There are two other reasons for seeing excess intake or exhaust engine oil: 1. Worn valve guide seals. This condition will allow engine oil to leak down into the cylinders when the engine is shut off and not restarted for a few hours. The signs of worn seals are excess engine smoke at startup and a higher than normal oil consumption.
Removing and reconditioning the exhaust manifolds, NO gaskets, replace manifolds, and set the new bolts torgue. Run up the motor to operating temps and shut it down, till the next day..and do it again. Reset the torgue, run it up to temps..shut down...and for 4 days. That will set the bolts and manifolds and that will be that...for maybe 5 or 6 years.
On a FWC equipped engine, raw-water can still enter internally into the engine or transmission through raw-water cooled oil coolers. Raw-water can also get into the engine jacket through the main heat exchanger, as well as, enter the engine cylinders through leaky raw-water-cooled exhaust manifolds and exhaust elbows.
May 02, 2019 · 5. Temporarily secure the turbocharger to the engine exhaust manifold outlet flange with two bolts. Step 6: Rotate center housing . 6. Rotate the center housing, so that the oil inlet and outer pads will mate with the engine lines. The oil outlet (large hole) must be at the bottom with the centerline of the hole not more than 35° from vertical.
The turbo's oil drain tube is metal for the most part, the short section of rubber hose needed is nothing more than a coupling to join the upper oil return pipe assembly to the lower oil return pipe assembly. Likely get a suitable replacement for the lower oil return connector (coupling) at any autoparts supply house for far less than a dealership.
Hi guys! This is about OM642 in a W251 leaking oil from turbo into exhaust. I recently bought a 2007 Mercedes R-Class 320 CDI. Seller told me it sometimes smells exhaust in the cabin which it did. The reason I think is because the oil cap leaked, and oil went down to exhaust manifold. OR its...
The feed line going to the turbocharger leaks oil. This is a ongoing problem for many owners. The oil leaks from a woven plastic/nylon part connected to the metal part of the line. This could cause a fire as the oil leaks to an area where it can contact the hot engine parts.
If you aren't able to do that or simply don't want to your other alternative is to remove the turbo charger and put a plate (with a few holes drilled in it) over the exhaust manifold that puts backpressure on the engine to try and seat the rings.
