My oil & exhaust smells like gas. What to check/replace?

Please send your idea's on where to start.

could it maybe be too rich?

exhaust smelling like gas would tell me it isn't all getting burned up.

Faulty catalytic converter?

Injectors stay open when you shut the engine down. Watch the consistency of the oil - if it starts getting very thin and "gas-like", you've got yourself gas mixing in with the crankcase oil.

We recently scored a nice XJ for super cheap because it had the same problem. Turned out to be a dead plug :yes:

 

I'd definately make sure it's firing on all 6. An injector stuck open could likely cause the same symptoms though. Not sure how rich you'd have to be running to get the gas in the oil otherwise.
