2007 335i BLUE SMOKE PROBLEM AFTER CATLESS DOWNPIPES

tibra1 · 06-03-2011, 12:26 AM

I have an eclipse N/A that had blue smoke catless...n stank..i think it has to do with health of the combustion cycle.car had 165K..catless on my 335i 17K and no smoke at all..how many miles u have?

blue smoke is indicative of burning oil, so cats would not fix the problem, maybe only mask the symptom. I would monitor your oil levels VERY closely!

yea im pretty sure its burning some oil w 165K on it..

That's the same problem I'm having... only on the left side.

Any other advice, other than changing out the turbos?

This is almost certainly leaking turbo seals....they have to be replaced. You may find someone who can do a turbo rebuild for you for a decent price.
