Oil leaks and other pests slowing me down

[budman k20]

Hi all,
I thought everyone could relate to my issues building my first truck and I figured it was about time to learn how to post pictures! So I included some build pictures of my 72 K20 frame off. I have been chasing an oil leak for some time now as the passenger side of my engine is coated in oil. The entire passenger side under hood area has oil all over it. There is a lot of oil on my intake also. I have replaced the valve covers I have new steel core reusable VC gaskets etc. and I still have oil dripping off the engine. Today I'm checking / shimming my dist. to ensure it is not the leak source. I checked the intake to block gap and that has a nice bead on that. I'm on my second set of valve covers and I am about to put on my third set as I'm trying a cast valve cover with cork gaskets now. I have put a bolt in the fuel pump rod hole and I'm going to remove my intake bolts one at a time and reseal both the threads and under the heads to eliminate all possible leak points. I will double check my oil pressure line and block fitting. What else am I missing? Once I get my oil leaks under control I get to tear my entire AC system out since a mouse got in my restored truck over the winter and chewed a hole in my glove box, SPID and made a nest in my blower squirrel gage. It also chewed up my brand new never used good AC ducts and some dash wiring as well. Man for such a small pest they can do a lot of damage when left alone! Anyway I just needed to vent....and find out if I can up load pictures!
