Sorry I haven't updated you sooner. I did finally get around to dropping the
oil, hooking up the
oil cooler lines, and taking her for a spin. Guess what happened....most people thought the
oil pressure would have dropped a bit further by adding the cooler. Well, I'll keep you in suspense a bit longer as I explain another bit of info. When I brought the engine to the dyno for the initial cam break-in, I sent it down there with a NAPA gold (ie WIX) filter. After the break i they changed the oil and put on a Fram, which I left on there until the first oil change at about 500 miles or so. I figured the Wix filter would give me a few extra PSI and was hoping it might offset any loss I was expecting from the hooking up the cooler. Just to remind you my cold start oil pressure at idle was 55 psi. After hooking up the oil cooler, and putting a NAPA gold (WIX) filter on I started her up. Guess what the gauge read? 70 psi! Thank you Santa for the Wix filter! I'm still shocked that it made that much difference. After letting her warm up I would normally see an average cruise oil pressure of about 40 psi. I was seeing an average of 55 psi after the filter change and adding the cooler.
