So it’s my dads truck but it’s a 1994.5 f350 crew cab dually custom service bed 4x4 7.3. We just put new injectors, valve cover gaskets, plugs for the valve cover gaskets, and glow plugs in it last night. It’s idling kinda weird but has a lot of power and burns just a tiny bit of oil. What could it be

 

What brand of valve cover gaskets did you go with?

The rough or weird idle could simply be air in the hpop system. Driving it will clear that up. It might take a bit.

Did it Burn oil before? There could be a chance a o ring got nicked on one of the injectors. Does the oil level go down o. The dipstick or is it just smoking out the rail pipe that make you believe it burning oil?
