interior engine questions
I have a .15FE, and as much as I want to get a new engine my wallet isn't up for it so I have to make this one survive until atleast christmas.
Lately is has been leaking ALOT! enough that it drained 3/4 of a tank of gas while sitting on my driveway (angled with the rear of the truck down) I know for a fact that it wasn't fuel lines because the oil/mess didn't start until the back of the block. B]what could be the cause of a leak that starts right behind the block?[/B]
also, since I decided to take the engine appart (mostly to see what a nitro engine was like inside, and to see how mine looked) I noticed that the pull start string is all black and oily. how could it get oily? an where ever the oil stuff is comming from it leaked all over the chassis right where the pullstart, back plate, and the block meet. so which of them is the problem? it seemed like there was way more black in the pull start side of the back plate but i dont know how it would have gotten so oily.
and last but not least, the interior of the engine is stained. If i remember correctly castrol oil leaves the dark brown stains, and i am pretty sure wildcat (which is what I am running) also uses castrol oil. is there a way to remove the stains from the inside of the enigne? the stains are on the pilot shaft (where the carb goes and where the rod connects) the whole rod is also a bronze color but I dont know if it comes that color. OH, and how do I remove the same brown colored stains from my exhaust header? it is VERY ugly but I just cant seem to get them off.
thanks in advance for any and all help
