I am going to have to check i.a.c. to make sure.Thought had 12v.+ 5 but better double check.I don't have one of those weird light deals,I'm a carpenter not a tech, Scotty. Any way appreciate all help!

 

A cheap test light is all ya need.

 

Used test light + multimeter before thought it all checked out. thanks

 

Are you getting power on two wires??

 

If by "block blowby" you're testing the piston rings, then that has nothing to do with a leaking plenum gasket.

Here is a picture of the plenum plate on the bottom of the intake.

 

May have used wrong term! There was a videos on YouTube how to check.By plugging or pvc chk. Can't remember exactly how but that's bout it.creates a suction at Valve cover or something.Its been a few wks.Memory ain't what it used to be! I believe if plenum gasket leaking it effects your vacume then your idle!

 

With PCV disabled, you should have a little bit of pressure in the crank case. If you still have vacuum, that's a sure sign the plenum is blown.

 

Thanks going to 2d check that to!

 

Right, you disconnect the vacuum hose from the PCV valve, plug the hose and plug the valve. Pullout the dipstick and connect a vacuum gauge to the dipstick tube. Run the engine and the piston ring blowby will build some pressure, but if a vacuum is drawn then the plenum is leaking. This test will not work if you have leaks in the crankcase system anywhere, such as a leaking valve cover gasket, or the grommet the PCV valve sits in, etc..

 

What is the whining you refered to? I have had an alternator whine for a long time but I thought it was caused from diode's going bad.
