Answer #1joelburke26 from Joels Auto Service, September 05, 2013, 04:07Master
quick n easiest way is to buy a small u/v die kit at your local auto parts store.you just pour in the dye where the oil goes n run the engine five minets or so then look for the dye with the u/v light n amber glasses.the dye will appear flourecent green where its leaking.others may suggest you spend the rest of your life washing the whole engine down to see the dye but thats not the case.most common place that vehichle leaks oil is the passenger side valve cover,very difficult to see if its leaking by the firewall unless you have an inspection mirror.
