[DML] Re: Removing Exhaust Crossover Pipe

["content22207" <brobertson@xxxxxxxxxxxx>]

I wasn't advising a dual exhaust conversion (though it is advisable
IMHO) -- simply removing the crossover pipe to access not only the
slave cylinder, but also:
- heater core takeoff barb
- ported vacuum switch
- other water distribution pipe sensors
- heater core shutoff valve
- ignition distributor (raise up the fuel/air mixture unit)
- etc etc etc
The crossover pipe *CAN* be put back in the factory configuration
afterwards...

Studs holding the crossover pipe to the exhaust manifolds are 10mm --
much less likely to break than 7mm's holding manifolds to the block
(are steel on steel too). Mine came off with nothing more than
penetrating oil and MAPP gas in a plumber's torch (not acetylene).
Replaced the carbon nuts with stainless steel to ensure ease of future
removal.

You really should experience a PRV without that silly crossover pipe
in the way. Removes half the objections usually raised by DeLo owners.
"Hidden" items are suddenly accessible -- without touching the intake
manifold! (Fuel/air mixture unit may need to raise up however). 

Removing and installing the slave cylinder without the crossover pipe
in the way is one of the easiest procedures you'll ever perform on the
car. 100% guarantee it. I *DO* advise removing the heater core takeoff
line during the process.
