Subject: Re: Sandwich oil cooler adapter question
Content-Type: text/plain; charset=us-ascii
I had about the same thoughts as I proceeded to install the EMPI adapter.
My thought:" When the hell are these two valves ever going to fall into
sync?"
Is the 5/8: freeze plug you mention the cup type or shallow dome"
Is there any danger of the installation process breaking the oil filter
mount when it is installed with a hammer blow?
I was a little concerned when I got no instruction with the Empi adapter.
Thanks
