Nissan Vg33e #6 cyl valve-stem seal replacement.

This is the most difficult of all procedure. This is how to stop smoky tailpipe exhaust from burning oil. Stop that light blue smoke emitting from vehicle exhaust tailpipe. save the with good emmision. this would the same procedure for most Single OverHead (SOHC) engine and or with push-rod valvetrain engine. This show replace the valve stem oil seal for the Nissan Vg33e or Vg33er cylinder and valve. The exhaust valve spring and retainer with keeper() is one of the most difficult valvetrain component to remove, with valve spring compressor(hand) . See how it is done by most . and valve stem seal are most likely to leak oil into the combustion chamber since it seat at the lowest part of the cylinder head for return oil flow to the sump. High mileage engine will must likely develop large amount of sludge along the cylinder head under the valve cover. This is due to clogged PCV(Positive Crankcase ventilation) valve or not following oil change interval recommendations. The sludge develop around the valve stem seal where it seat or mate with the valve stem is cause of damage and burn valve stem oil seal. the sludge can also prevent oil control to lube the valve stem in its valve guild causing excessive wear and tear to valve stem guilds. It is highly recommended that a engine oil flush additive solution be all to engine oil before changing old engine oil. the oil flush additive solution will help clean the sludge away to minimize poor lubrication.
