351W Coolant leak
My 408, which is based upon a late model 351W roller block seems to have a very small water leak at the intersection of the timing cover, engine block and oil pan as I've noticed moisture there.
I can't seem to pinpoint the leak exactly though and at first thought I had a seeping freeze plug. When I bring the car in and park it after running hard I'll get a teaspoon size drip running down the right front corner of my oil pan.
The problem is I can't seem to pinpoint the leak location exactly because the seepage seems to get blown around the lower right front of the engine. I tried pressure testing the cooling system and it would hold about 20 pounds for 30 minutes and no obvious leaking!
Any ideas?
