What happens if you put too much oil in diesel engine?
Specifically for a diesel, however, excess oil in the crankcase can cause it to be forced up past the piston rings and into the combustion chamber. In a SI engine, this simply generates, smoke and might foul the spark plugs. In a diesel, however, this oil becomes an uncontrolled auxiliary fuel supply.
What happens if you put oil in a turbo Chra?
You are not going to damage a tool steel piston ring with a little oil. There is actually no oil pressure against the seals. What happen is the turbo CHRA got flooded with oil and had no where to go but out.
How does oil get out of a turbocharger?
Well, it’s as simple as blocking off the oil return line on the turbocharger. The return line is connected to the crank case. The piston blow by back tracks up the return line. It will then push oil through the seals. And the seals are more designed to keep turbine and boost pressure out of the crank case. Do You Have Questions?
What to do if you have a bad turbocharger?
If there is a low engine oil level, excessive oil consumption, oil leaking into the induction or exhaust system, excessive oil in the PCV bypass hose, or excessive smoke or oil leaking at the tail pipe, verify the proper engine oil level and perform an inspection of the entire engine, checking for any aftermarket devices or custom modifications.
What causes excess oil in the exhaust system?
The excess oil will increase the oil system pressure which can force oil past the turbo’s oil seals into the intake and exhaust systems, and it can also overflow though the breather system into the intake manifold.

What kind of seal is on a turbocharger?
Just about all seals are steel piston rings. Some have carbon seals on the compressor side. The carbon seals are originally for draw thru carburetor systems, low mounted turbos, and high pressure crank cast systems. Carburetors would have a high vacuum on the compressor seal. That in return would pull the oil out of the turbocharger.
What do you need for a turbocharged exhaust system?
A turbocharged system requires two adjustable pressure-release valves in order to avoid over-boosting and management of pressure limits. This includes both a wastegate (WG) and a blow-off valve (BOV).
