Customer Question

I have a cat to 226b Skidsteer.
Ser# *****
There's a ton of oil smoke coming out of the exhaust.
It only has 2600 hours on it.
Is there an oil line running through the turbo that could be putting the oil in the exhaust?
If so is there a seal kit ?
There is oil dripping from the exhaust pipe.
There is less smoke when the engine is cold .
I'm hoping the rings aren't bad .
What is the best way to diagnose this problem?
Thanks
Kevin

Do you have a diesel compression check kit?
Customer: replied 7 months ago.
I think I can get a hold of one
Customer: replied 7 months ago.
Looks like I have a diesel leak down kit, so that should work.
Is there a way to test the turbo?
Expert:  Bradley Martin replied 7 months ago.
Not without pulling it off and and inspecting it visually for signs of oil contamination
Customer: replied 7 months ago.
So what should I do first
Expert:  Bradley Martin replied 7 months ago.
I would check compression first
Customer: replied 7 months ago.
What should the compression be
Expert:  Bradley Martin replied 7 months ago.
What is your serial number?
Customer: replied 7 months ago.
It's at the top of the page
Expert:  Bradley Martin replied 7 months ago.
ok I see it sorry
Customer: replied 7 months ago.
No problem
Expert:  Bradley Martin replied 7 months ago.
Should be around 426 PSI
Customer: replied 7 months ago.
Ok
I will be checking it Monday or Tuesday and I will get back to you then thank you
Expert:  Bradley Martin replied 7 months ago.
Ok and your welcome
Customer: replied 7 months ago.
so I cant find a compression tester here on maui that goes over 300 psi.
but, today I pulled off the turbo and the exhaust manifold.
I really cant tell where the oil is coming from because the exhaust ports all seem to be dry.
even he turbo didn't look exceedingly wet.
what do you think?
Expert:  Bradley Martin replied 7 months ago.
I think your probable cause is a head gasket issue that would cause oil to get the exhaust and smoke
Customer: replied 7 months ago.
Wouldn't I have oil in the intake side too if oil was getting in to combustion chamber?
Don't you think I would see some oil in the manifold?
I need to be sure.
Will the 300 psi comp tester help me in any way?
What about the 100 psi leak down tester?
Expert:  Bradley Martin replied 7 months ago.
Yes the 300 psi gauge will work to see if you have low compression just dont max it out and the 100psi leak down tester I have not used one of those before so I could not tell you if that will work also check your rocker arm seals on each end of the valve cover make sure they are not leaking
Expert:  Bradley Martin replied 7 months ago.
Are you sure it is oil coming from exhaust and not fuel?
