Hello,

I noticed some sort of fluid leak in my garage toady not sure what it is and i dont think its oil. Its not a drip but acctually like a strip. Just for some background info my cousin recently changed the slave cylinder could this be the source of the leak if a bolt wasnt tightened properly. Its seems to be coming from the center middle of the vehicle. Any help would be appreciated.

what color is the fluid ?

could be powersteering or transmission oil ...

coming from the center middle of the car leads me to beleive it is a oil leak,

check ur oil level daily and see if you notice a diff, also take ur timing belt cover off and see if ur cam seals are leaking

could be crank seal as well

Depends if your doing it on ur own, or having a shop do it

When you do the timing belt next id recomend cam seals and crank seal to be replaced

other then that try to pin point the leak clean the underside with degreaser
