Right. So... Today I pulled the driver's valve cover off. Found that I need new CCV O-rings. Looks like when the CVV O-rings extruded far enough past the CVV filter piece, it left a gap for unfiltered air to get in... which is why my turbo compressor looks a bit sandblasted and worn down on the edges... I thought it might be the K&N filter, but I didn't see any real dust inside that part of the intake. Past where the CCV tee's in, though... lots of oily dust on the inside of the tubes. Also found one injector(or just the solenoid) had been replaced at some time. Pulled #2 glow plug. Looked and tested fine(I just tested like a IDI plug though - if the tip glows quickly it's good). Then checked the next three with a wire... all seemingly OK. Checked the UVCH - looks to be good? I mean, I plugged a new GP into each wire in turn(glow plug in my hand with ground wire), and it got hot when the key was cycled. So, I did the 50C mod on that UVCH. We shall see if there's any difference tomorrow. ...I probably should have just swapped out with the new set of Motorcraft GPs I have and used the old ones for spares, but I didn't... I might just try a spare/new GP relay, see if that makes a difference. Still need to pull the passenger's side cover off.
