91 camry - oil leaking a drop every 4 seconds. Also upon start up there is (was) an intermittent whirring noise, possibly a bearing? Oil appears to be dripping from below the alternator - behind the timing belt cover Obviously its impossible to pinpoint the leak, but It would be great to know worst case scenarios ( I love the car but not enough to spend $1000 ) and if this is a job that a fairly handy guy might be able to tackle - thanks!
