bought a 54 about one and a half year ago. ran good when i bought it but had not driven it more than 10-20 miles before doing a lot of work on it. Brakes, steering, cleaning under the hood etc. got it ready for a good drive test. Drove it about 150 miles and it used 4 qts of oil. Had lots of suggestions from friends, but wanted to go to the experts befor e trying anything or rebuilding the engine. any suggestions would be appreciated.
Thanks
Frank

That is a quart of oil every 37.5 miles. That is a lot of oil. With that kind of use, you should look like a crop duster driving around. Do you? Is it burning or leaking? If burning, are you sure its not leaking on say the exhaust manifold and burning off as opposed to burning as part of the combustion process?

Do a crankcase flush by adding 2-3 quarts of Diesel fuel or kerosene to a fresh change of oil. I'd suggest using straight 30 weight detergent oil, not some kind of fancy multi-weight stuff. Run the engine at a fast idle, maybe 1000-1500 RPM for about 30 minutes.

DO NOT DRIVE THE TRUCK OR PUT ANY LOAD ON THE ENGINE DURING THE FLUSH!

Drain the oil/Diesel mix immediately after shutting the engine down, while it's still hot. Any sludge or other crud that's built up over the years will drain out with the oil. By overfilling the crankcase enough to make the crankshaft and connecting rods dip down into the liquid, it splashes the thinned-out oil around like the agitator in a washing machine, doing a better job of cleaning than you could possibly do with a brush and solvent. In the process, it should dislodge any carbon under the piston rings that might keep them from doing a good job of oil control.

Even if this procedure doesn't help with the oil consumption, you'll have to do a lot less cleanup of the crankcase when you do an overhaul.

The one thing I'd add is to start with the engine up to operating temp before the initial drain & refill with the mix.

One quick check. Pull the PCV valve out of the valve cover & see if it has oil in the valve & hose. Sometimes these after market fancy valve covers have no baffils in them & the PCV system sucks oil out from the rocker arms.

I can count the 54 Chevy engines I've seen with a PCV valve in the past 60 years on the fingers of one hand! It was a very scarce option on anything other than a big truck.

pretty sure it is going through the engine. Lots of soot in exhaust.
