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? |

I did have the oil pressure circuit modification done by ollies. The oil pump was new. I was able to get about 23 lbs of oil pressure by cranking the starter for a little (no ignition or fuel hooked up).
As far as the oil in the cylinders goes, I had cranked the engine a few times to make sure I could get appropriate oil pressure- then I went on vacation so the engine sat for a couple weeks. When I returned, that is when I found the standing oil. I think that I was relying on the dipstick too much. I am thinking that I just need to drain the oil as though I was going to change the oil, then put about 6-8 qts back in, run the engine then check the dipstick. What is the oil console? I tried to follow the info that I found in a different post regarding relative height of the oil tank. I supposed there could be something wrong with the height of the tank. |
