They leak at all boost because of the metal piston to the aluminum seat, but the amount of boost leaked off is negligable for the price. Tial and greddy and maybe hks use a seal between the valve. But greddy leaks from other places and hks can be sealed up and work properly but the outlet is a limiting factor like the 1g and evo mr bov valve size. Tial is the best for sealing and flow if you use the correct spring, as to cause the least amount of surge.
Steve, good progress. The ton of coolant in the cylinders is from not draining the coolant completely, I’m not doubting a headgasket failure but just letting ya know. Oh and give me those tools, I could use an extra set.
