I had my 455 re manufacturied by S&J engines in Spokane a couple of months ago. I had roller lifters, roller cam and roller rockers installed along with oil restrictors. I had S&J install the intake manifold and all sheet metal. I figured this was the safest way to insure a good running engine without any leaks. Manny Trovao started the engine as prescribed by S&J, ran for 20 minutes at 2000 rpm. After 700 miles I changed the Joe Gibbs break in oil to Mobile 1 15-50 and left for Alaska. On the way to the Cascaders Covered Bridges rally I used one quart of oil every 140 miles! There was no smoke from the exhaust, plugs were not fouled and there was not any apparent oil from the rocker cover vents. The technician at S&J thought that it might be an intake manifold leak and suggested that the manifold be resealed. I convinced Jim Hupy to reseal the intake manifold after the Covered Bridges rally. I spent three days at Jim and Judy's house carefully removing cleaning and resealing the manifold. Used new Dick Patterson gaskets and block off plates. This surely would solve the oil consumption problem. I continued north to Alaska and after another thousand mile it was still using 1 quart of oil every 140 miles, no improvement. S&J suggested changing to conventional oil so I changed oil and filter to Shell Rotella 15-40 in Dawson Creek. Since then I have driven 2000 miles and have used two gallons of oil. An improvement from 1 quart/ 140 mi to 1 quart / 250 miles. I now have about 4500 miles on the engine and oil consumption remains constant at 1 quart/ 250 miles so. I just add oil and check the gas!

Think I'd run a compression check when I got back, Mr D.

It may just be because this is a forum and nothing good ever gets posted, only trouble, but I for one will not be getting a rebuilt engine or transmission until it is absolutely necessary.
Almost every thread I see where there is a problem it's "my engine's been rebuilt and it just fried again" or "new trans last year, stuck on the side of the road with a toasted transmission"

I have installed a number of rebuilt engines over the years. Some of them
were ones that I rebuilt, some were S and J, and other competent
rebuilders. Most of them are still in service, doing what they are supposed
to do. We probably don't hear about the ones that don't cause any trouble
very often. My original 403 in my 78 Royale is approaching 140,000 miles on
the clock, and has never been open. I replaced the original transmission in
2012. It worked well up till it didn't. My current Manny tranny has a trip
across Canada and back to Oregon, and a trip to Detroit and back via Route
66, and several trips to California and back. Seems to be doing well.
If your current engine uses less than a quart of oil per 500 miles, that is
pretty normal for engines that work as hard as these do. If it hits on all
cylinders, maintains antifreeze levels, drive it until it doesn't. Don't
fix what ain't broke.

Justin,
I hear what you're saying. We read many posts about rebuilt engines with problems, or rebuilt transmissions failing. I too do not plan on an engine or transmission swap until it is needed. However, that is what this forum is all about, helping people with problems. Although, I too would like to see some "good" reports posted as well, for encouragement for those of use who are fairly new to the GMC lifestyle. I'd like to see reports like; "50,000 miles on an engine rebuild without major issues...", or "successful 3000 mile trip through the mountains...", "Alaska and back with only a few less spare parts on board..."
I am looking forward to seeing the rest of your build Justin. Hopefully in person at a rally one day soon.
Safe Travels and keep your chin up,
Russell

Rick, we verified the fill quantity and the dipstick markings. Tried
driving it a qt. low. No difference. When it comes back from Alaska, if he
stops here, we will do cylinder balance and scope the cylinders. I suspect
valve seals, because it has a bunch of hot rod parts up there.

Did you specify Chrome rings? I had a hard time seating my chrome rings...my consumption was high, with no visible smoke for first 3500+ miles, it still uses oil, but far less than it did 2000 miles ago. Lastly , confirm you have the right PCV valve and baffled valve covers.

It has the correct valve covers and pcv valve, hoses, air cleaner, and no
sign of oil in those parts. I looked very carefully at this. It was my
first suspicion. Ruled it out.

I just had my engine rebuilt by Total Precision Engines of Ft Collins, CO.
At my request he installed the Comp Cams Magnum Roller Rocket Arms kit 249-1442.
I used break in oil for 100 miles and dumped it and at the builders suggestion filled with Brad Penn 10w30.
I drove to Shawnee OK and back for a total of 1750 miles including a side trip to Santa Fe NM. We pulled the Geo Tracker and went up steep grades on I40 entering NM and up Raton Pass from NM into Colorado. Very strong engine.
I kept checking my oil level and was surprised to find that I was not burning any oil. So I have driven 1750 miles without adding any oil.
With past engines I usually burned a quart every 500 miles.
I wonder if your oil burning problem is related to your passenger side valve cover. If you don't have the original it might not have the right baffle inside below the PCV valve. You might also have a faulty PCV valve. Try changing it and see if that makes any difference.
If you are using that much oil without any evidence of external leakage it must be getting into the intake manifold somehow and being burned and out the exhaust. Your spark plugs should show oil. Check them.
