The guy that put the engine internals together says "The rings are not seated yet end the smoking is normal. Just give it a couple hours of work"

on Diesel tractors, Agricultural & industrial, it is important to run a thermostat. if the engine runs too cool the expansion of the pistons and cylinders are not up to spec's from the engineer's design.it can cause premature cylinder -piston wear. we used to use comet or Ajax, pour a little into your hand, bout 5 table spoons and let the intake suck it up then let it run for a while. the rings seat in much faster. a old school trick and has been working for many years. put a 160 thermostat in it and run it for a few, then do the comet treatment if it did not clear up on it's own. 110 - 120 is way too cool. the cylinder and piston won't expand enough

This was an interesting thread from the beginning. Dumping an abrasive into the intake is one of the craziest things I've ever heard. I don't care how many folk have done it but it's interesting

Yup, but there may be others who stumble across this thread.

I have built a LOT of engines from lawn mowers to locomotives. It doesn't take much to seat rings. There is stuff missing from this story like a shoddy valve job. There are a BUNCH of reasons a 'fresh' engine could smoke and for some of them it will only get worse.

Any chance this was a spam thread from the beginning?

You can not just assemble an engine like you would a toy model kit. It is the mechanic responsibility to check clearances, rod,main bearings should be checked with plastie gauge for proper clearance. If you were there you would have seen this. Also ring end gap is important. Simple to check these important parts. Alot of other things I could could go over but I think you get what I"m saying. Sorry to say this but I hardly think that engine is going to somehow heal itself.

I recall a mechanic who rebuilt a tractor engine (International C) or the like. Baking soda was poured in the intake as a fine abrasive to help seat piston rings. End Gap. 0.004" per Inch of Bore.

This reminds me of the old Audi fans thread where a dude convinced everyone he stuck the intake of his new s4 in a bucket of sandblasting media, then revved engine to 5k for a few minutes to “port and polish” the intake. Then proceeded to ask for advice about why his check engine light was flashing and making terrible sounds. lol.

You've got to be kidding!

So you are saying that all cars and trucks made in the world will smoke until you work them a couple hours. Ha!Ha!
If I bought a new car and it smoked they would get it right back.
Sir you have a problem, dont buy anything from a backyard mechanic and please dont pour anything down the intake you will further destroy the engine.
Have a reputable mechanic disassemble the engine and reassemble it correctly.
