Block Oil Passage Restrictor Sets with DOUBLE SEAL VITON O-RINGS. EZ Install. All 101, 105, 115 Engines
[RKB-2]
$29.00 $27.50

IMPROVES OIL PRESSURE AT CRANKSHAFT

KIT CONTAINS

  • 6 EZ Install Brass Oil Passage Restrictors.
  • UPGRADED TO DOUBLE SEAL HEADGASKET O-RINGS.  These new design o-rings are "H" shaped cross section with two sealing lips, instead of crushed "o"ring.

Too much oil pressure bleeds off at the six cam shaft journals. the six block oil passages are 5.3-5.5mm diameter. Our custom brass restrictors reduce this to 2.5mm. The reduced volume to the cams is of no consequence. The increase in volume and pressure to the crank bearings is significant.

UNLIKE ROLL PINS

  • EZ Install - No Tools Required
  • EZ Remove - For Cleaning Oil Passages in Block
