Welcome to 2CarPros.
Most likely you have a blown head gasket. I would start by checking for evidence of a head gasket leak. Here is a link to help:
https://www.2carpros.com/articles/head-gasket-blown-test
If you determine the gasket is bad, here are directions for replacing it. You indicated a 1.5L That wasn't an option. Either a 1.6L or a 1.8L were available. So, I will provide directions for both. First will be the 1.6L. The attached pictures correlate with the directions. Also, there are a lot of directions. However, you will only need the one related to your engine's size.
