If you pressurize the entire system and then isolate it with a good valve you can leak test it without all the mess of dripping oil. Use a brush and some of your kid's bubble blowing liquid to check every fitting for "slow leaks". BTW, The "Red Oil" MIL-H-5606 has an additive Tricresylphosphate (sp) which is a carcinogen so keep your gloves on. Regards Brent
