Ford F-150 Forum : “forgot to put oil in...”
forgot to put oil in...
so im doing an oil change today on my 2004 ford f150, and i got distracted at one point, and i ran the truck with no oil in the engine. i shut it off because i heard a somewhat loud knocking noise.
is there any damage done to my engine? i only ran it for maybe 30 seconds. i put oil in afterwards, but im afraid to start it again in case i bent a rod or something.
If it was for only 30 seconds you likely didn't do too much damage most the bearings will hold some oil on their surfaces, hopefully you just heard dry knocking and you shut it off fast.
Did you damage? Yes
Will it make any 'significant' change? Likely, and hopefully not.
If now that you've oiled it, and you start it and it keeps knocking...well then I'm sorry...
(Always make sure pressure goes up after an oil change.)
