I went to start my car today after having the engine rebuilt I put the motor back in myself but when I went to start in my dad noticed a oil leak checked it out and I seams to be coming from an access panel on the transmission but it only leaks if I turn the ignition so I drained the oil and nothing but fuel came out Im sure I mixed up some hoses somewhere but was wondering if anyone has had or herd of this problem before I tried looking it up first but can't seem to find anything any help would be appreciated

 

Does it just smell like fuel? Or have you somehow proven it's fuel? I would suggest taking a small amount, like a teaspoon of the fluid, and take it outside away from flammables and try to ignite it. If it's mostly fuel it should ignite very easily and burn fairly thoroughly. If it's mostly oil with some fuel it may ignite, but would probably die out leaving most of the oil unburnt.

Understand that this problem sounds absurd so that's why I want you to determine for sure what the fluid actually is. However, lots of fuel in the oil is never good, so even if it's mostly oil you may still have big problems. If you have very leaky injectors and poor oil seals you could get a dangerous amount of fuel in the oil.

 

Wait, are we talking about engine oil or transmission oil?

Either way, blowby is expected in piston engines not rotary, this is either a mistaken diagnosis, or something is seriously messed up.

 

I get small amounts of gas in my oil, but it may just be because the premix gets past the seals with a little gas still in it.

However after rereading his post I think he might be saying there's gas dripping off the trans oil pan. If that's the case there's probably a loose gas line. Check all your fuel lines and use the proper clamps. Screw clamps are NOT proper gas line clamps. Don't ask how I know, I'll tell you, it caused me an engine fire. If it's not a loose fuel line it could be a leaking pulsation damper, improperly seated injector, severed fuel line... in rare cases a fuel rail could be broken.

DO USE THESE ON FUEL LINES

It's engine oil it's coming from the rear engine seal and yes fuel lots of it about a gallon and a half talked to the mechanic that rebuilt the engine and he says that the car is getting so flooded with gas that it got into the oil so I drained everything and I'm going to bring him the car next week hopefully none of the seals got ruined

 

If you have that much gas in the oil it sounds like the fuel lines are mixed up. I believe the charcoal cannister vents to the crankcase, so if you mixed up the vent and pressure lines that could do it. Somebody had this problem on a first gen a few weeks ago and it turned out he mixed up the pressure line with something else and was dumping fuel into the crankcase.

If it comes out when you turn the key on without the engine running then that sounds like this is it.

Unfortunately, if you dumped that much gas in the oil the oil is NFG now, correct the lines, drain the oil, refill, run it a few minutes and drain again then refill again. Run a very short change interval (a couple hundred miles tops) and change it one last time, then you should be good to go.
