Hey guys, I'm new here. My name is Sam.

I'm stuck with my engine. It's a b20a and recently it broke down. So now when I start it it is missing like crazy, and then slowly dies, and some times there's a puff of smoke coming from the inlet manifold.

When I turn it by hand, I hear the compression in the engine but then it sounds like it,s being forsed out so I hear this whoooosh. I suspect it might be one of the valves not sealing. Please help me

Has any one here had this problem before.
