Sounds like the seal on the crankshaft has failed, the smoke is probably from oil blowing back on the converter....I have a 1996 jeep cherokee, and today it started to leak oil and my catalytic converter is smoking, help?
It is possible that your valve cover leakage. There are a lot more seals on the engine that can leak. From oil pan to time chail cover.


If the oil runs down the exhaust, then it is most likely valve covers.


Hope that helps.
it could be 2 problums, One your spark plugs are not firing at the right time, or you could have your head potrs leeking. First chek all the spark plugs and then open up your rediator cap, and look if there are any white stuff in the rediator? If there is then your head is leaking.
I had a jeep cherokee, they are renown for their tendency to leak oil. From what I understand it generally comes from one of two places. The valve cover (gasket) or the crankcase seal.





Try tracing the flow of oil. hopefully, it's the valve cover.

The converter smoking is most likely is blowback and the oil leak would have to be physically searched for. Maybe if you started from the oil pan and worked your way up you'd find the oil leak.
