Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / April 2008leak detector dye
I bought some UV leak detector dye to try and pin down an engine oil leak. I put double the amount of dye in the oil as instructions call for because I'm just not finding anything that glows. I am using a "glow in the dark" florescent light as my UV light source. I'm not seeing much glow in the dark as far as finding the oil leaks. I have to get the light VERY close to see anything seemingly "glow' and it's so close I can't really tell if it's glowing or if it's just the light reflecting. Has anyone done this and is there some special type of UV light needed that's different from my dime store UV florescent?? |I bought some UV leak detector dye to try and pin down an engine oil | leak.

Does your light make the dye in it's bottle glow? How about your antifreeze?

I get oil dripping onto the alternator (lower right front of the engine). I thought it was the rear main but looking up the inspection cover it didn't really look like it was coming from there. I'm thinking intake manifold but was hoping to confirm it before yanking it off. It's a bitch to remove. | >...also, are you sure that you have an oil leak and not burning oil?

Is the oil being thrown up against the underside of the hood? >| >...also, are you sure that you have an oil leak and not burning oil?

Can't find any more hose leaks or pump throw off. > I bought some UV leak detector dye to try and pin down an engine oil > leak.

While the florescent light should work ok, a much better option would be one of the UV LED pen lights. I use a Coast "LED-Lenser Turbo Torch V8 UV Torch" I got from Fry's. It's a key chain type light that runs on several 357 button cells and is remarkably bright. Certainly a lot easier to get into all the areas you need to inspect than a florescent. Here it is for $10: http://shop1.outpost.com/product/3864717?site=sr:SEARCH:MAIN_RSLT_PG >> I bought some UV leak detector dye to try and pin down an engine oil >> leak.

I was just there yesterday !!! One of the problems with my current light is that its so darn big it is hard to get anywhere. >> I bought some UV leak detector dye to try and pin down an engine oil >> leak.

I can pull the dipstick and tell there's dye in that oil but I'm having a heck of a time finding the leaks. I thought the dye would may it light up like a firecracker. Only guessing, but maybe more dye in the oil would help.If/when you find the leak, it may be prudent to then change the oil filter and the oil.I dont know anything about using dye in oil. cuhulin > >> I bought some UV leak detector dye to try and pin down an engine oil > >> leak.

Pretty nice little light isn't it? Impressive how much UV you can get out of an LED. I've only used it with dye in the A/C and there it was quite easy to spot. As noted, perhaps you need a stronger dye concentration in the oil to make it more visible. Perhaps just visit the local car wash in the evening, pressure wash the engine clean and then inspect in the dark when you get home. > I bought some UV leak detector dye to try and pin down an engine oil > leak.

Try some yellow colored glasses like shooters glasses. Most UV dye kits come with yellow goggles of some sort, the one UV light I bought years ago that didn't come with yellow goggles had a yellow lens on the lamp housing. Regardless of the color, the goggles that come with with UV kits are designed to block UV light, which is harmful to eyes. Many of them are yellow because they also block blue light. > Try some yellow colored glasses like shooters glasses. > Most UV dye kits come with yellow goggles of some sort  SignatureMike Walsh > I bought some UV leak detector dye to try and pin down an engine oil > leak.

First thing to do is pull the oil filler cap or dipstick and shine the light at the oil and see if the dye shows up. Once you know what it is supposed to look like it will be easier to find the leak. |
