Coolant into oil

Hello,

This is a problem with your head gasket. Your vehicles engine block and cylinder head have both oil and coolant galleys in them where they pass both fluids from one to another. when your head gasket blows out it allows these two liquids to mix. I have included a few links for you to go to down below.

We already change the head gasket and it does the same thing again.

Hello again,

Okay, I hate to be the bearer of bad news, but it sounds to me like you have a crack in either your engine block or your cylinder head, I would lean towards the cylinder head, allowing the coolant to mix with the oil. If you had a head gasket replaced at a shop, they should have shaved the head to true it up and also pressure tested the head to make sure it had no cracks in it. So, if you had it professionally done, you can almost bet that that engine block is cracked. Please let us know what you find out.

Thanks,
