Hello all,

 

In April I asked some questions about this issue of &nb= sp;managing the cooling flow for #2 cylinder and there was a prolific and en= lightening response that helped a lot.  The most common piece of advice= was to build what was termed a =E2=80=9Chat box=E2=80=9D in the forward wal= l of the oil cooler box to allow more air around the back and bottom of this= cylinder.

 

Someone posted a photo of that fix and it was excellent.&nbs= p; Now I=E2=80=99m ready to go to work on this project and I=E2=80=99ve sear= ched my data bases in different computers for that photo for a couple of hou= rs to no avail.  I=E2=80=99m hoping that whoever was kind enough to pos= t that picture will resend.

 =

Thanks in advance.
