If you recently adjujsted the valves, the possibility exists that you didn't torque down a retainer nut tight enough.

Pull the valve cover, and make certain the number one cylinder valve retaining nuts are tight.


You have a few extra injectors laying around. Take out the #1 injector and replace it with another. If the problem persists, Go back to the boneyard and get a few of the injector fuel lines.

Take the new lines and bend them so that the injector will spray into the air. Now BE CAREFUL because you should get a high pressure mist from the nozzle. Comnpare a 'good' cylinder with the one in question. Are they spraying roughly the same amount, is the mist pattern the same?

If the mist pattern is the same for all the cylinders, you can rule out the IP for now.

For about 50-60 bucks, you can pickup a cheap diesel compression tester on eBay. Mine works fine, but the cheap plastic gauge cover cracked, so now I can't throw it into the tool box.
