Rebuilding an engine will also extend the life of your vehicle, allowing you to drive it for several more years if the chassis and other essential components are sound. The work typically comes with a warranty covering at least one year or 12,000 miles. Other warranties might extend for three years and unlimited miles.
Remember how the starting, stopping, and idling, with the idling add up with the engine mileage. With those factors considered, an engine overhaul may be needed at around 750,000 miles. Once the engine overhaul is completed, you can expect to get another 10,000 engine miles of driving and/or idling time.
Frequently, rebuilt engines are superior to even new car engines because better parts are used, or design changes in parts correct problems with the original engine. Rebuilt engines are dependable, reliable and are backed by the engine manufacturers warranty program.
Probably the biggest disadvantage is cost. Engine rebuilding is a VERY expensive process. It is generally not cost effective compared to other options, such as used engines or even replacement of the vehicle.
How long do I keep an engine running after a rebuild? As a general rule, new or rebuilt engines should be run in for the first 500-1000 miles. The first oil change should occur after the first 300 miles or so.
You can make your engine last longer by having a detailed plan for how you will care for it and reduce the risk of early engine trouble. Your engine care plan should include regular tune-up visits, oil changes, warming your engine and cooling it down properly and lightening the load as much as possible.
It`s normal for your car`s gasoline engine to run for around 200,000 miles before it needs a serious overhaul, or you need a new vehicle. But diesel engines can continuously run for an impressive 1,000,000-1,500,000 miles before needing any major work.
All in all, modern car engines are more efficient, smaller, relatively more powerful, smarter, and less prone to wear and tear. On the other hand, repairs and servicing now require more skill and consume more time.
A major overhaul consists of the complete disassembly of an engine. The overhaul facility inspects the engine, repairs it as necessary, reassembles, tests, and approves it for return to service within the fits and limits specified by the manufacturer`s overhaul data.
An engine overhaul can bring your engine back to life. Essentially, it is the process of deconstructing the current engine and having new internal pieces placed. This involves new cylinders, valves, springs, and more. If you think you are having engine problems, don`t wait to bring your car in.
Often, engines which approach mileage of 300,000km or those that have been poorly maintained will need more than an engine overhaul. They will require a complete engine re-build.
When a car`s engine begins to sound `funny`, when it idles, while it is accelerating, or as it turns off, then you may need an engine overhaul. Even smoke billowing from the exhaust pipe, or if your car runs too hot, it could spell serious engine damage.
Traditionally performed between 500,000 and 1,000,000 miles, engine rebuilds can improve mileage and extend the engine`s life. Smaller trucks may not need to be rebuilt if properly maintained.
If you rebuild the engine in your car are you essentially starting from zero miles again? If the engine was built buy professional and installed correctly yes the engine and engine only is starting from zero miles again providing you take all the measures to break it in and change oil when needed.
The biggest advantage of buying an OEM rebuild kit is that it contains the same parts your engine was built with, so you know they`re all good quality parts. You can buy parts for a repair and know that they will fit correctly. This gives you peace of mind, since rebuilds can easily get expensive.

the most relevant questions and answers related to your specific issue

vehicle using oil after complete engine overhaul
ANSWER : Engines that have been completely overhauled and rebuilt will burn some oil for the first couple of thousand miles. It is in these first couple of thousand miles that the engine does a lot of breaking in. After an engine overhaul, it is a good idea to change the oil after 500 miles and again after 1000 miles. Doing this will keep the engine clean of any contaminants associated with engine break in.

New vehicle engines go through a break in stage before the engines are ever installed in to a vehicle. When having your engine rebuilt, it is the re-builders responsibility to inform you of proper engine break in for your vehicle. Once an engine breaks in, oil consumption typically slows down dramatically. If you continue to go through oil, I would follow up with your engine builder to determine the cause of your vehicles excessive oil usage.

However, if you want a second opinion on this, contact a certified mechanic who can diagnose your oil issue firsthand.

Interested in purchasing a diesel 6.0 engine.. engine has been taken out vehicle how can I check if this is a good engine
ANSWER : About the only safe way to see if and how it runs, would be on an engine run stand.or engine dynomometer. Something an engine rebuilder may have. They would set the engine up on the stand, connect power, fuel, cooling, and run the engine. Try an internet search for any local shops that have a dyno or run stand and ask how much they would charge. Find out how the engine was stored. It should be treated the same as if it were still in the vehicle and the vehicle stored for a long time. Oil should be changed. A little light oil squirted into the cylinders through the spark plug holes, cranked with fuel and ignition disabled to allow oil to circulate before starting. Things like that. If you are going through a private seller, you may not have any recourse if something happens once you buy and install it. Going thorough a salvage yard may get you at least a short warranty and they may even cover a portion of the labor involved to swap the engine again should it have issues.

The engine is making rattling very high noise when you start the engine and constant.
ANSWER : The fact that the oil pressure drops when slowing down or stopping would suggest that the oil pressure is lower at lower engine RPM’s. This means that the oil level volume is low. The oil capacity in an engine is designed to correlate with oil pressure at any given RPM. When it is full, there should always be constant oil pressure assuming there is no oil leaks. I would suggest having an expert from YourMechanic come to your home to diagnose your vehicle and make appropriate repairs to your vehicle.

Can front wheel drive car engine power rear wheel drive
ANSWER : Anything is possible with enough engineering. The changes you are looking at would take major structural changes and would definitely not be an easy job. You could possibly consult a manufacturing engineer to get more details on how this could actually be carried out and whether it would be feasible.

Loss of power, weird sounds from the engine and hissing sound from throttle body, and a code P1346 1999 Lexus IS200
ANSWER : Hello – the P1346 problem code you have indicates a camshaft timing problem (variable valve timing to be specific), and is at least part of the cause of low power. The cams are out of time, relative to the crankshaft. The hissing sound from the throttle body area is likely an air leak from a hose, or some other portion of the air intake. The tapping sound could be a variety of faults, worn/leaking hydraulic valve lifter, worn cam, piston slap, etc. I recommend a timing belt service to get the cams properly timed, performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.

Engine malfunction light, reduced engine power, engine powered down
ANSWER : Hi there. There are a lot of things that can cause this on your 2012 BMW M5. I usually start by scanning the computer for codes to see what comes up. If there are not codes then I load test the alternator and the battery to see if they are failing. Low voltage in the electrical system will cause this. If that is fine, then it is usually caused by a failing throttle body. I have seen a lot of these fail due to the motors in them hanging up. If the problem is only happening intermittently, this can make the issue hard to duplicate, but you can still have tests done on the car. If you are going to have this fixed, consider YourMechanic, as a certified mechanic can come to your home or office to test the vehicle and diagnose the Engine Malfunction Light.

Check engine light refuses to go off after engine replaced
ANSWER : Hello there, you have a long series of issues going on with your 2013 Hyundai Sonata. If you keep getting a repeating oil light on than there is likely a fault in that system.

Since this fault has lasted after the engine was replaced it could be a oil pressure sensor, wiring harness fault, ECU fault, oil pump, oil strainer clogged, or low oil pressure.

To diagnose this issue properly you need a complete vehicle inspection to start from square one and identify the root cause of all this.
