Oil in radiator

[mrsn95guy]

I have a turbo car and it’s down on power doesn’t feel like it’s pulling hard. I’m having oil mix with my water in the radiator there is none mixing in oil pan, how does this happen? I’m worried I have a split block although I’m not entirely sure, would it decrease combustion process robbing power?

Gotta do all the vital checks. Compression check, leakdown, and examine the plugs.

A simple sparkplug examination can tell alot. Every cylinder, the sparkplug should look the same. Usually a weird cylinder will show on a plug reading. I know this doesnt answer your question, but will help you narrow down where the problem might be.

Are you sure it is oil, not carbon black crud from the exhaust? The carbon can be caused by a cracked head or a bad head gasket which results in combustion gasses being blown into the coolant system.
