On the 2nd oil cooler, heading to 3rd

Chas, lines in/out of cooler are both -12. The 'large' line in pic is also -12 scavenge from pan to pump. Just camera position that has made it appear larger. NZ-oregon- is a timber/tree type out here, probably got a fancy botanical type name that I cannot remember at moment

To save you the stress I could draw up a set of plans if you want to fabricate your own-- need a lathe,mill,drill press etc.

This may be a dumb question but why are you worried about an oil cooler installing a thermostat to bring the oil temp up?

Intially when I built my cobra, I really liked the look of the oil cooler in the front. At the time I didn't want to just put a "dummy" on so I went ahead and ran all the lines. -10 at the time, then sheared a distributor gear and the engine builder recommended switching to -12. So I did all that and realized my engine was not getting up to temp like I wanted to see. Sooo, I put in a oil thermostat to bypass the oil cooler unless oil temp got greater than 215 degrees F. Seemed to do the trick. Looking back, it was a ton of time, money, and frustration to have the "look". If I'd do it again, it would be a dummy. So now I'll added some rubber spacer for vibration and rods to tie the top and bottom together and call it a day. Hopefully!!!

what temp was it getting up to?

70 degrees Cel. I wanted to see it between 90 - 110. Thats what I understand as a good range. I got a big chunk of cash in the motor (from my standards) and I want to make sure I take good care of it.

There has been a lot of opinions on here as to how warm the oil needs to get to burn off the condensation. From my research I am pretty comfortable with the 65 degree cel number, that brings it to 155 F. Anything over 75 cel is fine, Mine gets to 80 cel max, it does not need to be over 100, nor does your oil psi need to be over 60 lb's, You might want to try taping off the back of the oil cooler, Other people have gone the low tech route by sealing off the lines to the oil cooler with cardboard and have have great success.
