If you just wait a week (I hope), you will all find out, in the case of my
vanagon, who is right--at least in the short term means. It was my vanagon
which stirred up this recent inquisition of oil pres woes. The engine is
coming out tomorrow, the parts, HOPEFULLY arrive on tues. And all will be
done by the end of the week. Here's what I'm doing: New heads, Boston Bob
"rebuilt" rods, new rod bearings, new piston rings for good measure, new
oil pump, and the other basics. Boston Bob so much feels this is the root
of the matter--the rods, that is--- that he paid for the rods and bearings.
Of course, Mr. Lilley, if you would sponsor me a new crank and main
bearings, I'll gladly rally for your theories.
Actually, it will probably be two weeks, since I'm mailing my old rods and
bearings back to Boston Bob for analysis, and subsequent publishing of
results. Anyone in seattle area wanting in on the sponsorship, I need a
digital camera for list follow-ups (USB preferred.) Also, a nice kerosene or
electric heater would be nice. Sponsorship contracts could be donated by
one of those many list lawyers that are always yapping about sueing another
list member.
let me know.
Donations accepted.

Bob,
I might not have the years of experience you have at rebuilding WBX engines,
But on the few that I have taken apart, I have seen the center main bearing
saddle case fretting like the T1 engines. On another engine I saw rod
bearing wear consistent with my thinking that the increased stroke is the
real problem not so much the bolts. The rod bearing was worn at an angle
(one side more than the other) and it was consistent with the location of
the
rod on the crank. The bearing was worn and you saw the copper colored metal
under the top layer of the bearing in the shape of a triangle.
Can you explain just how the rod bolts stretch over thousands of miles,
allowing the cap to bend and but the nuts do not back off? Like I said, I
can see the nuts coming off the rods
From my experience the slightest reduction in torque will allow harmonic
vibrations to cause fasteners to back off in high stress environments: nuts
on the rocker arm stand, valve adjusting screw nuts, nuts on rods, case
bolts, etc.
The WBX engine is based on a T1 engine and suffers from some of the same
problems.
