P1124, P1126, P0446 and substantial oil leak

Recommended Posts

1999 Boxster with 105K miles is getting these codes, a little white smoke mostly coming out of rear passenger wheel well, and a pretty substantial oil leak below the car. At least I think it is oil leaking, it's black. Car is running pretty jumpy. Is this an AOS problem? Any ideas?

Thanks, Dave

White smole is usually water as in water in your combution chambers. Oil usualy burns blue out of the tail pipe, and black out of the tail pipe means its running to riche. should have CEL wich will tell you a thing or 2

With a big oil leak you could be leaking on to the exhaust naifold,,,don't know the color but I know it stinks. Sounds li 2 problems maybe. Leak and rough running. You miust have a CEL.
