[s-cars] Turbo oil H2O connections + maf delta

[qshipq at aol.com]

 I use a very thin layer of sealant on all oil and water gaskets, on new or reused gaskets...  As thin as you can spread the sealant is the rule.  WRT lock washers on a turbo connection Jeff, they aren't any better than (read: they become) flat washers repeatedly heat cycled by a red hot turbo.

Bill:

"I have a small but continuing oil leak at the top of the turbo (outlet)
connection. I have a new gasket to install, but IIRC it can still be
problematic and I
am contemplating using some hiTemp gasket sealer there.
Anyone have thoughts on how to make this a lasting, non leaking connection?
Fortunately (I think) the bottom connection is okay.

...   The surfaces need to be very flat.  and when they are, the small
gasket is sufficient.
On our aging turbos, that might be tough to ascertain. flatness, as I know
you like 'em with noticable boobs,
but I digress . I think the high temp sealer should do the trick.. obviously
don't goop shut the center hole.
I use lock washers on my connections in that area, because I want to enjoy
the next time my turbo turbine side grenades
and R&R it easily.

Enjoyin' Alison's V10 - S6 I hope!
