Re: [T3] Oil Pressure Relief Valve Spring Length

<x-charset iso-8859-1>Hmmm... interesting!  Gene berg always blamed low oil pressure on old cases
but I dont think he ever actually layed a finger on the lifter bores.  You
do need to watch out for all those crappy quality lifters out there but I
have 164K on the case in the square and the oil pressure is great for
bearings that have 77K on them.
