I did think of that!!!!!Runit wrote:I know of an old Ferrari race V12 that developed water leaks around some of the inlet guides. Every attempt to fix the leaks with oversize guides had short lived success or was an outright failure. The owner's mechanic's "it's off to a new owner" solution was to connect the engine to the cooling system of a street car (using the heater hoses) and circulate coolant and stop leak through it for a couple of hours.
...but since its staying with me for a while it's probably best I didn't think of that
The first was an easy fix, the second is still leaking after grind/weld so either I didn't have the right spot or the crack is growing. The guides are currently 9/16 which is 2mm oversize.....so I guess worst case I pop a 5/8 or 3/4 hole in and weld around top and bottom and re-drill for a stock size guide...and then make all new guides becasue these are custom with a 5mm stem instead of stock 7mm. Thinking about it just doing them all might be the fastest, easiest, most reliable way to proceed.......I'll spend a couple more hours chasing leaks before using the nuclear option I guess.
