Warranty Information:
This engine comes with a 90 day warranty that begins on the day the engine is received by the buyer. The warranty covers the engine block, crankshaft, pistons, rods, bearings, oil pump, cylinder head, head gasket, camshafts, valves and lifters against any defects that prevent the engine from operating as intended from the factory or make noises consistent with damaged engine internals ( rod knock, spun bearings, etc). Every engine we list has been fully run tested, compression tested and when possible test driven to make sure it runs smoothly, makes no odd noises and does not overheat.
What is not included in the warranty is common wear and tear items such as: timing belt, water pump, thermostat, spark plugs, spark plug wires, sensors and seals. While these items were in working condition at the time of testing, their lifespan is usually shorter than the internals of the engine and are therefore not covered under warranty. If any seals or gaskets are leaking at the time the engine is being tested and removed, or any sensors broken or defective, they will be noted in the item description. No labor, diagnostic or towing costs will be covered under warranty. In the event of a warranty claim, please be prepared to supply pictures, video and/or a statement from a shop/mechanic to validate the claim. For diagnostic purposes during the process of a warranty claim, the engine must remain in the car as installed. Beginning the removal process or any disassembly of the engine prior to our approval will void the warranty. This warranty is non-transferrable. It is only applicable to the original purchaser.
Situations that will void the warranty:
Overheating of the engine. We install ‘heat indicator tabs’ on every engine prior to shipping that show when an engine has been operated at a temperature significantly higher than normal operating temperature. If these tabs show signs of overheating, the warranty will be void. If the engine in your car is being replaced due to damage from an overheating condition please locate and fix the source of the issue prior to running your new engine.
Not running fresh oil and oil filter in the engine (these engines ship drained of all fluids).
Installation of an aftermarket turbocharger/supercharger, Nitrous Oxide kit, or aftermarket tune.
Installation errors that are found to have caused the engine to run improperly.
Operation outside of normal intended road usage, such as track days, racing, drifting, etc
Disassembly of the engine besides basic preventative maintenance such as oil seals, spark plugs, cooling system, and timing belts. Removing the cylinder head, head gasket changes, replacing or modifying internal rotating components such as bearings/camshafts/crankshafts, and other major work done to engine would void warranty.
