Zugara Posted October 24, 2010 Share Posted October 24, 2010 Ok, I have noticed of late that one side, LHS when looking at rear, of my exhaust has more soot in the tail pipe than the RHS. Has anyone any ideas why this could be. I have no tick-over issues, 500rpm steady, no difference in performance, no miss-firing and all seems fine with the engine. Anyone know where i can get a decent tune up in Fareham area. Or at least get the car looked at by a decent motorhouse? Quote Link to comment Share on other sites More sharing options...

ATTAK Z Posted October 24, 2010 Share Posted October 24, 2010 Remind me , are you on a true dual ? Yep, HKS replica... Could be oil is getting into the LHS cylinder bank either up past the rings or down the valve guides Quote Link to comment Share on other sites More sharing options...
M13KYF Posted October 24, 2010 Share Posted October 24, 2010 or one of the cats going/gone. Chesterfield has the same issue and was advised that this could be the problem with a true dual (original) Quote Link to comment Share on other sites More sharing options...

andlid Posted October 24, 2010 Share Posted October 24, 2010 does the hks not connect anywhere on the way down from the cats? (pressure equalisation) Quote Link to comment Share on other sites More sharing options...
Zugara Posted October 24, 2010 Author Share Posted October 24, 2010 does the hks not connect anywhere on the way down from the cats? (pressure equalisation) Not as far as I am aware, Straight run from the manifolds to the tips. I had this problem with my OEM one as well, but wasnt so noticable.

I had this problem with my OEM one as well, but wasnt so noticable. hmm lets just take a gamble and state that it could be the breather pipe for the intake pipe popping oil into the 1,2,3 cylinder and thus burning oil for the left exhaust pipe only? (I'm guessing big time here...) You could open the plenum and see if it's dirty with oil there... (ever cleaned it?) You could attach a oil catch can for the two breather hoses and see if it dissapears? Have you changed the plugs? Quote Link to comment Share on other sites More sharing options...

Sparks have never been replaced as far as I am aware. I only have 19k on the clock though. I dont seem to be using any oil either. Quote Link to comment Share on other sites More sharing options...
Darren-B Posted October 24, 2010 Share Posted October 24, 2010 Unless you have excessive oil consumption I wouldn`t worry about it, besides it would likely to be coming though a weak/damaged piston ring rather than through the plenum so check the tips of the plugs if your really worried. Personally as previously mentioned I would go with a dodgey CAT or perhaps the left hand silencer has fewer baffles in than the right one Quote Link to comment Share on other sites More sharing options...
