is coming out of the Square again, but this time there is no stock engine to
put back in!<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=3 face=Calibri><span style='font-size:12.0pt'>The
first build failed because the AA cylinder set was defective, the galley plugs
were done wrong and I removed the windage tray, which maybe you don’t
need in a bus<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=3 face=Calibri><span style='font-size:12.0pt'>As
if your going around a corner that fast your Bus will be on its side, but in
our application you need the tray AND a Tuna can sump to keep from oil
starvation.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=3 face=Calibri><span style='font-size:12.0pt'>The
second build failed when the lifters showed wear from not rotating, amongst a
couple smaller problems. The third build re-used the same AA cylinders
and KB pistons<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=3 face=Calibri><span style='font-size:12.0pt'>From
build 2 which were noisy when cold but fine when hot but some may remember that
when I started it with the break in oil, which I used because it had a new cam
and lifters in it (same<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=3 face=Calibri><span style='font-size:12.0pt'>Cylinder/piston
set, I never even pulled the pistons from the jugs) the engine got so tight
when at temperature that it almost wouldn’t crank over (it was NOT
overheated).<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face=Calibri><span style='font-size:12.0pt'>So
since new the 3<sup>rd</sup> build, which now has 10Kmi on it has sounded like
a diesel once warmed for a few minutes, clatters like mad below 2000RPM, above
that… fine, when started cold, fine… unlike build 2 which was noisy
cold and quiet hot… now one of the pistons clangs away pretty bad in
there till fully warmed so its time to do something before something bad
happens.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=3 face=Calibri><span style='font-size:12.0pt'>Since
it’s the same piston/cyl set from build 2 it must be that the break in
oil damaged them, it was only in there for 40 miles but this kid at 1000miles
on it already, so they were basically broken in… and ONE person on
the forum suggested that this was an issue with break in oils. Anyone
else heard of this? Once the oil was changed everything was free moving
when hot.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=3 face=Calibri><span style='font-size:12.0pt'>Gee…
this harkens back to the Amzoil days when that ruined my engine back in the
80’s!<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face=Calibri><span style='font-size:12.0pt'>After
talking with the Kit designer Jake Raby, Im going to bore out the original 2L
94mm jugs to 96 and use those with new KB pistons, and have the shop fit them
carefully, last round I just put the pistons in the Jugs, set the rings and was
done with it but the Stubby little offsetless KB’s are VERY sensitive to
clearance and Jake hates the quality of the AA’s cast as well as the poor
quality control of their boring so they are probably the issue here. The
good news is that the lower end is perfect, excellent oil pressure and no
starvation, still a bit worried about the valve lifters as nobody could figure
out why the last set didn’t rotate but the adjustment has held fine in
the past 10Kmi so they are probably OK.<o:p></o:p></span></font></p>

same again!<o:p></o:p></span></font></p>
