*Q--Michael I would be interested to know why you are thinking that a
rebuild is necessary at this stage. The drop in oil pressure alone would
IMHO not be reason enough. Is the engine making odd noises or burning
excessive amounts of oil? Perhaps a "ring and bearing" job would be the
best way to go.*

*A--There are no odd noises and oil consumption isn't bad, though it is
more than when the engine was fresh.  I have not done a recent compression
check either static or dynamic but as said oil pressure has dropped
considerably from when the engine was fresh perhap 15-20 psi across the
board with hot idle pressure of 10-15 psi.  I did replace the oil pump last
year which resulted in perhaps a 5 psi increase in pressure and as a
further experiment I also replaced the bearing shells that were accessible
by dropping the sump (lower shells to cylinders 3 and 4) but neither of the
last two resulted in a substantial increase in pressure.  Naturally if the
teardown shows a lot of wear in rings and bores I'd be happy to keep things
to that. *

Q2--My car has an early aftermarket valve cover and looks like the ones
sold by Ray Juncal minus one fin and with a flat versus a slightly convex
top surface.  There is no vent nipple and it has a spring-loaded filler cap
that probably does not make a tight seal though there is no oil blow-by.
Is there a real advantage to installing a PCV valve and if so where should
the hose terminate?  I removed the original LeMans kit CAB some time back
and would prefer not to refit it.
*The PCV system that I've developed doesn't involve the rocker cover at all
and, by the sounds of it, your engine would be an ideal candidate. Check
the web site that I showed  ... the system is virtually invisible but does
require the replacement of the manifold balance pipe.*

*A--Can you please give me the website address?*
