V6 oil Consumption
I might as well as add my .02 and say what we have found at the dealer
regarding this matter. First of all the problem is probably not the
vales/guides/seals. These components are very high quality and only give
up when pistons meet valves. The problem is the rings. The rings used in
the AAH/AFC seies engines (all V6's 92-97) are a low tension design for
less internal losses due to friction. This inherantly will allow a
slightly higher amount of oil to get by then in a I5. On cars with
consumption of 1qt every 1k-1.5k we remove the heads and pans. Pop the
piston and rod assy's out and 90% of them have the ring gaps lined up on 1
or more pistons. This what allows a high amount to get by the rings and
burn. WARNING: All this oil winds up in the cats eventually causing
failure (very common). Also all the engines that have been run low on oil
show a significant amount of wear on the bearings, showing scuffed through
to the copper. So if your V6 is using oil amke sure the oil level is
topped up, don't run a qt. low because it "seems" to have stopped there.
If the car is still under warranty talk to your dealer about this. When we
do the repairs we replace rings,bearings (rods/mains),valve seals and any
other gaskets needed. We also hone the cylinder bores before reassembly.
To date no engine we have done this to has returned using any perceptable oil.
