1)LBC Engine Trouble:

My friend rebuilt the engine in his 1974 MGB this summer, and he is having a 
problem with excessive oil consumption at sustained engine speeds above 3000 
The engine seems to run well; it makes good power and all cylinders fire evenly.
All of the original emission control equipment was removed by a previous owner--
could the missing PCV / Gulp valve be causing some problems?

2)LJC Engine Trouble:

I have a 1986 Mazda RX-7 exquiped with the normally aspirated 13b rotary engine
which I have owned since 1989.  This car has about 107,000 km on it and has been
serviced regularly.  While driving at about 60 km/h it developed a miss.  I 
it into the local dealership and they at first thought that the problem was a 
igniter coil (no spark).  They then told me I had lost all compression in the 
rotor, possibly due to a bad apex seal.  Is this sort of sudden failure common? 
The engine had  good compression in both rotors when it was serviced this
