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"

I guess we all have our preferences on what works best for us. and no, that was not in the training. but I am certified in automotive,not agriculture or industrial. this is a method developed by the old schooler's way before my time. and it's a method that still works today and many still use it. repairing leaky crack's in the differential housing's on a brand new car under factory warranty with JB weld is not in the training either,and there was quite a run on the cracks too on the Mavericks and Granada's but that's what Ford had us doing in 1977 at the dealer,and no comebacks either, what i have found in my years of turning wrenches is,if you just stick to the book you will never learn the tricks of the trade,it's the seasoned tech's that teach the newbies out of technical school the tricks of the trade and to use other ways to make repairs as most people cannot afford to have the vehicles or tractors fixed by the book.just when I was a automotive electrician, I did not have any customers that would go by the book and replace a defective wiring harness. too much money,so I repaired or patched the harness,depending on the customers budget

Well I have turned the wrench for over forty years overhauled 1000s of engines never used abrasives to seat Anything. I use a light oil not engine oil usually marvel oil
Stuff gives enough lube till running and engine does the rest no smokers no boom boom no blow by
They run as long as customer lets them

we all have our preference's on what works best for us,me,when I charge an A/C after repairs are made I always charge from the high side. most tech's charge from the low.

There are manufacturers that use abrasives in the engine cleaning process. One is BMW with their walnut routine to clean the valves.

A question for the OP. How long a warranty did this guy give you ? I,m thinking he is trying to push you along with lies til the warranty is over. Whoever the guy was that tried to do these repairs for you is a quack. Hopefully you haven,t paid him any money, and take it to a real mechanic. It is the only way to properly fix this mess that you are in.

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.

All the while charging the customer “book“ time while tricking their rides?

Yeah, walnut blasting the intake ports and backside of intakes valves is an accepted best practice for higher mileage GTDI (gasoline turbo direct injected) engines, some of which are more problematic for carbon-buildup than others. But this is a targeted cleaning operation, intentionally using walnut shell media because it's the most gentle available. The cylinders are done sequentially with the engine turned over to make sure the valves are CLOSED, so you dont get any garbage into the cylinder, then it's all vacuumed out to keep the engine internals pristine and clear of foreign material.

A somewhat reluctant compromise to keep a specific area of the engine clean after high miles - very different notion than intentionally dumping abrasives into a running engine to purposely accelerate wear on all internal metal components.

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.

The engine in my Focus RS is a dry intake so I have to clean it every oil change (even though I have a 'catch can' on the EGR. I use Sea Foam top end engine cleaner injected directly into the intake pre throttle body but post ECM. Does fine and the Sea Foam top end cleaner comes with a curved injection straw as well. Takes about 7 minutes total. I can always tell it's getting time as my average fuel mileage drops off from 40 to 37. I also change the air filter every 2nd dose as well and I change the oil and filter every 5K additionally. Oil is cheap even today. So are filters.

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

Either that or a dead tractor...lol

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.

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.

You've got to be kidding!

 

[Ronald G]

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.
