    For those of you who remember I posted a while back about bad
    oil pressure.  Well after 3 weekends and $100 I now have 60 lbs
    at speed and 25 lbs at idle, up from 25 and 5.  Also I now have
    to replace the exhaust system, fix the radiator, adjust the carbs,
    and fiddle with the timing.  This leads to various questions and
    comments.
       I found out that it is possible to replace the main bearings 
    without removing the crankshaft, after removing the main bearing
    caps there is enough clearance to slip the bearings around the
    shaft pushing the old upper bearing out, after which you reverse
    the procedure to get the correct bearing on the top instead of the 
    bottom bearing which you used to push out the old top bearing.  
       About the radiator, don't use on overly stiff hose for the top
    radiator connection.  It will eventually fatigue the tube coming
    out of the radiator into leaking.  This will cause radiator fluid
    to spray back onto your carbs which will make your car run bad and
    smell worse.
       The carbs, painfully I have come to the conclusion that I may 
    just have to rebuild them.  I figure that if the radiator fluid
    causes them to misbehave they are probably have vacuam leaks around
    the shafts.
       A question about adjusting the timing.  Is it possible to adjust
    your timing by rotating the distributer until the car sounds best?
       Oh and the exhaust, when I was taking the exhaust system off prior
    to removing the engine the resonator gave out.  While this made removing
    the forward part of the exhaust system easier, it also makes the car
    very noisy.
       Another question, is it possible to disconnect the drive shaft from
    the transmission without also removing it from the differential?  I
    have really begun to detest having to alternatly raise each end of the 
    car to get the drive shaft disconnected so I can remove the engine.

    Awhile back there was alot of mail about why we had/kept LBCx which
    seemed to cause us mostly large bills and dirty faces( you never
    touch your face but it always comes out looking like you used it to
    rub the grease off of some part).  This weekend I got my new Crown
    Victoria catalog.  It has all these nice sub-assemblies available
    for my car( 74.5 MGBGT ).  I went out behind the chicken coop and looked
    at the remains of my orginal car and was thinking about how I could
    still fix it up.  Just a new front sub-assembly, sills, floor boards,
    rear quarter panel, and a little inside work.  I could move the 
    engine back in from the other car and the interior.  Or mabye a new
    interior.  I think my uncle is going to get upset and does anybody know
    an easy way to remove spot welds?
