Something Exploded...Help!

[BlueduckFSJ]

I picked up the Jeep from the shipping yard today. I started it up and let it warm up for a few minutes, shifted into drive and headed on my way. I pulled out of the parking lot and drove a quarter mile and I started to smell oil burning and light white smoke followed, and then smoke was coming through the AC vents. I pulled over immediately and popped the hood. There wasn't a cloud of smoke that came out, more of it was in the cabin area. I gave a sharp eye at all the areas, hoses, and such in plain view and checked them. Then I checked the dip stick and not a drop showed, so I looked around the air filter and noticed tranny fluid was ejected everywhere and puddled up in the grooves of the intake manifold. Then, thanks to the rain, I noticed the oil was leaking in droves. I poured a quart of oil in and in about 15 minutes it seemed a quart was already disspelled and draining into the side street. That is when it started to rain really hard and it didn't give up after that. I wasn't able to get under the truck to get a clear look at what was wrong, as there was a severe thunderstorm in the workd. Could anybody help me identify what the hay happened? The theory is that the real main seal was going out and engine oil was overcrowding the tranny. Any other theories as to how my tranny fluid ended up expelled by my air filter and my oil running empty? Due to the crazy weather I can't do a check out, so it is bugging me. Any help would be awesome! Thanks!

This might be off, but I experienced the same tranny fluid problems in a rig I owned a while back.
I was driving my rig to town one day after doing some engine work (the hood was off) when suddenly my front window became covered with red fluid! After flipping on the wipers I pulled off the road and assessed the situation. What I found was the tranny cooler lines leading into the bottom of my radiator had ruptured, allowing tranny fluid to spew onto my fan and subsequently, all over my engine compartment! Thank God my hood was off! I suppose if it had been on, the hot engine would have cooked the oil, producing smoke. Maybe your problem?
Could your engine oil loss be your rear main letting go at the same time? Murphy's Law and all!

On your tranny, there is a vent (can't recall the tech term) that sometimes gets plugged causing pressure inside the tranny and spewing fluid out the top of the dipstick. I have had this happen in snow and the vent froze causing it to happen. Unable to guess about your oil leak - Oil filler cap on? Mine has popped off a couple of times and caused a little smoke at speed, but not enough to cause a massive leak like you describe.

"I picked up the Jeep from the shipping yard today".

Did you just purchase this Jeep ? And did you purchase it as is ?

If you answered yes to the above two questions, ask the guy you bought it from, he probably has a good idea whats wrong with it, ie why he sold it.

Tranny fluid in the air cleaner is a ruptured vacuum modulator...IF you have the Turbo400 tranny, 72-79.

Oil leak is probably unrelated. If the PCV valve sticks shut or clogs, crankcase pressure can overcome the front or rear crankshaft seals. Remove the oil filler cap and see if the oil leak remains. If not, then suspect the PCV valve. My old '83 J20 had so much blowby, it was too much for the PCV valve to pass and pressure built up and forced oil out the front seal. When I removed the oil cap, the leak was fixed!

Thanks for the input fellas...it didn't rain today, so I checked it out again. As it turns out it was only transmission fluid that was ejected. Most of it was colected in the grooves of the left intake manifold next to the tranny fluid dip stick. I did not see any oil at the time, just tranny fluid. I believe the fluid was burned and that caused the smoke that went through my ventilation system and into the cabin. I still have not been able to figure out the problem. Given there is no oil ejecting, do you still think the best bet is the rear main oil seal?

As far as the oil leak. Can you tell if it's leaking from the front or rear of the motor? If it went through a quart in a few minutes it might be a stuck spring in the oil pump creating to much pressure or the pump may be blown pushing oil out . Had both happen to me.
