I HAVE A 2003 CHEVROLET SILVERADO WITH 80K, I JUST STARTED SLOWLY LOSING ANTIFREEZE, ABOUT A GALLON SINCE THE LAST OIL CHANGE OIL CHANGE, BUT AT THIS OIL CHANGE I HAD TO POKE A SCREW DRIVER IN THE DRAIN PLUG HOLE TO GET THE OIL TO DRAIN, DUE TO SLUDGE IN THE BOTTOM OF THE PAN, OIL FILTER DIDNT LOOK BAD, AND THE OIL PRESSURE WAS A LITTLE LOW BEFORE THE OIL CHANGE ABOUT 10PSI, BUT RIGHT BACK TO NORMAL AFTERWARDS. I HAVE NOT DRIVEN IT SINCE. HAVE BEEN TOLD THAT THE INTAKE GASKET IS PROBALLY THE PROBLEM, BUT FROM WHAT I HAVE READ ONLINE THE 5.3L HAS A DRY INTAKE. IF THAT IS TRUE THEN I FIGURE EITHER THE HEAD GASKET(S) OR IVE BEEN READING ABOUT MICRO CRACKS IN THE HEAD(S) CAUSING MY PROBLEMS. WHAT DO YOU THINK?
