Customer Feedback

"A few months back we were in need of a new race car motor, and we asked a few racers and they all said go to dennis at DVC machine and we did so. Dennis built us a amazing motor in a short amount of time. We informed dennis that we would need the motor alot sooner than expected and he worked his butt off to get it ready for us when we needed it! We have had ZERO problems running this motor at very high RPMS! DVC is HIGHLY recommended! Thank you Dennis and everyone at DVC!"

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.

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.
