Today was the worst day on my way home I notice a cloud of smoke behind me I could'nt pull over to the side no shoulder so I drove the jeep for about 5mins more before pulling over open the hood I see oil pouring out of the oil pressure switch. went to autozone got new switch install start the car no leak. Now I don't know what kind of damage I done to my engine I6 90YJ but what should the exhaust color be if I'm burning oil or coolant. FYI car did not over heat.

as long as you did not dump all of your oil before you replaced your pressure switch you should be fine. How low was the oil. The smoke probably was from it dumping on your exhaust.

My advice, get a good oil change done with new filter and then pressure wash the underside and lower engine bay to get it all cleaned up. If you blew your head gasket, you would have white smoke coming out the back and you probably would have overheated.

When I stop and check the oil I couldnt tell from the dipstick oil was everywhere so before I restarted the jeep to check where the leak was coming from I Pour about 2.5Q on it thats when I saw where the oil was pouring out. Turn it off got the replacement check the oil good restarted no leak drove home fine. I guess tom. is the only way to really tell if any damage was done.

I had the one in my '83 Cherokee (full size) do that. I thought it was the rear main seal, so I spent the night of New Year's eve '99 changing it. Didn't see any leaks, so I drove to Canada and back, but I had to stomp on the gas to merge on I-5 at Bellingham. About 30 miles later I heard a horrible knocking noise.
I put 3 quarts in and saw it was leaking. First time in almost 40 years I didn't have tools with me so I finished driving home. I stopped every 10 miles and added another 2 quarts, but my case ran out 25 miles from home. I dropped my son's then GF off and said screw it! If it blows, it blows! (3AM on a sunday night)
I got home and shut it off as I cruised into the yard. Next day I filled the oil and swapped the sender. Didn't lose any more oil, but the 282 (Mexican six the stroker was based on) was shot. All the pistons had chunks out of them when I stripped the motor down.
