Missing glow plugs
Bought a ****-box project truck; 2008 F350 SD, 4x4, 6.4 deleted and studded. When I bought it the seller showed it had a code for #3 glow plug, no big deal. When I went to replace it I found 2 glow plugs missing.....just the holes with the harness in place. Truck runs great, very strong, with no blow-by. The seller was a real sketchy type, lied about a bunch of stuff, so my first instinct is he did it to hide a defect but I can't imagine what that would be. Any one care to speculate on why someone would leave them out? I've installed new plugs but haven't started it yet, in the middle of replacing a ton of parts.
Thanks

I was able to install new ones so we'll see if they blow out again, thanks for the tip

No blow by entering the crank case, if there was compression escaping through the open holes it wasn't enough to blow out the connectors. No, the plugs were missing. Wierd i know.

Having driven a 6.0 that wasn't firing on all cylinders when it was too cold, you would hear/feel a couple dead cylinders - and with no compression because of no glow plugs, you'd have had a couple dead cylinders. Unless you didn't drive it/start it before purchasing it? In which case if you put the new plugs in before trying to start it, you'd never see the dead cylinders.
Sequence of events here has me a bit stymied, because what amounts to a hole in a couple cylinders should DEFINITELY have run rough, been pretty loud, and flooded your oil with unburnt diesel - not good for your bearings.

I definitely drove it first and for a couple weeks after before starting to work on it, ran and starts fine, no misses or noise which i also find odd. Haven't started it since installing the new GPs yet, still putting the front end back together, but should be trying it in a week maybe.
