Concerned about my exhaust
I have a 1993 del sol SI and it has a magnum exhaust pipe on it. today after church I was letting a little kid sit in it and rev. the engine. he wasn't being hard on it but It was hitting the redline. anyway, I notice a little puff of black smoke would come out when it would high rev. is this normal or should I be concerned about it? and is there anything I can do about it? Thanks guys.
it seems to only blow out a puff of black smoke whenever it has high RPMs. like whenever I drive it fast which is very rare or i guess whenever someone revs. it too high.
I've seen "brand new" gto's and saleen's do the same thing off of dyno's, it's normal...as long as you're not smoking all the time and burning a crap load of oil.
