Oil dyes? Use them or NO??

I am still trying to trace a few leaks. These are on the right side of the engine. Anyways I have cleaned it to look, but as I drive the car the oil of course spreads.

Can I add the dye to the oil then just let the engine idle until it starts to leak a bit? I hate to warm my engine up or let it idle for long periods though.

Wondering if either will do harm.

I've used it. It is truly amazing!

When you turn the lights off and shine a black light on the engine, the dye lights up like you can't believe. Makes pinpointing leaks very, very easy.

Can't imagine that it would do harm. Its been around for years, and its a tiny bottle of dye. I didn't worry about it.

Thanks, so did you add it then drive or just add it then let it idle or what?? I just find when I drive the oil can go everywhere.

I went on a drive before adding the dye. Let the car warm up. Then added the dye and let it idle a few minutes, in the dark, while I looked for the tracer dye with the black light.

Perfect thanks, so it just took a few minutes. That stuff must be good.

We have used oil dyes to track down leaks in industrial engines for years. The quantity of dye required is very small and will cause no harm if used in small amounts. The dye kits are available at any regular automotive parts house like NAPA, etc. Good luck!!
