I have a '95 at about 300HP pulling a trailer for about a half hour at 1200 deg, then an 800 mile trip with tt. -floored for some Branson hills. . Got about 200 miles to a quart then. . It was at about 1200 to the quart up till these trips. At Branson, I noticed a little oil running out the fender and down the door. Got home and oil was getting embarrassing. . A few hundred miles later(empty) and oil just ran off everything underneath. . About 30 miles to the quart. . Noticed dipstick was pushed out so assumed blowby was bad. . Put a 1" plastic tube in oil filler hole, went about 18" and stuck the tube in a gallon jug so I could dump the oil back in. . Never got any oil in jug and the truck stayed clean. . But, oil cunsumption was still less than 100 mi per quart. Drove it about 2000 miles that way (check my old posts, I inquired to TDR also about this) while looking around for a different engine. One day I was headed into strong wind pulling a trailer on a hot day with a dirty radiator. Didn't want to boil radiator over as then I'm stopped. (different engine needed anyway) Temp gauge ran against the red and I watched for the steam in the mirror. Down to 45 MPH so pulled off to the side to get out of traffic and revved engine to about 2 grand. . Cooled down to normal, I took off and did the same thing a few miles down the road. . You got through that drivel, now the punch line--NO MORE OIL USE!! A few days later I gave my tube setup to a fellow CTD with a gobba blowby-my engines as dry as a bone... Incidently, when this was going on, I had a poor starter so it barely turned over. . all 6 seemed to have even compression, the engine ran perfectly, like yours. .
I could be off on the details a little, but it has now racked up another 18k or so almost all pulling a 33' travel trailer with oil consumption at about 1500 MPQt-some drips. . One thing odd, twice I ran empty at 85 MPH and it got about 20 miles to the quart with a huge mess underneath. . 70 MPH with the camper and nary a drop is spilled. . You surely thing I'm nuts or a blowhard--I've got lots of witnesses.
Incidently, when it was really going through the oil, I sampled the oil. The only noteable outawhack number was chrome, they suggested I had excesseve ring wear. .
Only thing I can figure out is that I scored the walls evenly, then running it hot at a little less throttle than when I messed it up somehow reseated (or daresay broke in) the rings again. .
I can give you more detailed info on my accidental fix--hey, a piece of cardboard and a half hour-what you got to lose?? You don't HAFTA tell anyone!!
