Hi,

Often times when engine oil and coolant mix, you get a creamy sludge. Is it possible for you to take a pic of what you see and upload it for me.

Take a look through this link. It explains how to test for a bad head gasket. It shows pics of what it looks like when oil and coolant mix.

Also, if you could record it when you are trying to start it, I may be able to tell if it is a compression issue.

Let me know.

Joe
