Burning oil when switching to 8 cyl mode
#26
This sure seems like excessive crank case pressure is the cause when in DoD mode. If simply turning DoD off fixes the problem
for the majority so all 8 cylinders are seeing positive pressure in the 4cycl process then it really seems like the crank case
needs to have a low dynamic pressure so oil is not being pushed by the "slack" rings on the deactivated cylinders.
So far my car is not consuming any oil between changes and I hope it stays that way but I am keeping a close eye on levels.
Looking around on the net I see on a corvette forum guys with Ls1, Ls2 and Ls6 engines have seem large oil consumption issues as
well, to the point a couple of after market companies are selling products to deal with the issue and it is all a venting issue on their end.
Its definitely something that needs to be dealt with, because oil in the cylinders can for sure cause a list of problems.
Has anybody made any efforts to inspect all their venting valves?? just curious.
