Broken dip stick part II....un-cut!

climb under the hood before you remove anything. look at the back of the intake manifold under the distributor. intake leaks are MUCH more common than rear seals.
 
Your convertor cover is metal. Its structural, hence the struts to the engine mounts. They keep the bell hsg from breaking. So yea, take it off, wipe down what you can reach, drive it, check for leaks. Then put it back on.:D
Ooops, forgot; did you get the bottom tip of the dipstick?
 
More than likely it is your rear main seal. Valve covers like to leak and run down the back of the motor and sometimes look like a rear seal issue. But do what 1 ton said and pull the flywheel cover, clean it and run it again and that will tell you where your leak is coming from. Dont reinstall the cover until you are sure that the leak is not coming from the rear main seal. And by the way, my truck leaks oil, from everywhere and to be honest I dont worry much about it. I have never owned an older chevy that does not leak atleast a little bit. I abide by the drip theory, if it doesnt leak, its not running right.
 
Im surprised no one said a oil pressure switch, if electric, they like to leak at the halves when they get old, if i were you i would take a flashlight and mirror and look around a little harder, A valve cover leak or pressure switch is a lot easier than pulling the tranny only to find out it wasnt a rear main leak.. Also, if you have the intake on with the little cork or rubber gaskets on the ends of the block, throw em in the trash and use "Right Stuff" black rtv, it sets up quick and will seal better than the supplied gaskets in the kit... I had a valve cover leak on my nova once and thought it was the back of the intake when in fact we found out the valve cover gasket wasnt sealing right... Nate

pressure guages are notoriously wrong, as with all of the guages in our trucks. that pressure sounds kind of low to me, but you're probably fine. i think 60 psi is average - can someone verify that for me?

I read in a mag a while back that a basic chevy motor should have 30-40 PSI at idle and gain about 10 PSI per 1000 RPM up to about 60-70 PSI.

Seems to be about what all my GM motors did so sounds good.
 
10 psi per 1000 RPMs is all you need. 99% of them do better than that, but it is all that is required.
 
Oil moves down and back. On boats we use water soluble markers to locate leaks. You make a mark somewhere, and if the mark is gone or partially missing, you can see where the water has been. It will help you trace the leak if try something similar. I hate oil leaks cause they attract dirt.
 
Could be intake leak, rear valve cover leak, or distributor gasket leak. Check all those, if you haven't already.
 
finally! someone else with some sense. dont turn a wrench on anything, until you've eliminated ALL other possibilities. work smart, not hard.
 
Thanks for the suggestions guys, as you all can tell I've been away from CK5 for over 3 days working at the church on VBS. I finally got a break tonight and came home to get some rest, man @ almost 11:00!

Does this mean that nobody else has any common sense?
