Blue smoke=residue from cat converter?
Tuesday, December 16th, 2008I have a 1995 Hyundai excel, drives fantasticlly, 160′000 kms. for 5 months it had blue smoke from exhaust after long idle, pretty much several times a day, very stinky!
Got valve seals replaced 4 weeks ago, mechanic said there may be residue for a while.
Drastically improved after one week, now it’s apparent maybe twice a week after very very long idle(barely there).
I also have a “dirty” catalyctic converter because of the oil burning prior to seals being replaced. Could this remaining blue smoke be a clump of oil still sitting in old cat converter burning after idling as it heats up???????
BTW, Im not burning any oil. But before it ever started to blow blue smoke It got low… but now its been fine for months…. just hoping it to be resi in cat converter! Its such a reliable car- dont want to part with it!
