I have recently acquired a 1988 K3500 from a "local". Truck has records of a top-end rebuild that I haven't verified yet, but the transmission rebuild checked out, as did the re-gear so I am optomistic.
After changing the oil the truck seems to smoke more than before. I am using Rotella T4 15w40 and have been using a 50/50 mix (8ozs.) per fill up (20 gals.) of Power Service Diesel Kleen w/ cetane boost (grey bottle) and Supertech 2-cycle TC-W3.
The truck has been using 1 qt of oil every 600-800 miles depending on if the truck is loaded or not. I tried some Lucas oil conditioner (I thought valve guides) and it seems to have helped a lot.
After reading numerous threads I checked the pump timing (position) and came up with the pics below, I also checked for blowby and it seemed non existant. Injectors are an unknown, could be original with 142k on them. It was a military truck at the start of its life.

Will upload start up smoke vid when I get home.
I was wondering if the pump needs advancing, will that cause it to burn oil?
Thanks in advance for any help you can offer.
