Random Tech Tip #38,2012. Got an oil leak you can't seem to find the souce for?
Here's an old trick for finding those pesky oil leaks. I read about this method several years ago in Easyriders Magazine and was originally used to find slow seeping seals and gaskets on an american made V-twin, but there's no reason you can't use it on anything that holds oil, has gaskets and shouldn't leak. After you spray the brake cleaner around and get everything all clean and sanitary, give it a little drying time and give the suspect area a coat of spray-powder deoderant. Once you get a fair coat of the white stuff all around, just run the engine a little bit and any leak even down to the slowest seep will stick out like a seagull at an Adam Sandler movie! (old Family Guy reference)
All bad similies aside, there's not an oil leak that can hide from this leak-finder method and will tell you exactly what's leaking and how bad.
