Took my xj out on the high way for the first time in 2 years and it smoked like crazy . I topically only drive it on short trips and never noticed it before I know I have a oil leak some where so it could be coming from that ill have some one tail me tomorrow to se if its coming out the pipe or under neath . I don't know . It seems to me I'm becoming a car expert , by the time I get this thing off the road and onto some dirt ill know and have touched each part

 

Wipe your finger inside the tailpipe (oh stop it, you know what I mean) and see if you have fuel, oil, soot...

 

See if you can find some punctuation in there too. You seem to have lost quite a bit of it.

 

I put my hand under the tail pipe to see if any thing was coming out I got nothing . Ill finger the tail pipe some time today . I hope it's as good for her

 

Black soot and a lot of it

 

O2 sensor.

 

It really helps if we know what you have. If you fill out your info, it's there in every post.

 

LOL!
