318 - High Oil Pressure

74Dart318 said

Thanks everyone for the help! Much appreciated. Didn't know people suggested against synthetic for a certain number of miles.

Well, should have the pan off tonight and will work on cleaning everything up, removing the old pump, and installing a new one. Probably take my time and not have it put together for a few days. No need to rush.

Hope I get the gasket to seal again!

If the bores were prepped correctly, you can switch to synthetic as soon as the cam is broke in. If it takes X amount of miles to seat the rings, the bores weren't prepped correctly.

I left my break in oil in until I had 500 miles on it because it had a big zinc package and a bunch of detergent in it. Then I switched to synthetic. If the lobes on my cam weren't so aggressive, I'd have broke in the cam and the switched it over to synthetic.
