...technically, no you won't need to replace the motor. What will happen is that all the moving parts that depend on fresh oil for lubrication will suffer from its absence, with increased wear (same if there is oil but it's overdue for replacement due to thermal breakdown or contamination). But technically assuming that it won't turn over, a motor rebuild would probably be in order. Not certainly because it might not turn over for other reasons.
It's a lot cheaper to get a working motor and have it put in your car, though, because a motor can have hundreds of thousands of miles on it and still run. A rebuild can easily cost $2k or more to have it done by a competent mechanic.
Have someone drain out the oil and replace the filter, now! Do not run the engine! This is not good for the engine!
yes.
if the miles on the engine aren't too high, then just replace the head gaskets. if the whole engine is tired go ahead and swap out the motor. its a lot cheaper to do the gaskets then to buy a new motor.
Put a jack under the engine for stability. Unbolt one motor mount, and jack the engine up slightly. The mount should be able to be removed, replace it and repeat for the other side.
check the head gaskets before you replace motor
No. Get rid of the car or replace the engine!
Take it to the shop
Remove the engine .....bugger of a job
Worn rubber on motor mounts. Replace mounts.
Engine, not motor, and, while not impossible, such a swap would cause a lot of problems, not the least of which would be the car engine not being protected against saltwater corrosion.
It is an interference engine, replace the belt every 60,000 miles.
Each motor mount is held in place by a retaining bolt. The retaining bolt goes through the middle of the motor mount. Remove the retaining bolt. Jack the engine up. Replace the motor mount.
