The short version:
I have a old 914 FP race car that is "this close" to having the /6 conversion completed. The engine is a 2.4 911 T with carbs. All new -12 areo quip lines, new oil tank, thermosta, and remote oil filter console. Car is at Brad Mayuers shop.
Here is the issue with everything hooked up Oil will build up in the crank case to the point the oil tank starts to suck air and the over flow tank fills with oil. When drained, over 1 1/2 gallons of oil comes out of the crank case. Now with the remote oil filter, oil cooler and such bypassed and the line connected back to the oil tank the oil flow is better, not great, but better. When drained about 3 quarts of oil comes out of the crank case. Seems to Brad that I have a scavage pump problem, yes? Is there anything else that we should look for? If Brad is stumped, then I sure the hell have no clue.
I will not take this engine apart. If it comes to that then my /6 project is done for a while until I build up enough funds to get another engine.
More info:
What type of oil tank? You mentioned remote filter etc. Describe your system as best you can for us. It makes a difference.
If you have a cooler, there should be a thermostat that bypasses it until needed. Your remote components might be funky? The oil tank could also be an issue.
take the sump plate off and have a look see, at the the pickup tube on the pump
Brad Mayeur is one of the most experienced Porsche guys in the Mid West. You have taken it to the right shop for maintenance. I would not rule out the engine yet. The guys on this board will provide info and advise.
What exactly is Brad telling you??
Brad is telling me he doesn't know why this is happening. He feels it is the scavage pump, but isn't 100% sure. I trust Brad & Michael.
Well in basic principal either what ever pushs the oil out of the motor (scavange pump) is not working or there is a blockage in the oil passage going to the oil tank.
Maybe drain the oil lines from the motor exit to the oil tank and see if you can push air thru them. Would it be possible to have a defective thermostat or something?
Not to state the obvious, but do you have the sump plate in the correct orientation,the drain plug can't be under the pump pickup. Just a thought.
Cheers
Might not be the right oil tank? Last 4cyl engine wasn't really a true dry sump like the 6cyl is. They need a rather large pick up line.
Others have mentioned the pick up tube. I would check that as well.
