Oil Consumption on 4BW

[SladeX]

Way too much consumption. I swapped my break in oil at 2350 miles and got back around 6.8 quarts. Dip stick pretty close to the level I measured prior to draining the oil. That oil is going somewhere, if its the exhaust, it should show up on the tips as wet oil. I had oil seeping into the cylinders via bad valve guides and my tail pipe soot was oily. Oil consumption was severe at that point before I got replacement heads. I lost a catalytic converter as well from oil contamination.

Check the coolant if it's mixed in there. Check if there's drips on the driveway. That much oil consumption doesn't just burn off cleanly.

Check for soot on your exhaust tailpipes. My Shelby did not make any actual smoke but it seems the piston rings never seated and oil was in the combustion chamber and got burned up and turned into soot. I think Ford lost lots of money on it, as lots of people had engines replaced. But the second one was fine. The 992 GT3 are having valve lash caps coming off, and the valve shim gets into the oil pump…. locks it up and boom goes the engine on a 300k car…

Now that I'm thinking about it, there is quite a bit of black soot on the tail pipes. I'm at the dealer now so I'll let them know.

That's where it's likely going then. You'll want them to verify health of the catalytic converters too; just because they work now doesn't mean that catching this much oil, burnt or otherwise, isn't taking life out of them
