<VV> Re: Here we go again (Total Seal)

[Crawford Rose]

I have used the cast iron Total Seal in a normally aspirated and a turbo 
application with no problems.  I have had problems with TRW moly rings not 
seating, which is why I went with cast iron when I bought the Total Seal. By 
the way, GM used this same type of gapless second ring "total seal" set up 
in the 1960 replacement piston ring sets so I don't think one can 
categorically say they are not approved for use in Corvairs.

I recommend that the fellow with the leaking turbo carbon seal replace the 
seal where he has seen that he has oil in his intake. It doesn't make sense 
that the increased engine vacuum is causing the problem and I would 
certainly not change the engine's piston rings because the turbo is leaking 
oil!  Also, you may be permitting gasoline to wash into your turbo bearing 
by continuing to run the turbo with a bad carbon seal.

To the fellow who wants to temporarily disconnect the oil line while the 
turbo is running, I have some good impeller shafts and a new turbo bearing 
to sell to you if you do that and find that your turbo seizes at only 10,000 
rpm...
