[Healeys] Main Seal Leak Eimination Alternative

[Ray Carbone]

Recently, a member of the Positive Earth Drivers Club was doing research on
how to stop the common rear main leak that occurs in most LBCs. This topic has
been discussed before and those who have not installed a rear seal had the
option of reducing positive crankcase pressure through the installation of a
PCV valve.



It seems that, for years, drag racers and dry-sump engines have incorporated
the Bernoulli Effect to suck gases out of the block and into the exhaust
system.  Implementation was usually through a hose connected to the valve
cover, passing through a check valve, and entering the exhaust through a
bevel-cut piece of pipe welded into the exhaust system. The system parts are
relatively cheap with the exhaust weld the only real task. The only
requirement seems to be the presence of minimal backpressure in the exhaust
system.




Has anyone done this on a Healey?  If so, what was the result?



Thanks and all the best,
