Material & Construction
This component is machined from solid 6061-T6 billet aluminum rather than cast or stamped from sheet, which is why engine builders trust JayCee oil-system hardware on both street and performance air-cooled VW builds. Tighter tolerances at the sealing surfaces mean fewer weep leaks over time compared to lower-cost stamped alternatives.
Installation Notes
Always install with a fresh o-ring or gasket as applicable, torque fasteners evenly in a criss-cross pattern, and re-torque after the first heat cycle. Check for seepage at the sealing surface after the first drive and before every oil change thereafter.
