Doing a cold compression test is not accurate,when components are cold they are in a contracted state,thus giving lower compression readings. Warm the engine up to operating temperature. Pistons etc will expand and give you more accurate readings.compare your hot and cold to see the difference it makes.the hot readings are what you have driving,which is the true picture. Would be interesting to see the difference on #3. If you do have new valve seals then I suspect rings are the issue. Check your pcv system and make sure it's not plugged or the valve isn't gummed up.
