smash on 3rd gear, now the car sound like a subaru and cylinder close to dizzy is 0 compression. all other are still 200psi. white smoke. oil in coolant and coolant in oil.
is this a sign of blown headgasket.

 

These are the exact symptoms of a blown head gasket. A simple search would have yielded you this information.

 

i did search but most of them still have compression, my clyinder close to dizzy has no compression, did a wet test with oil still no compression. sure this is blow gasket. if it is should it have at lest a little compression .

 

If you have oil in your coolant, and coolant in your oil ... it probably is a head gasket. Unless you blew a hole in your block.

 

HG, coolant in cyl. causes white smoke, time for a boost build, lol

 

either way it sounds like the head needs to come off... you will know if you have a hole on your piston, sunk sleeve, warped head, or whatever else when you get it cracked open. 0 compression would lead me to think worse than just a headgasdket

 

that what iam thinking 0 compression is scary me. hopefully its only a headgasket....

 

I think you have headgasket and piston damage. I've seen huge sections of headgasket blown out in Honda applications, pushed out the back of the block in DSMs, and still have some compression although it's super low.
