| 1.) |
ANY engine damage caused by driving vehicle with
engine light on or disconnected |
| 2.) |
BURNED OUT BEARINGS caused by lack of lubrication.
This type of failure can be easily identified by the pulled and scored surfaces that did
not completely burn out, or if the bearings are all burned out. |
| 3.) |
THRUST FACE BEARING WEAR, this is not the fault of the
rebuilder. It is caused by improper adjustment of the clutch or riding the clutch. There
are also several automatic transmission problems that cause this, including cooler and
line problems. |
| 4.) |
BROKEN ROD DAMAGE due to driving a vehicle after rod
bearing failure and subsequent resulting damage. |
| 5.) |
SCORED CYLINDERS AND PISTONS caused by overheating.
This type of failure can usually be identified by the fact that usually more than one
piston is damaged and by the discoloration of the piston and cylinder walls. In some cases
the engines have run so hot that the cam bearings have melted. |
| 6.) |
MELTED PISTONS, BROKEN RING LANDS, HOLES BURNED IN
PISTONS caused by detonation and pre-ignition. |
| 7.) |
RINGS WORN OUT PREMATURELY due to faulty carburetor,
fuel injection or plugged air cleaner, causing excessive amounts of gasoline to be induced
into the combustion chamber that washes the oil from the rings and cylinder walls. A
defective or no air cleaner that allows dirt and dust to enter the combustion chamber can
also cause premature ring and/or cylinder wall wear. This type of failure can be
identified by the excessive wear on the cylinder walls as well as the rings. |
| 8.) |
BROKEN PISTONS caused by bolts, lock washers, or
pieces of broken rings, from the previous engine, that have been left in the intake
manifold or cylinder heads. These pieces of foreign material are sucked into the
combustion chambers when the engine is started, and can severely damage the piston and
cylinder wall. |
| 9.) |
BROKEN PISTONS & BENT OR BROKEN RODS caused by
hydraulic lock. This type of failure can be identified by bent rods with no physical mark
on the rod. The rod will have the appearance of having buckled under pressure rather than
just plain bending. Since liquid does not compress when the engine is started, the force
of the crankshaft with the inertia of the flywheel and starter, will create enough power
to bend the rod. The liquid could come from the coolant leaking into the combustion
chamber, flooding, or a defective or leaking carburetor or fuel injectors that allows
gasoline to drain into the intake manifold and be sucked into a cylinder when the engine
is first started. |
| 10.) |
HEAD DAMAGE OR GASKET FAILURE due to overheating or
detonation. Overheating is mainly due to a plugged or faulty radiator, broken radiator
hoses, heater hoses, leaking or worn out water pump, faulty thermostat, or defective fan
clutch and fan belt. Head gaskets, exhaust gaskets, intake gaskets and seals installed
correctly are not covered under the warranty. |
| 11.) |
BURNED VALVES AND SEATS caused by improper adjustment.
Valve adjustment is an owner maintenance responsibility and it must be done according to
the manufacturers specifications and mileage requirements. |
| 12.) |
VALVE & SEAT FAILURE due to unleaded fuel use.
This has an appearance of the valve being pulled down in the seat. This is due to some
engines cannot run on unleaded fuel as they were never designed for this. We recommend our
unleaded package. |
| 13.) |
WARRANTY IS VOID if any faulty repairs or adjustments
are made (other than by our mechanics), abuse, neglect by operator or by person
servicing vehicle, driving vehicle after defect is apparent, low oil pressure, overheating
noise or failure to clean parts thoroughly that are not installed by us. |
| 14.) |
PREVIOUSLY REPAIRED PARTS such as valve seats, crack
repair and broken or cracked cranks, pins & welding. Back || Next Page
