak.
Worn main or rod bearings if pressure drops at idle. Faulty gauge or sending unit. Faulty oil pump or clogged pick up screen. Piece of crap car. Etc.
If your engine has a faulty intake valve and it drops, shut the engine off as soon as you can. The loose part will eventually destroy the engine, sometimes to the point it cannot even be rebuilt but will need a replacement.
You may have blown a head gasket, check you oil to see if the antifreeze is leaking into there.
No
If a dog drinks eye drops, the effects will vary based on the type of drops. Visine will cause severe diarrhea in even small doses, while saline drops are harmless.
The cause is the condensation of water vapors.
When it was damaged. If you don't have coolant leakage, but the level collant drops down it means you have internal leakage of coolant. You must replace the head gasket of course if want to drive your car. van over heats
The water level drops, and you have to add to it every so often. If not, it will get hot, often, and easily.
My experience was that the "spider gasket" inside the multi-port valve was unseated and allowing blow-by. Replace the gasket.
No, in and of itself, using Ciprofloxacin eye drops in your ears one time should not cause hearing loss.
Yes it does, I keep bottled water and cans of soda in mine in my unheated garage when the temp drops below freezing in the garage and it works for me. I am sure that if it was for a long cold spell it would eventually freeze.
You have a blown head gasket i would not drive it until it has been fixed
