OS .21 VZB V-Spec compression?
Hey all,
Just wondering how much compression/pinch my V-Spec should have. It's a second hand car/engine, so I don't know what a new engine should feel like. At present, I'm able to wind the engine all the way over by hand. With the plug in, it provides obvious compression over the top, but with the plug out, I can wind the engine over fully without feeling any 'pinch' at TDC. Is this normal, or is it starting to get worn out?
