Overview

The Isky Racing Cams Groove-O-Matic Cylinder Block O-Ringing Tool is designed to "O-Ring" the cylinder block face, preventing blown head gaskets in high-compression, supercharged, or turbocharged engines. It pilots in the cylinder bore and is easily adjustable for both bore diameter and depth of cut for the copper O-ring groove. This tool provides a fast and profitable way to O-ring cylinder blocks. It is a full-size tool suitable for V8 engines with 3-3/4 inch to 4-3/8 inch cylinder bores and includes copper wire and instructions.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
