whats wrong with the 13brew?
ok 97 13b-rew, 122kms, auto
when the engine is cold(havnt tried while warm) you rev the engine a lil, or alot(mechanics, go fig.) the exhaust makes a popping noise, and the engine fires black smoke out the back, can sound like machinegun fire at around 3-3500 revs, is this fuxored apex seals? or somthing cheaper
any diagnosis would be appreciated
cheers
