Maybe you ran over this stuff on the road, is it anywhere else (wheel well) other the the firewall?

 

No its not anywhere else. I am still working on getting a picture because I cleaned it off but I'm almost positive it is back again lol I just havent checked yet.

 

the one color is closer to a black but when you put it on your hand it is a oily clear residue.. but when packed together it looks very dark (blackish). so sure the one is black, the other is far from it tho..

 

Thanks for the advice man. I cleaned everything up this morning then drove for about 20 miles and it's still clean. This leads me to believe that it definitely was a rip in one of the boots (either the axle or the rack and pinion). I guess all of it is out so no more is flinging out. I still don't know which one it is because I have ran my fingers through every groove on each both boots and I didn't feel any rips or tears.

 

This sounds goofy to me. I had to replace a boot on a Mitsubishi (not an Evo) and several weeks later I looked under this car and their was grease everywhere. Now, the boot wasn't split, it was just leaking out through one of the clamps. The grease that came in the kit was light yellow, almost the color of cream.

All the splatter was right in line with the boot. The axle will fling it out in a straight line at right angles to the boot and there will be lots of it. Also the boot was gooey with grease. So, if this is occurring, it is child simple to see.

 

stop driving on it!!!! if it is really the axle grease you will destroy your bearings if you continue driving on it. if its a tear you're not gonna see it until you get under the car and thoroughly inspect it.

 

did you check both boots? inner and outer? if you thoroughly checked the boots and you see nothing then maybe it is not the axles then.

 

Yeah I checked all of the boots. I'm actually thinking that maybe it was just some grease or oil that got on the boots when the shop was changing out my tcase and when the grease got mixed with water from driving in the rain it might have changed to that color like one of the other guys on here said.

 

second best post man am I glad I read the forums today this is great.

Any pics of engine bay before you cleaned it all off the firewall?

 

No sorry I dont have any pictures. The second test will be today. I have to run a couple of errands close to my house so I will keep checking it everywhere I stop and see if more goo is in the engine bay. If it isn't then I guess I will go from there to look for other possible causes or maybe it was just a freak occurrence.

 

I had this "butter" colored stuff sprayed on my firewall and under my car from the axle not being seated all the way in the transmission. gear fluid all over the place coming out of the output shaft. Mine was on the drivers side. knocked it back in with a rubber mallet and no more goo. check to see if there is a gape where it is seated on the passenger side. hope this helps. good luck.

 

axle boot

 

I actually noticed some play in the pass side axle. I can move it a little bit side to side so that could be it. I pushed it in as much as I could into the tcase and maybe that's what stopped the leak.

 

how loose was it? were you able to give it a quick jerk and hear or feel it push in further then before? it should be a few mm away from the tcase/trans at best.. tiny play..

if yes to the first thing i wrote, then top off the tcase again.. there should be enough fluid in the tcase that it spills over the fill cap.. dont worry about overfilling it, it will come out the drive shaft end if its overfilled.. plus the tcase and trans both have pressure reliefs / drains incase people do overfill them.

did the stuff smell really bad? another thing you can do is buy some of the gear oil and compare the smell to what you had on your hand to get an idea what it is. gear oil has a horrible odor.

 

Happened to my friends car as well. It came out the valve cover and looked like diarrhea....
