That, was a dam interesting read. I know what ill be doing if/when i rebuild.
Totally clears up why my mates Civic he rebuilt (12.1:1 compression, 306' cams, 10,000rpm etc etc..)
used to smoke all the time. He nana'd the thing for 5000km i believe, only ever hitting VTEC once. Blue smoke used to piss out during deceleration. Shame a valve snapped and cracked two cylinder walls/pistons not long after...
