Temporary fix for leaking valley of asphalt shingle roof

Hello! I have an asphalt shingle roof that is leaking from somewhere along a valley (or so I suspect). I have plans to re-roof the house this fall or next spring, so I'm seeking a simple, affordable, temporary fix. Is it possible to coat the top of the shingles in the valley with a substance such as tar, and have a desirable effect?

For a short term fix, yes, tar will work. But not simply covering the top of the shingles. You need to work it into any cracks or tears along the way and try not to create any dams that would stop the free flow of water. Get the type tar that can be used in wet conditions so it can be applied to wet or dry shingles without worry.
