my friend has a 98 4 door with a d16y7 and a jackson supercharger, he had me look at it last night because it started smoking really bad and #1 cylinder was missing. its getting spark but it has no compression and theres oil in his coolent.. what all would do this? blown head gasket, cracked head?

 

No Compression and oil in coolant... Headgasket!

 

thats what i told him but i just wanted to see what all my honda friends thought!
thanks
