Doug:

Use new seals under the injectors when replacing them, too.

Bad injectors usually send out a solid stream of fuel rather than a nice atomized cone of mist, causing hard starts, rough running (the angle at which the stream exits the nozzle varies, so sometimes it ignites well, sometimes not), etc. You are probably due.

A quart in 2000 miles more or less eliminates low compression due to bad rings -- if the rings are bad enough to lower compression significantly, you generally have considerable blowby and excessive oil consumption. That leaves the valves.

For sure do another adjustment. I was stunned that the exhaust had closed up that much -- that little clearance cold means it never closed hot. I get much better performance now!

What makes you think you need a new injection pump on the Ford? I wasn't aware that the PowerStroke HAD an injection pump! I thought it had unit injectors (in the head, operated by the camshaft, electronically controlled).
