Cleaning out a muffler....question

Hey guys, just curious as to what ya'll thought. I've got the muffler off of a NH skid steer that is full of oil from a turbo problem.

So, my question is this. Short of running the machine until it stops smoking, what do ya'll think would be the best way to clean this muffler out and rid it of the oil inside?

I'm thinking if I build a fire in my burn barrel and lay it across the top it will heat it enough to clean it out. Either that, or fill it with a degreaser, and then rinse it out...........or maybe do both...........

Any ideas would be appreciated.
 
the 2 stroke Yamaha golf cart gets an oil build up in the muffler
from the golf cart forum I'm on it said to BBQ them or put them in a fire
I built a fire and burned mine out was about 5 lbs lighter
be careful the flames shot out both ends about 4-5 ft
in my case it took a cple hrs as it was pretty loaded and after the flames stopped shooting out and it cooled down I shook a whole bunch of garbage out
so if it's oil soaked I would bake it out some 1st
It'll take a lot longer bolted to the skis steer
putting a degreaser in it then burning may build pressure to fast and do damage unless you drain it good and air it out to dry it out good
 
We used to burn out 2 stroke motor cycle mufflers with the oxy/acetylene. Get a good flame going in and then keep the oxygen up, you'll get plenty of heat and make it glow red, but it cleans out the oil and carbon really well.

MY son just had a big time turbo failure on his Navistar 4300 with a 466E. We didnt do a thing with the muffler other than start it up. Didnt smoke much but sure made a big mess in the driveway and down the side of the truck. Getting all the debris out of the intercooler was a much bigger problem than the oil in the muffler.
 
I have burnt them out. Usually the oil will burn it self. I usually put some K-1 in the muffler to get the fire started and them light it with some news papers. They can burn for a good 30-45 minutes if they are really full. Then as soon as you can handle it blow it out the best you can with compressed air. Even a leaf blower works to blow the carbon out.
 
I was a truck mechanic until I retired,and have seen a muffler so full of oil from a turbo failure that I just went ahead and replaced it.It probably had several gallon thru it/in it.Oil just ran out of it.Some failures did not lose as much oil,and the muffler would be salvageable,but if it was very full/saturated-I would just replace it and not look back.Mark
 
I'd just run it. It will burn off after an hour or two. BT/DT.... Mine is an LS170 with the N844T engine.

take it to a machine shop and have it soaked in the gunk tank. that will clean all oil and carbon out.
 
How do these guys have so much turbo trouble. I had a million miles on my cat C-15 engine when I had to change it. That was only because it would not build any pressure. Could only get about 10-15 PSI on it. Changed it and now will get about 30 PSI. The only Turbo we needed to change.
