The time it takes to break in an engine differs by manufacturer. Most recommend avoiding high RPMs in the first 1,000 to 1,500 miles; a maximum of 3,500 RPM is the ballpark for diesel engines, rising to 4,500 RPM for petrol.

Run a couple hard throttle accelerations up to about 5,000 rpm and once again coast back down to 20 miles-per-hour. Let the engine cool, change the oil and filter, and check the coolant level. Drive the next 500 miles normally, keeping the engine below 5,000 rpm and minimizing operation at idle.

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.

3 Signs you may need an Engine Rebuild

• Banging or Knocking Sound. An engine’s moving parts rest on engine bearings.
• White Exhaust. If oil burns with gasoline it will cause your exhaust smoke to be a very white color.
• Metal Flakes in Engine Oil.

Engines- in theory they can be overhauled indefinitely. In fact, overhauls are only a recommendation for non commercial ops. Real world- after 2-3 overhauls may as well exchange for a 0 time already overhauled or rebuilt engine.

Check your engine for fuel, coolant and oil leaks, and make sure you’re getting power to all of the right places. For computer-controlled engines, make sure that you have the right ECU, tuned correctly for your first fire. Older engines that feature distributor-driven oil pumps sport a handy detail: easy priming.

A scheduled overhaul is almost always less expensive than a new engine. Rebuilding to repair is usually cheaper than buying a new engine, too. You may save up to half of the cost of a new engine by rebuilding. However, sometimes rebuilding is not a good option.

It has been declared that rebuilt engines are better than the engines originally installed at the factory, dependable, reliable and backed by warranties. Your most reliable and cost-effective choice for engine repair is to choose to replace your current engine with a rebuilt engine.

A timing light needs to be hooked (in most cases) to number 1 spark plug wire before engine start-up, total timing checked, so you don’t do damage to your new engine. Your engine needs to be primed with oil before engine start-up.

As soon as your water temperature just starts to rise, bring rpm up to 1800 rpm, and check ignition timing to make sure you are approx. 22-25 degrees timing for engine break-in. Run the engine at 1800 rpm for at least half an hour, making sure someone is monitoring oil pressure and water temperature at all times!

Older engines that feature distributor-driven oil pumps sport a handy detail: easy priming. A tool available at nearly any auto parts store can attach to the chuck of a drill and spin the oil pump, priming it.

Your engine needs to be primed with oil before engine start-up. Have someone sitting in drivers seat at all times on engine start-up, monitoring water temperature, oil pressure, and rpm. It is critical that the engine never idles for the first half hour!
