Oil consumption

I've been using ALOT of oil in my '78 F250 with a 400\4 spd, probably about a quart every 250 miles but the underside of the truck is dry so it's not leaking. I have seen some smoke out of the driver side tailpipe on startup but not every time. Engine runs strong and was rebuilt by a reputable shop about 10-12 yrs ago by the previous owner. Truck has only been driven maybe 10,000 miles in the last 6yrs. What am I looking at, replacing the valve seals\guides? It did have a broken valve spring repaired about 4 yrs ago. Should I have the heads completely gone thru now? This seems like a tremendous amount of oil loss for bad valve seals.

Have you checked the spark plugs? Do any of them have black soot or carbon on them?

Smoke on startup is usually bad valve seals...

I'll check the plugs tonight. I've also smelled gas at the exhaust pipe.

I wouldn't sweat it, my 351m burns 2 gallons per 1000 miles no smoke, no leaks, and it doesn't make any rattle's etc.... It just likes the oil I guess, lol, as long as it keeps running as good as it is I'm not going to worry about it.
