Hi, I was wondering if anyone else has had this problem, my 33 was blowing a small amount of smoke for ages, it then started idleing lumpy, like i lost a cylinder, so i went the quick fix and put 2 iridiums in no.s 2 and 4, it ran great, and no more smoke!, i then changed the remaining 4 and had the miss back after one gear change, i pulled each plug out and found no. 6 black and wet so i replaced it, then as soon i got on boost and just after i got off boost heaps of smoke, thinking it may have been breather set up i moved a few things round because of my on going but newly magnified blow bi problem, no change. I then drove it 3 hours on the highway and it totally cleared up, no longer any smoke, but rough idle, adjusted air idle screw, then small amount of smoke, worried about idle still i dissconnected each coil plug.
and found 6 to be weak again, so replaced plug, now i got heaps of smoke but only on
decell, so dissconnected plug, no smoke and u guessed it rough idle. So iv worked out its
no. 6. So now knowing im fouling no. 6 and pumps out blue white smoke when connected is it, blow bi, scratched bore, valve issue, change to iridium plugs? Or just a unrelated sequence of events?
