this can't be rite???????
I have my days when I don't want to work on anything but today was not one of those. I replaced my (growling) turn signal relay, adjusted my headlights, pulled my IC pipes out and removed the foil and cleaned them up. Gave them a fresh coat of paint. When I put them back in I figured this was a good time to rest for leaks. I rigged up a air line. I set my regulator on 20psi. While flowing its closer to 12psi. I had a few leaks so I tightened the clamps. I could hear air blowing but had no leaks at any of the boots. I started feeling around for the air. I squirted some soapy water down by the front of the pass head. I could hear bubbling. So I moved the hoses. The air was coming out between the head and valve cover. I'm no expert by any means. I know very little about diesel motors. But this doesn't sound rite.

I guess you could check the stem seals by pulling the VC and lookin' around. Maybe squirt a little oil on the stems and try to hear 'em sputter?

I figured I would get some advice first. Need to know what to look for. Is it gonna look the same as a gas motor??

This is what you'll find under the valve cover. The injectors are the brown squarish thingys in the middle of the rockers.

Ok. Thanks for the pic. Its kinda hard to see on my phone. If they get my internet fixed I can look at it on the computer. Am I looking for air coming by a valve? Or the injectors maybe?

Before you pull the valve cover, pull the central intake y-pipe that goes between the cylinder heads and pressurize the intake plenum right there to confirm your suspicions.
Loosen three clamps and it's out of there.
It might save you a bit of diagnosic work.
I just want to make sure that you are not being fooled by air coming out somewhere else and it's fooling you.
