my b16a starting smoking at a light, and then when left the light to park it around the corner it started to bog, I thought i lost compression or cracked something. feels like im running on three cylinders.

I just noticed a crack in my headers

is it more seriouse Ie.. engine related? or It can be solved getting some new headers???
(i hope, need some 4-1 anyways)

 

Do a compression test.. It will let you know a lot

 

Header. Singular.

Compression, leakdown, and block tests should all be done.

 

In your thread title or first post, you MUST mention what car you have.

 

white or blue smoke? you could possibly need a new head gasket
