prevent glazing

what can be added to Dieselfuel to prevent glazing in the tractor engine bore.

What engine is it and what is it being used for? It might be more of a problem with excessive idling and/or not being worked hard enough or running too cold. Modified pulling tractors use water injection.

Nothing you can add to fuel will prevent "glazing". Simplest thing to do is work the engine so that it gets up to temperature. Pull a plow, bushhog, or an hour on a dyno at pto speed.with a 80-90% load on it.
Years ago Caterpillar used to sell a product that would break the glaze on slow running diesels in draglines,cranes and power units that just loafed along at 1/2 throttle and started to slobber . You removed the air filter and dusted alittle in with the engine running 3/4 throttle. It was a very fine abrasive basically "comet" or "ajax"

I've heard of old time mechanics dusting some Bon Ami in rebuilt engines that the rings wouldn't seat. Never done it myself, would be afraid of ruining something.

If your talking about the bore and rings getting glazed and causing the engine to start slobbering oil, then BonAmi is your best bet. Like others have stated CAT used to recommend it for seating the rings in their engines when all else failed, and if you look in the right, old manuals, they even had a part number for it. Heck, if I remember right I actually saw it in one old manual called for by name.

Personally I've done it only once, but it worked like a charm. I rebuilt the engine in a specialized 165 MF that was used more as a power unit than anything else. I have no way to dyno and break in an engine, so I told the customer to get her warmed up, then 'pull her ears back and make her grunt' for the first few days. They didn't do it, let it idle along like normal, and within a week it was slobbering oil out the exhaust. I went down, removed the air filter, and with the engine at wide open throttle I sifted about two tablespoons into the airstream, replaced the filters, and then just let it run for about 20 minutes. With it already hot I watched as the oil that was slobbering out the exhaust stopped about 5-10 minutes in, and then what was already in there started burning off. That was about 4 years ago and it has never slobbered any more oil since, and it still starts and runs like a new one, regardless of the outside temp. In other words it still has good compression so the BonAmi treatment doesn't appear to have hurt anything but did take care of the glazing problem.

Beyond that all I can say is good luck, and like anything else, your milage may vary, but it worked for me.....

There is no such thing as a 23C 3 cylinder Perkins. It's either a Standard Motors 23C 4 cylinder or a Perkins A3-152 3 cylinder. The perkins is a superior engine. Is it slobbering or not running right? Maybe the injectors need to be checked? If it's a 23C they are known to be hard starting if that's the problem.

at the moment not able to edit my post!

so thanks for correcting my mistake. its as you said Standard Motors 23C 4 cylinder or a Perkins A3-152 3 cylinder.

I have heard talk of the Bon Ami treatment years ago. I never had the nerve to try it. Will tell you what a guy did years ago when his new IH 560 diesel was using oil. He took the air cleaner hose off for a round or two in the dusty field and claimed that sealed it up. He was telling me this many years after he did it. He does things out of the ordinary quite a lot though.

In 72 I was working for a guy in Marshalltown. After the heavy spring work was done he traded an 806 for a new 966. All it did that year was rake and haul hay, cultivate at half throttle and then haul grain in the fall. In the spring of 73 when we put it to work, it was using twice the oil that the old 806 had. He complained to the dealer. Their solution was to hook it up on the dyno, cover part of the radiator so it was running about 220 degrees and work the snot out of it for 24 hours. That seated the rings and it didn't use oil any more. I believe they said that they were chrome rings and had to be worked hard as soon as possible to break in correctly. Another guy we knew from the next town north had also bought a 966 and it was also a oil burner. They gave it the same treatmen and cured it. The only thing bad said about the 966 after it was broke in was we couldn't find him chopping corn in the mile long hilly fields as it didn't send a plume of black up over the hills as the 806 always had.

Well which one is it? It can't be both. I know the Perkins in my 135 will smoke more if it has been just putzing around but clears up when I work it. What is the problem you're having?

biggest thing is you must run the engine at operating temp. when an engine is run cold it can produce glazing.

it could be any diesel engine but i pick the 4 cylinder Standard Motor Company 23C diesel engine and the 3 cylinder Perkins A3-152 or the 3 cylinder Perkins AD3-152 diesel engine
