landtortise89 is starting off with a positive reputation.
I have an 89 with a 7.5 with a similar problem but mine seems more excessive it has used enough oil in the last 100 miles that the lifters were noisy on my way to work this morning (no place to get oil at 7 am) I am not sure exactly how much oil it has used but id guess 3-4 qts no smoke and a very minor valve cover leak on the left bank, nothing else as previously described. It doesn't have a cat either. Truck sat for 3 years I revived it runs great changed the plugs 7 of the 8 were good and clean white in fact the number 8 plug was badly fouled from a non functioning plug wire it was missing badly when this was happening and is not now. I am stumped. truck shows 67k miles which seems very much to be original based on the condition of the truck.
