Do rebuilt engines last long?

Why does my engine oil keep running out?
A car may be burning oil for a few different reasons. The two most common are because it is bypassing the piston rings, or leaking past the valve seals. … If your engine’s piston rings are worn out from high mileage or poor maintenance they can allow small amounts of oil past to be burnt during the combustion process.
How do I know if I have bad valve seals or piston rings?
It simple to test. If you accelerate and blue smoke continues until RPM is high all the time these are rings. If you see smoke just few seconds after acceleration these are valve seals. The more idling time the more blue cloud with acceleration also indicates the valve seals are bad.
When should you replace piston rings?
Piston replacement intervals are typically outlined in your machine’s factory service manual. Using dirt bikes as an example, many manufacturers outline a piston and ring replacement schedule of every six races or 15-30 hours for a four-stroke, depending on the machine.
Why is my car losing oil but no leak?
If the engine isn’t leaking oil, and the PCV system is working as it should, that means your engine is probably wearing out inside. … That oil will burn up in the engine and could lead to damage.
