I just recently had the engine built in my Shelby by a very reputable builder. The issue is that after driving for several miles the oil PSI gauge goes to zero, and the warning comes on the dash readout. There is no clatter from the valve train and the oil looks good on the dipstick. After it cools and is restarted the oil PSi is back to normal. I am assuming a bad sender. What other issues should I look for? Also what is the trick to change the sender on a car with headers?
