<VV>: Fan bearing baffled no more & leakdown test.

[Bryan Blackwell]

I've finished making a leakdown tester using a couple of regular 
gauges, so my process would be a little different.  The idea is to get 
100 psi of pressure on the supply side, then whatever you have on the 
engine side is the percentage.

Now, a cold Corvair engine may well have some cylinder warping, so I'm 
not sure how good the test will be.  It should show up anything really 
major - I'm going to use it (for the first time) to check out the 110 
that smokes heavily.  Ideally you'd do the test on a warm engine.
