I think it's a cracked oil pickup tube.. Drop the oil pan and have a look, the oil pan gasket on common blocks like yours is a re-useable rubber one. You can just bolt the pan right back up when you're done with no problems. Anyways, the pickup tube probably has a crack near the top, so it just sucks air unless the oil is up high enough to cover the crack. There's also a chance the o-ring where the pickup tube meets the pump is missing.. That'd cause the same deal.. I believe TU sells new pickup tubes.. :)

I just changed the oil and filter for the 1st time in my recently aquired '91 Daytona Shelby 2.5 T-1 and to my surprise drained 6 1/2 - 7 qts. out! I filled it with 5 qts. and put on a new Mopar filter and now I can't get any oil pressure on my mechanical gauge with the engine running. I took off the filter to try another one and found not 1 drop of oil in it! I took off the anti-drainback valve and it's working properly.What gives? Finally I added another 2 qts. of oil to make a total of 7 and now I have oil pressure. Could someone have removed the balance shafts or have a 2.2 pickup with the 2.5 pan? Could the oil pump be going bad? The engine has 70 lbs. of pressure @ idle when cold and it drops to 20 lbs. when at operating temp. and goes up to 40 lbs. when I rev it up so that seems normal. If the balance shafts were removed is there any way that I could tell without pulling the pan? The pan is slightly smashed in near the drain plug so could this be causing the problem? Also, I'm trying to sort out the vacuum line mess and noticed a hose coming off of a nipple on the turbo oil drain pipe and it runs to the breather in the airbox. Is this factory? If I come to find the balance shafts were removed and the oil gallery hole is drilled,tapped & plugged, then can I fix the problem of too much oil in the engine by simply putting on a pickup and pan from a common block 2.2 T-II engine? Any help or advice would be greatly appreciated, RICK -----------------------REMOVE-FOOTER-WHEN-REPLYING---------------------------- Questions?
