I also posted this on pp however I usually get better responses here.
I recently rebuilt my 2.7l. I have the engine on a test stand. The oil tank is mounted at approximately the same level as it would be in the car. I am questioning the actual oil level in my crankcase. I put 12qts in the tank. I cranked the engine without ignition to get the oil pressure up. The dipstick doesn't show any oil so I put a couple more quarts in and it still doesn't show on the dipstick. I suspect there is actually too much oil because I can see a little bit of standing oil in the cylinders with a scope. It is not oil from assembly cause it was a different color. I am using a used 911 oil tank from an unknown engine. Normally I would just wonder if my dipstick was just not correct however since the setup is on a test stand, I wonder if something else is going on and I would like to verify the oil level in the case before starting the engine. How can I do that? |

How can I do that? With my 911 the first start of the year was always smoky. The oil seeps out of the tank and into the sump. It is really only a dry sump if the scavenge pump is running. You can get some check valves, but I would rather not. At any rate once the thing is running the scavenge pump sends any extra oil into the tank, the fire in the cylinders burns off what was past the rings and you get a nice level in the tank at idle. At least that is how I understand it. Since I fabled the tank and use a 911 dipstick, I am not as precise as I would want. I can find oil on my dipstick before starting but it comes up farther once running. |
