i found the perfect thing to find leaks while working at the tractor dealership ..they sell a blue pen lite ,,and when you shine it on the oil it glows green ... you can wipe the area clean ,, with some carb cleaner ,, start it up ,, and shine the lite on it ... you will see a trail of florescent green oil start to flow .. they sell the blue penlights at any auto parts ... the cost is around $20.00 for them ,, but well worth the money ...try it ,, you WILL be amazed....
