353 detroit smoking more then normal?

logman81 · January 15, 2014, 02:17:38 PM

No more oil leak! Now there no leaks at all!

logman81 · January 15, 2014, 02:43:41 PM

And now it's not smoking heavily anymore? All I did was change the oil pan gasket and put fresh oil in. Took it for a ride around my property and only a little smoke almost none, load or no load couldn't get it to smoke!

Oil could have been fuel diluted,my friend had a chipper with a four cylinder Cummins,was smoking like the devil and making oil after he had a injection pump put in,i pulled the injectors and had them tested one was shooting raw fuel no atomization at all,replaced injectors now no smoke,not making any oil,running great.Keep an eye on the oil.Not trying to scare you but if your shooting raw fuel into a cylinder will develop a hot spot, i've seen them burn a hole in the piston.

As I mentioned before when I drained the oil it didn't smell like diesel fuel. It must have been a sticking injector and finally freed up.

Dave Shepard · January 17, 2014, 06:50:17 PM

Did you add any ATF or anything to the fuel? I guess it makes sense that it could have just been a sticky injector that needed to be worked loose. Sitting doesn't usually help machinery.

logman81 · January 17, 2014, 07:32:35 PM

Yes I did it probably helped, the temp was also warmer this week to. Hopefully it is fixed will have to see once I get the chance to run it more.

logman81 · January 30, 2014, 11:38:21 AM

Hey guys still trying to figure out why its smoking. I just pulled a sample of fuel from the tank , pretty nasty looking it even smells a little off. Could the smoking be caused by old nasty fuel? This machine has been sitting for a few years with what was in the tank and I've been running it with what was in it when I bought it. I'll post a pic .

logman81 · January 30, 2014, 11:43:29 AM

here it is nasty ! Be nice if that was the cause of the problem.

beenthere · January 30, 2014, 11:48:46 AM

Seems fuel would be the first thing to check, and replace with fresh, on an engine that has been sitting for any length of time.
Now that gunk is throughout the entire fuel system.

Are your plans to eliminate that fuel as the cause of the problem?

logman81 · January 30, 2014, 12:20:43 PM

I'm not sure if it is the cause or not but I don't think it's helping either.

mad murdock · January 30, 2014, 04:56:48 PM

That is some ugly fuel, LM81. I am sure it will go a long way to making the issues go a way once that fuel contamination is taken care of.

logman81 · January 30, 2014, 06:10:09 PM

Ya some nasty stuff for sure !

David-L · January 30, 2014, 07:29:28 PM

Logman 81, Google up diesel cetane rating and unburned fuel due to poor ignition sounds like it cound'nt be helping That motor. Old fuel is made for brush fires.

logman81 · January 30, 2014, 08:43:29 PM

Ya that is what I think is the problem with to low of cetane .

sandhills · January 30, 2014, 10:08:49 PM

I'd start with the fuel ;). Drain her out and change fuel filters (at least once) not sure if the 353s have a sediment bowl but if it does clean that too, good luck and I hope the smoke issue goes away.

redprospector · January 30, 2014, 10:13:04 PM

I'd bet that was the problem. Hopefully it hasn't caused any other damage in the fuel system.
Detroit's are pretty much bullet proof though.

If I was you I would drain that tank and figure out a way to flush that tank out.... IMHO there is probably a layer of scum covering the whole inside of the tank... Now if this is the case picture what is happening in the rest of the fuel system.... It wouldn't take much of a piece of "stringy slimey goo" that is half loose inside a fuel line to block off the line enough under pressure to starve the system of fuel, hence your sputtering.... Old fuel is old fuel no matter which way you look at it. Look at what happens to gasoline that has sat for a couple of years in a steel tank out in the sun... The same can happen to diesel too especially if it had condensation in it prior to sitting. You have ran the machine and worked it which more than likely has stirred up this rotten fuel..... BTW does the exhaust smell foul compared to what a normal diesel exhaust smells like?
I bring up all this from an experience we had a few years back. We had purchased a Caterpillar D6C that had been sitting on the south side of stand of timber for several years. It was a mile or so trek for us to get to this machine without permission from a cagey ol neighbour that owned all the surrounding land.... We figured we could simply get the machine running enough to walk it out to the road where we would load onto lowbed. We carted a couple of jerry cans of fresh fuel and batteries and tools in with an atv and trailer... Needless to say long story short we ended up sucking the entire fuel system full of junk and had to replace the works... It took two of us over 3 days to get the machine to the lowbed. We used a lot of air in these 3 days to repeatedly blowing out the lines, what a PITA but the machine was worth it as it had LOW hours with an undercarriage with nearly 80% wear..... Brad.

logman81 · January 31, 2014, 08:36:40 AM

I hope that's all it turns out to be . Yes the exhaust does have a abnormal smell and so does the fuel in the tank. I won't be able to get to it till next week as I have a guy maybe interested in buying it. If he doesn't buy it I'll drain the tank then unbolt it and flush it out and change filters. I think we're on the right track now!

EricR · January 31, 2014, 10:06:17 AM

Just a thought, If you want to sell it, I would spend the few hours it would take to flush it out before you had people come look at it. a good running engine makes for better sale

Logman, get that brush fire going and feed it that fuel and a doughnut. ( used 15" car tire ). my neighbors love it when I burn brush.

logman81 · January 31, 2014, 06:14:04 PM

Ya I got a nice brush pile at the shop and I plan to drain out the old fuel and burn it.

The 285s off my Duramax work even better we use them and diesel to start our new years bonfire every year

logman81 · February 01, 2014, 12:42:51 PM

It's all fixed! I drained the old nasty fuel out and changed both filters and put fresh fuel in the tank. I started it an it smoked for about a minute and then cleared right up. Took it for a half hour ride and boy what difference runs so much better and smoother. And now it smokes only a little. So glad that's what it turned out to be and not an injector problem.

I am very happy that you finally got the problem licked.
I can't remember where I saw the following "Buy Clean Fuel and Keep It Clean " or something to that effect but clean fuel eliminates all sorts of engine related problems.
