Thanks for the download, Paul.

    Well, since I already have the scavenger pump I can always put it on.
But, think I'll make a couple of more tries for a better sealing seal.

    Yes, I am equally eagered to get some halfway vaild flight data with the
new manifold.  I may have mentioned that after the incendent involving the
engine surging, I reset the injection time for a mite bit richer.  In fact,
I joked that I was probably trail twin black smoke trails like an F-4
Phantom jet the next time I took off after the surging incident.

    Well, back on the ground after the oil leak, I ran up the engine while
decreasing the injector timing and was getting rpm indications of 5300 rpm
and perhaps a bit more.  Now at 5000 rpm and above during ground run up the
aircraft is really bouncing on its gear, which could possible effect the rpm
needle.  I have a data capture mode on the HALTECH that also captures rpm
readings, so after I get the oil leak dealt with, I'll try a runup with the
data capture mode on and see what rpm readings I get with it.  Less likey to
be affected by the bounce or optimistic eyeball{:>).

   I do recall early on that Tracy was supposedly getting around 4800 rpm
and I was getting 5000 (I've checked the tach with a prop tach) and yet even
then his aircraft performance was much better.  I believe my aircraft ways a
good 150+ pounds heaver than Tracy's, empty the aircraft weights 1170 lbs,
I suspect Tracy's is considerably lighter with an RV-4 probably coming in
around 1000 lbs slightly less or more Which would probably  account more for
climb difference that top speed.

    I suspect that one of the reason that my oil leak may have started, is I
believe I am producing considerably more power (based on the ROC after take
off) and possible getting more blowby gases in the crankcase which could be
pressuring the gear box.  Charlies Harbert has suggested venting the gear
box so it cannot pressurize which I may do.  However, I do have three vents
to the crankcase so I sort of put that potential cause down the list.

    In anycase, will keep you informed.
