Check to see if there is oil in it & at the right level. If you can do a compression test to make sure that all cylinders are close to the same compression. Check dist. Hold down locking tab tight. How many miles on the heads.

Did you change the oil yourself?If not who did ?Is it the same place you always go to?Because it sounds to me you have got ANTI-FREEZE in your oil.It could be what Scott answered you.Or the person who changed your oil just did a NUMBER on your engine.HOPE NOT!!But you need to find out.GOOD LUCK!!
