Why would I have my engine rebuilt?
The usual reasons for rebuilding an engine are loss of compression, excessive oil consumption, or excessive oil clearances.
The symptoms of loss of compression are extended cranking (hard to start), lack of power, or a misfire (running rough). All of these symptoms can be caused by lack of compression, but they can also be caused by other things, so before the engine is rebuilt it should be diagnosed by performing a compression or leakdown test.
Oil consumption is the loss of motor oil even though there are no significant external oil leaks. It can be caused by worn valve guides, dried valve guide seals, stuck oil control rings, or excessive cylinder to piston clearance. It also can be caused by a very inexpensive PCV valve. So try replacing this first before condemning the engine.
The most common symptom of excessive oil clearances is an awful knock coming from the engine. Low oil pressure is also a symptom of excessive oil clearances but is less common (by the time the oil pressure goes low there’s usually an engine knock evident). Engine knock can be caused by worn rod bearings, main bearings, piston pins, pistons, and cam bearings. Sometimes some types of engine knock can be repaired with the engine in the car. The engine must be partially disassembled to know for sure.
Is it worth it to rebuild or repair my engine?
Most of the time it comes down to a personal choice. There is no good formulaic solution to the question. There are cases where it’s an easy decision. If the car is 20 years old with 300,000 miles on it and is falling apart at the seams then it’s pretty obvious it makes no sense to fix it. If the car is 5 years old and in good shape it’s definitely worth fixing. Most of the cars that need engines fall somewhere in-between. Our best advise is to have a full vehicle inspection done before having the engine repaired, then consider the total projected cost of the engine plus any needed maintenance and repairs. Consider whether you like your car or not and the cost of buying a new or used car you would like. Keep in mind that there is some uncertainty in buying a used car even if you have it inspected. Remember to include financing costs and full coverage insurance when thinking about a new car. In some cases it is worth doing repairs to a car in excess of its bluebook value.
So my car will be like new, right?
Nope. The car is much more than just the engine. There’s steering, suspension, transmission, brakes, tires, axles, fuel injection, smog equipment, and a lot more. A car with a rebuilt engine will still run poorly with bad ignition wire, and still fail smog with a bad O2 sensor, and still overheat with a bad radiator.
How do I break in the rebuilt engine?
Vary the engine speed and load. Don’t use over 75% throttle. Don’t go over 75% of the maximum RPM. Don’t use synthetic oil. Don’t let the engine idle for extended periods. Don’t cruise on the freeway at the same speed for extended periods. It should only take about 500 miles to break an engine in. After that change the oil and do what you want. Believe it or not, how you break your engine in can make a huge difference in how long your rebuilt engine lasts and how much oil it uses. You should also be aware that the rebuilt engine will burn more oil as it is breaking in, so check the oil frequently.
Why did the engine go bad in the first place?
This is important to consider. If the engine overheated due to a partially clogged radiator and a new engine is installed without addressing this, the new engine will surely fail too. If your maintenance was spotty and you don’t change your habits, then the new engine will fail as well. There usually is a correctable reason for engine failure. Most of the engines we work on will last the life of the car without needing a rebuild. We have one customer with almost 400,000 miles on her original engine. There are of course fluky failures like an Integra that burned a hole in the head behind the back side of the valve seat at 40,000 miles and an Civic that dropped a valve for no apparent reason, but problems like these are rare. So if the cause of the engine failure in not apparent to you, be sure to ask.
