Engine Frequently Asked Questions

Engine Frequently Asked Questions

Is it worthwhile to have an Engine Remanufactured?

That's a good question. If the body of the vehicle is in good shape it is normally worth remanufacturing the engine. This also gives you an engine that can go another 100,000 miles or more if treated properly. Consider how much it would cost to replace the vehicle. Would you be replacing it with a used vehicle that also may be in need of engine repair in the near future? What would you do with your used vehicle that has a bad engine (scrap it)? We think if you would like to get 2 or more years out of your vehicle then it is worth remanufacturing.

How to break-in a remanufactured engine?

Breaking in a remanufactured engine is a painless task. Basically just avoid lugging and prolonged same speed driving for the first 500 miles. This just means avoid any long trips during the break-in. The first oil change should be made at or close to the first 500 miles and after that every 3 months or 3000 miles. Check your oil at least every time you get gas during the first 3000 miles as your newly remanufactured engine may use some oil. This is due to the rings breaking in and is completely normal. Watch for any leaks or engine lights. If you notice either please bring your vehicle in immediately, remember it is better to be safe than sorry. It is quite common for an engine to use a little oil during the break-in period so check your oil frequently. You should also change your anti-freeze every 2 years or 24k miles.

Do I need a remanufactured engine?

If your car or truck is burning oil, smoking, making odd noises, leaking fluids, overheating, or showing other tell-tale symptoms, you should get it checked. Chances are you may have a serious engine problem. We have the qualified personnel and technology necessary to evaluate your engine's condition. In fact many customers who come to us learn that, despite a previous diagnosis, they don't need a new engine, only certain repairs or adjustments. But if after testing, it is determined that you need a engine, we can take care of you at our facility.

Why don't I just buy a new car?

A new car today averages $15,000 - $25,000 not even counting the added costs of putting it on the road - registration, sales and excise taxes, increased insurance premiums, and car loan interest - which will add thousands more to your total cost. In addition, depreciation will cut your new vehicle's value in half within three short years. It's no wonder that the percentage of older vehicles on the road is growing, according to national surveys, and that large companies like UPS and Federal Express retain their vehicles longer through engine replacement programs.

Why don't I just buy a used car?

A used car is often an unknown. Is it really any better than your old one? Do you know its inside story? Can you get a good warranty? There are good used cars out there, but remember you can buy a bigger problem than the one you have if you're not careful. Unless your current vehicle's body or chassis is really beyond repair, you should consider replacing the engine.

Why don't I just buy a used replacement engine?

A used engine usually costs considerably less than the price of a remanufactured engine, although the installation cost is the same and the warranties typically run from 30 to 90 days only, and don't cover labor. Most important, the engine is just what you could get with a used vehicle power unit, uncertain quality and life expectancy.

What's wrong with buying a rebuilt engine?

A rebuilt engine is a step in the right direction, but it is most often only a halfway solution. A rebuilt engine may have had damaged or worn parts changed, but other essential components may remain in "not new" condition. Even rebuilt engines with new bearings, rings, valves, and seals retain many older components, leading to shorter life expectancies for rebuilt engines.

What is so great about remanufactured engines?

A remanufactured engine is assembled essentially the same way engines are for a new car. The major reusable components are machined, bored, welded , planed, and polished to the highest possible tolerances. Crankshaft, block, and head castings are subjected to precise checks to guarantee their integrity and fit. The remanufactured components are then assembled together with entirely new, factory fresh pistons, rings, bearings, timing components, gaskets, seals, bushings, lifters, oil pump, and more. The engine is then thoroughly tested before it is given to the customer.

What is the startup procedure for a remanufactured engine?

The initial start-up of any remanufactured engine is critical. Performed correctly it will insure a long engine life. However, make a mistake here and it can result in immediate engine failure. Follow the steps below.
  • Cooling System
    Start by completely filling the cooling system. In most cases this is made easier by removing the thermostat. Be careful on vehicles where the engine sits higher than the radiator, because pockets of air can become trapped creating hot spots that can cause engine damage. Make sure you get all the air out of the cooling system and engine before you start the vehicle. For more specific instructions refer to your repair manual.

  • Ignition System
    Double check your ignition wiring and firing order. If possible static time the engine, this will help it start easier.

  • Fuel System
    Double check all fuel connectors. Be extra careful on fuel injected cars that have much higher fuel pressure. Double check all vacuum routing connections. When in doubt refer to your repair manual or the vacuum routing sticker in the vehicle's engine compartment.

  • Lubrication System
    The engine should be properly prelubed before it is started. This means supplying pressurized oil to all the bearing and wear surfaces in the engine before it is started. On engines where the ignition distributor drives the oil pump, this can be done by removing the distributor and turning the oil pump with a drill motor until oil appears at the rocker arms. A mechanical oil pressure gauge should be installed so you can monitor oil pressure during start-up.

  • Start-Up
    Verify you have oil pressure (at least 20 psi) and immediately raise the engine speed to 2,000 rpm. Fluctuate the rpm between 1,800 and 2,200 for the first 15-20 minutes. If the engine fails to start quickly check your fuel and ignition systems again. Do not crank the engine excessively as this can cause damage to the bearings and camshaft. During this 20 minute period adjust the ignition and fuel systems to the manufacturers specifications.

  • After Initial Start-Up
    Let the engine cool down (at least 3 hours) and then re-torque the intake & exhaust manifolds to the manufacturers specifications. Check the tension of the rubber belts that drive the accessories, they will stretch after the initial start-up and can become loose. A loose water pump belt can cause the engine to overheat. Change the engine oil. If your engine has a flat tappet camshaft be sure to use the appropriate oil or use an additive that is specifically for flat tappet camshafts.

  • We Can Do The Installation For You
    There is a lot of work involved in installing an engine properly. We can provide this service to  ensure your remanufactured engine has a long life.

What do I do if the "Check Engine" light comes on?

You're driving along in your vehicle and suddenly a yellow light illuminates on your dash telling you to check or service your engine. If you're like most car owners, you have little idea about what that light is trying to tell you or exactly how you should react.

This is the most misunderstood indicator on your dashboard, the "check engine" light can mean many different things, from a loose gas cap to a seriously misfiring engine.

It doesn't mean you have to pull the car over to the side of the road and call a tow truck. It does mean you should get the car checked out as soon as possible.

Ignore the warning, and you could end up damaging expensive components. It also can be a sign that your car is getting poor fuel economy and emitting higher levels of pollutants.
