Tonight while driving around town I noticed the temp gauge was the hottest it's ever been, at around 170-180 degrees. Prior to tonight it's never been past 160 degrees. So I finally get home and open up the hood to see if I have a coolant leak or anything. While looking around I noticed I'm getting oil seeping from between the driver side head and block. Not much, and I can't find much else, but I've never found this before. It still seems to run fine. No bad sounds, oil pressure is good at around 80 psi. Anyways, I've been getting on her pretty hard lately with the but not enough that I would've thought I'd harm it. So, is this oil seeping between the head/block normal, or do I have bigger issues waiting to turn up? Thanks.

I would rather see 180/180 temps than 160 temps. Your engine will be running more effiecently.
160 is TOO LOW an you cause much more wear at 160 because the components havent expanded to their correct dimensions- lots more slop at 160 than 180.

One of my shop manuals had a graph showing cylinder bore wear versus temp, and I remember even at 160 there was still a fair amount more wear occuring than at 180. You just want to be at operating temp, not under.

I'll add if you used oil on the head bolts to ge tthe right torque, you may have just used a little excess. It takes a while to work itself out. I wouldnt sweat it.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

Well, I bought the motor from an original 60,000 miles 68 Newport. We did nothing to it other than replacing the freeze plugs, oil pan/sump, and timing chain. No leakage then. Also added a 4 bbl setup. Other than that, it was never apart.
