Plain Jane OEM nothing to see here rebuild

Reporting back:

Got a dual belt pulley on over the weekend and took the car for a drive tonight. Obviously it's much cooler tonight than it was Memorial weekend (100°). It took much much longer to heat up and was cooling down with the efan blowing at lights. BUT temps did get up to just below 220°.

Oil temps seemed about normal at 200° and pressure seemed normal at between like 30psi and 60psi.

I've checked my radiator hoses they aren't collapsing.
I did what I could to test for cold spots on the radiator but did not have time to take the undertray off and feel the front of the radiator. I simply stuck my hand between fan blades and felt with my fingers...all the spots I could check seemed the same temp.
The top passenger corner of the fan shroud does not sit snuggly at all. I can pull it off the radiator by about 1/3 of an inch. I'll resecure that, but I wouldn't think it would have that much of an effect.
I'll go through and put some foam around oil cooler, condensor and radiator...just to make sure.

One thing I'm curious about is my oil cooler. It seems like I have a pinhole somewhere in the oil cooler. I keep finding oil pooling up on the bottom of the radiator and in other strange places around the oil cooler. I had a failure on one of my oil cooler hoses on one of my first drives after rebuild. It created a fountain of oil. I had thought that oil on the bottom of the radiator was simply gravity from me not being able to get the oil cleaned up off of everything (ie: fan blades, fan shroud, etc). Reason I bring this up is I'm curious if I do have a pinhole and I am loosing hot oil..and it happens to be on the radiator fins...seems like that could cause the radiator to not cool as well. Any opinions on this would be greatly appreciated.

I had a similar problem with oil on the bottom of the radiator. It turned out to be that the crush washers weren't sealing. It only showed up when the oil pressure came up. The washers are supposed to be replaced any time you crack the hose loose.

Thanks for the heads up. I did not replace them when I replaced the leaking hose. I don't remember if I replaced them when I did my rebuild. New ones sounds like a good starting point.

You'll also want to be careful not to overtighten those banjo bolts on the cooler. If you do, the result is often a hairline crack in the oil cooler where the theaded hole is machined, which causes a leak.
