I just checked my engine and sure enough, both holes close to the fuel pump are open, no bolts at all. Weird that it never leaked before. I guess the thicker oil kept it from leaking out. What is the other hole for anyway? Should I just put a bolt in both spots??

The bolt holes were originally for front motor mounts. PLug them both with short bolts with a little sealer on them.
Apoligies for me and 10 yearguy for jackin' the thread.

But the link you sent was for a breather. I already have a breather on pass side. What did you suggest for drivers side?
The link for the breather, the breather has a hole in the top that you put a grommet and a pcv in and hook the pcv to a manifold vacuum source. Usually on your carb. That style of breather acts like a baffle to keep the pcv from pulling oil thru it. THat type of breather doesn't have vent holes on the underside. It's only open down thru the centre. They look the same until you flip them over. If you don't have a baffle of some kind you'll pull oil thru and not vapours.
The theory behind a pcv is the pcv uses manifold vacuum to pull the vapours from the engine. You need an inlet source(breather) for air to be let in to mix with the fumes. If you have no inlet air source the pcv won't work.

Never in a million years would I have thought to check that bolt hole! At least it is an easy fix though.

A lot of times that bolt hole isn't drilled quite all the way thru and there's just a thin piece of casting in there which eventually falls out.
I learned all about proper pcv's and leakage points on a motor by trying to run some aluminum valve covers that had no holes in them for a pcv or oil filler too!
Almost lunched a motor. Got to enjoy being towed home 90 miles behind my dad's 440 chrysler in -20F weather.

Got it. Now that makes sense as I thought that breather was open underneath.

Good deal!

Added a simple breather and a PCV breather on the other side with a 3/8 hose straight to the back vacuum port on carb and ran it hard... No more leaks!

Thanks all who had input!
