    Да ладно бы один случай. Два комплекта клапанов. И оба так себя так повели и именно выпуск. Впуск стоят четко.

    Did you install the valves without any prep work? Did you LAP the valves?

    I don't think it's the valves fault on this one. These valves have been out on the market for a while. Pretty safe to say there is probably an issue with the install?
