I just completely put my engine back together and am sure i tightened everything. After about 10 minutes, I noticed oil on my exhaust pipe again. How did it get there. Is there a small hole in my fuel line or is it coming from my carb?

check your fuel lines look for a pin hole

is it on the pipe or on the header? if it is on the header, check your header gasket for a leak...

I just retightened the header before this. How would i check for a pin hole in my fuel line if i can't see it with my eyes?

Blow through it like you would a straw or just replace it. While you are at it you might as well check the fuel tank and fuel cap for air leaks. The cap has an o-ring under it that can be tightened. Some of the older fuel tanks also have a primer which is known for air leaks--I guess that is probably one reason Traxxas replaced it on the latter T-Maxx 2.5s.

Just a suggestion clip off the zip ties on rubber coupler and install new zipties and cinch them down very tight
