2G Sanity check..would this cause an oil leak?

[smills1840]

I recently restored my 99' engine bay. All new gaskets on my stock 7 bolt long block.

As soon as I got it running, I noticed an oil leak on the timing side. After removing the timing covers, the oil pump sprocket nut fell on the floor. The sprocket is still on the pump, but just barely. Talk about a close call!

Would that nut being loose case an oil leak? ANSWER: YES, A LOOSE OIL PUMP SPROCKET WILL CAUSE A MAJOR OIL LEAK.

This oil leak is pretty bad. It has covered all of the suspension components and axle on the driver side, and I guess it's spraying off the timing belt up top. I've tried the UV dye to find the leak, but I don't really think it works. The fluids (oil, power steering fluid, etc.) light up green in the bottle without any UV dye in them, so that kind of defeats the purpose.

Would that nut being loose case an oil leak? I don't think it should, because the sprocket doesn't touch the seal. I guess if the loose sprocket bent the oil pump shaft and destroyed the seal/sealing surface it would leak.

The sprocket does touch the seal. Yes that can leak very badly.

Yeah, after some more research I figured out that the sprocket does touch the seal. I'll edit my original post to avoid confusion. Thanks!
