Recently I went on a trip when i got home my 92 dodge shadow 2.5 was looping a little. when I uncoverd the valve cap a stream of white smoke was gushing out smelled like oil. I noticed that the smoke worstend as I put it in reverse and drive. I use 10w30 motor oil dose this mean I should change to 10w40 or higher or is the problem worse.

 

Today I removed the valve cover and noticed thier was no water in the oil. I also did a compression check every thing normal however the white smoke is coming out of the front deep crevases of the head. Also as I removed the intake pan which covers the tbi noticed thier was oil inside including next to the throttle body. I also saw some oil inside the intake manifold though the throttle body. Is my head cracked or do I need to change my head gasket or intake manifold gasket. Please help me. Thanks
