Case

Only late style dual pressure relief cases are used. They are first hot tank, then thoroughly washed by hand.  The cylinder base area is decked and  surfaced on a Bridgeport Mill to set initial deck height alignment between all four cylinders and and to eliminate oil leads at the base of the cylinders. Case inserts or "Case Savers" are installed, Align Boring and all remaining machine work  is done and then the case is thoroughly cleaned again and painted.

 Dual Port Heads

JCS buys thousands of head cores every year. A good portion of those are scrapped for the aluminum "scrap value" because they are too worn to be rebuilt or require too much work. We select only the best cores for rebuilding to insure a high quality, dependable finished product and to minimize the amount of labor put into rebuilding a head.  These select cores are then fully machined... valve guides are replaced with  manganese-bronze guides  designed for extreme wear resistance and improved lubrication.  All valve seats are replaced with heat treated chromoly  steel seats  that promote a quick,  high heat transfer rate from the valve to the cylinder head casting. 

New Piston & Cylinder Set

The preferred choice for 85.5mm Piston & Liner sets when building a VW engine. Premium quality.....

VW Connecting Rods

Late style 1600 rod cores are shot-peened,  sandblasted and checked for straightness. New wrist pin bushings are installed then rods are bored and honed center to center.

VW Crankshafts

JCS uses only 1600cc style "crossdrilled" crankshafts for it's superior oiling properties. Cores are shot peened,  sand blasted, then carefully inspected for cracks, straightness and damage to the dowel pin holes and threaded ends.  Cranks are reground to exact specifications,  micro-polished and a thread chaser run on both ends. 

 VW Flywheels, Reground German or New

Only German flywheel cores are first inspected for worn or damaged teeth,  dowel pin holes and clutch disc mating surface wear to make sure it has not been worn or cut too deep.  After shot peening and sandblasting the seal area is polished,  the dowel pin hole area is faced to ensure proper mating to the crank and then precision ground and polished to exact specifications.

Stock Style Heavy Duty Oil Pump

Made from die cast aluminum alloy the pump housing is fully machined to exacting tolerances. Larger 30mm steel gears provide increased oil pressure during low speed operation. Pumped oil volume is increased by 30% - 40% over stock promoting lower operating temperatures.
