1987 turbo, Need help diagnosing!!!

[dylansword]

Hello, I was driving down the freeway, and i noticed the temp was redlined. I pulled over, and let it cool. Started it again. It was missing bad, and blowing tons of white smoke. So i figured the head gasket. I was pulling it apart, and wen i pulled apart the intake, there was water in each port. I did a comp test, and it was, front to back. 125 120 120 120 150 140. The back two cyl hav oil in them. My question, is if it has good comp what is causing the problems. ( running rough, oil on plugs, and water in the intake, water in the oil, and overheating?) Any input would be great, I need to figure this out asap! Thanks
