I have no connection with them, however I type “dye to check for oil leaks” in Goggle’s search and found this link http://www.tracerline.com/faq.html

There may other brands of engine dye oil leak tool, if so please to inform me or us.

I thought to add this information to yours sort of references.

Look down to “What kind of leaks can it find?” and “What types of fluorescent dyes should be used?”

Jerry,
As a mechanic who spends hours each day chasing oil leaks I have tried just about every dye and light combination and in my opinion, they are all worthless. If the motor is so filthy that one must use dye, chances are that the dye will just leach into the oil already spread all over the engine and all you will ave is a lot of oil mess which responds to light. Steam clean everything, spray suspect areas with brake cleaner and once it is dry, start the motor again and look fior the leaks in the area you had drips.

Good luck,

Chris

Chris: Have to agree. Tried it a couple years ago on an 8-71 I helped with rebuilding. After several attempts of cleaning and re-starting the engine, I finally climbed in and found the leak with my eyes--used a steel washer where we should have put a copper one. The engine was DD green and the dye was a sort of florescent green and where you could not see it, followed a casting ridge from the actual leak but the dyed oil was actualy leaking against a gasketed flange and tracing around to another area.

Sure the dye might work in some cases, but like Chris the combination of steam cleaning and brake cleaner works for me.

Plus, if you do a good job of steam cleaning, and find your leak afterward, you'll have a clean engine for a while.

I've used dye to good effect on several engines. When the old crud has been baking on for 20 years, NOTHING short of a machine shop's hot-tank or a sandblaster will remove it. Obviously, you want to use dye that ISN'T the same color as the engine.
