Detroit 6-71 wet stacking

You mean to tell me those Detroit’s at high idle aren’t music to your ears!? A fine tuned Detroit is like listening to Beethoven.

Beethoven on drugs maybe

I still think one of the best sounds was from the 12V71N in the old Wabco B-70 scrapers, they had the Nelson manifold mufflers and a set of 5" pipes through the hood. They did bellow, but it had a mellow tone to it. And yes I sat on several of them for a few hours.

This song here was Beethoven's original version, hidden away for century's until Jeff Lynn of ELO found it in archives. Much better to listen to than a two stroke chevy. Beethoven was a ROCKER.

Good thing Chuck Berry came along when he did.

Well, blower was redone and still leaking oil into exhaust. Not sure what to do now. Engine runs great though

Next suspect and only likely remaining, Is nothing else beyond rings that will do this and Not runaway.

Throw some STP in it.
You'll be fine.

Was thinking sprinkle tspn. Bon Ami in the intake at High Idle!!!

You have severely worn oil control rings on one or more cylinders. Lucas oil stabilizer will help diminish the issue.

Interesting thought ... in attempt to re-seat the rings I assume?
I've done that with a tspn. water to break up carbon build up ... helps stop engine from dieseling. But that trick needs to be done on a cold start.

Long ago unscrupulous used machine sales people would do this, I was being facetious.
The old tricks were Bon Ami or Comet cleanser in the throat of a running engine to minimize oil use and blow by, banana peels and sawdust in differentials to quiet worn gears, 140wt gear oil in sloppy manual transmissions, all automatics got Type F to make the clutches grab better.

Were others I found on purchase inspections.

saw dust and banana peals in rear ends, I do know that a small block chevy likes pieces of Oreo's at 3,500 rpm.

a foot of fresh snow and still falling; 150 mi away from anywhere and all ya got is what is in the truck one would be supersized what one can come up with just to get home.
panty hose for a fan belt. ... if it is just one leg wouldn't that be a panty ho?
hand operated the voltage reg.
tie-wire for a carrier bearing - summer time
coffee can for exhaust to get through scales
black tape heater hose to get to town
and on and on

1956 International in a snowstorm with a busted fan belt. 2 rubber rings from 5 gallon bucket lids around the fan, crank, and 6 volt generator. Limped 25 miles home at 20 miles an hour but I got there.

Pulled the double, chain side wheel bearings out of my XR600 Honda race bike and used with a bolt thru them in place of the bad bearing on the idler pulley on the serpentine belt tensioner on my box van. Made it all the way across Montana on a holiday weekend with nothing open with parts.

I thought I read on here that there was a Cat procedure and part number for bon ami for rings that failed to seat. (failed to seat is different than worn out)

To properly decarbon an engine, it has to be up to operating temp, and use a garden hose, light shower nozzle...

Are several 'Contestable' or questionable processes of years gone by that actually worked, they got edited out of the repair guides as the people that used them got out of hand with them. IE Gasoline for fuel gel control was in the Older Detroit manuals, no more than 5 gal to 100 of unleaded regular gas with a chart for mix rates against temperatures. All too many read/heard the first sentence then made a second mix without using as much fuel as possible and overloaded the diesel with gas as just mixed 5/100 and ate fuel systems up. The Bon Ami was in really early IHC manuals I remember as to seating Chrome Rings that would not seat and were using serious amounts of engine oil. My one boss had that manual for the old V478/549 series where was printed in it. And was "One level tspn sprinkled in the intake at 1500rpm Until severe smoking abated". Supposedly aided in seating stubborn valves as well but detracted on longevity per the boss.

The Bon Ami trick was widely used years ago, and like DM said with chrome rings. Those could be troublesome trying to seat.

Yes there was a Cat part number for it at one time! If I can find it I think I had an old manual that mentioned it.

I have seen high oil consumption through leaking/loose wrist pin retainers although it is not nearly as common.

Seen a couple of runaways due to badly installed wrist pin seals!! 53s were the worst for that.

Back when I worked for Terex dealer, we always checked the wrist pin retainers with a vacuum cup. We had a guy that built engines that was ALWAYS afraid to do an initial fire off of any Detroit he built. He had a few runaways and was gun shy as hell. He would build an engine and spend hours going over everything 3 times or more trying to convince his self that it was good to go.

OK.....I'll admit some of his paranoia was caused by some of us in the shop screwing with him. LOL NEVER show a weakness around dudes in a shop. Things like pouring a half-quart of fresh engine oil under the engine he was running when he took his lunch break (we let him spend the last half of the day scratching his head trying to figure out where the oil came from)..... or another time he was running a new build, turned away from the engine for a few seconds and then some jack-off starts hitting a metal table behind him with a hammer( he almost broke a leg stumbling for the stop lever).......or another time when he saw a shop rag blow out of the exhaust on a fire up (stuffed in the port by another field tech).
I just cant believe there are mean people in the world like that! Good times back then!!!!
