I observed a small amount of air bubbles coming out of the hose in the coolant recovery tank when the engine is up to operating temp. and I've had to top the tank off in the past couple days. Engine runs great and idles fine. Checked out the oil and no milkshake yet. However, I noticed some moisture buildup under the oil cap. Does this sound like a blown HG? Haven't done a compression check yet. Hopefully it's not a cracked head. <img src="/forums/images/graemlins/frown.gif" alt="" /> On a positive note, now would be the time to consider upgrading the cam. <img src="/forums/images/graemlins/lol.gif" alt="" />
