turbo build/ mild restore

Ok its been a long time since I posted last, but life gets in the way. I've still been working on the scamp. Put in a cheetah reverse pattern valve body, and b&m ratchet shifter so no more on the column. Got the car aligned and took it out. Good news the turbo system works great only have it around 4ish psi right now just getting the kinks and bugs worked out before I turn it up more. Problem is I have a sizable oil leak looks like its coming from the top back of the engine. Figured it was intake gasket so I changed it out. Well it wasn't most of the oil appears to be around the distributor area, so I pulled it out to make sure the oring was still there and it was. Any ideas what to look for. Oh I also checked the oil sending unit there isnt much oil in that area so it doesnt appear to be the culprit. FYI the car pulls hard just on 4 psi cant wait to get it up to 8 and see what it does.
