so i went to put some oil in the FD today, and there was an orangish brown looking gunk on the underside of the cap.... please tell me i didnt blow a coolant seal!!!!

oh and i dont know if this will help. but the car wasnt started for almost a month before i seen this, then i drove it for 2 weeks went to put in some oil and this was under the cap. and before i left for that month.. this wasnt there

As long as the oil on the stick is good to go you're okay.
condensation gets inside the motor and most of it boils off after the engine gets hot. I've had it happen to me on my oil fill cap of my old Doge and I freaked out just the same.

wipe it off and keep an eye out.

 

i dont think you two guys realize how happy you just made me... thank you a lot

if you ever need aftermarket parts let me know, ill hook you up
my business name is superior high performance and im launching the site in march
but in the meantime i can still get you whatever you need.

thanks again to both of you

 

Thats the funny thing about owning these cars. Whenever something goes wrong related to the engine, we always assume the worst or at least it crosses our minds.

 

I have the same thing. Lots of gross foam filling the oil filler neck...

 

mine isnt quite that bad... it was just on the cap and a very very thin film on the neck... and it wasnt white, it was orangy brown

 

Well that kinda scares me... except that I take meticulous care of my car, and it runs excellent.

 

How long have you had the car? The color that you're describing makes me think of that copper radiator filler, people pour it in to try and make it not smoke after blowing a coolant seal.
