When an engine starts to use oil and the car is too slow to escape its own smoke-screen, the average motorist's thoughts naturally turn to an overhaul.  The nature of the modern beast has made it much more cost-effective to install a complete remanufactured unit than to overhaul your existing engine. 

Low-mileage engines from a scrap yard may seem like a good buy, but you run some pretty big risks as far as warranty issues go. You could pay the labor charges to have it installed, find out it may not run any better than your old motor did, or worse, that it's in even poorer running condition than your old motor.  The scrap yard will probably warranty the motor and try to locate another one for you, but they probably won't pay the labor charges to take the first one back out or to put the second one in.  Not much of a deal in the end. 

We are proud to install quality Jasper remanufactured gasoline engines.  Jasper engines come with a 3-year/75,000 mile parts and labor nationwide warranty and provide a high level of confidence and reliability (full warranty disclosure available upon request).  

Jasper's thorough remanufacturing procedures assure consistent, reliable and unmatched performance. Every popular domestic complete gasoline engine is live-run tested for oil pressure, temperature, compression and vacuum pressure before it leaves the factory to ensure reliability. 

Why You Should Choose Jasper

Remanufactured Gasoline Engines:

THOROUGH CLEANING
Every engine is completely disassembled. Blocks, heads, connecting rods, crankshafts and camshafts for domestic engines are thoroughly cleaned in the Kolene Salt Bath. Molten industrial salt efficiently and thoroughly removes all contaminants that can result in premature wear to internal engine components and early engine failure. Import engines are completely cleaned through other, equally, quality oriented processes to remove contaminants.

CRANKSHAFTS
Crankshafts are precision machined to exact tolerances with no odd size bearings or journals. Thrust surfaces (domestic engines) are machined in a two step process to provide precise surface finishes for smooth engine operation and reduced thrust bearing wear. Every journal is inspected and measured with critical accuracy. After machining, oil holes are chamfered to improve lubrication and every journal polished to a smooth finish for long bearing life. Crankshafts are thoroughly cleaned with special emphasis to flushing and brushing out oil passages to remove any contaminants.

CAMSHAFTS
Camshafts are inspected for wear, dimensional accuracy and gauged for straightness. Camshaft lobes are carefully machined to correct specifications. Each shaft is Parco-Lubricated to improve lubricant adhesion, especially during break-in. Any camshaft not meeting JASPER's exact specifications is replaced.

CYLINDERS
Cylinders are bored and honed to exact specifications. Cylinder finish and size are closely monitored to industry surface finish standards as well as for accuracy and consistency through Statistical Process Control. This assures smooth piston travel and engine performance. JASPER guarantees no odd size cylinders. The block to head mating surface is closely inspected and resurfaced as required to provide the correct surface finish for today's gasket materials.

CONNECTING RODS
Connecting rods are machined and gauged to within a half a thousandth for improved operation, especially in today's engines. Rods are carefully machined to avoid taper and to the standard diameter of original equipment. All rods are checked for bend and twist to assure smooth operation.

HEADS
Heads are carefully inspected for cracks and flaws through procedures such as magnetic particle inspection and pressure testing. Every head is resurfaced to exact dimensional tolerances and the surface finish is carefully monitored for proper sealing with the block. Valve seats and guides are machined to exact specifications or replaced to assure correct valve alignment and seating and optimum engine performance.

ASSEMBLY
Every engine is precisely assembled by trained JASPER builders. Attention to such details as a final wash of new and machined parts and prelubricated camshafts, pistons, and crankshaft journals assures a clean smooth running engine that performs to your expectations.

TESTING
JASPER live tests every popular Complete domestic engine with recorded inspections of temperatures, oil pressure, vacuum pressure and compression. Import engines are tested for correct oil pressure, compression, torque to turn and proper oil pump operation. JASPER's testing is one of the many ways we assure your satisfaction.

STATISTICAL PROCESS CONTROL
Processes are continually monitored through Statistical Process Control to assure accurate machining, smooth engine performance and complete customer satisfaction.

HYPEREUTECTIC PISTONS - makes pistons highly resistant to scuffing and chafe for long piston life.*

 

TORQUE PLATE HONING - reduces cylinder distortion and fatigue for long engine life.

 

MOLY PISTON RINGS - the hardened outside surface is abrasive-resistant for long ring life.

 

GRAPHITE HEAD GASKETS - highly heat resistant to reduce the chance of gasket failure.

 

MANLEY HARDENED CHROME PLATED VALVE STEMS - hardened chrome on valve stems to produce a smoother surface in order to prevent guide scrapping and provide long guide life.

 

CASE HARDENED CRANKS - a hardening process that gives the journals a harder surface to resist wear from the bearing during adverse conditions. *
