Disconnect the battery. 2. Raise the vehicle. 3. Remove torque converter or clutch housing cover and inspect rear of block for evidence of oil. Use a black light to check for the oil leak: a. Circular spray pattern generally indicates seal leakage or crankshaft damage. b. Where leakage tends to run straight down, possible causes are a porous block, distributor seal, camshaft bore cup plugs, oil galley pipe plugs, oil filter runoff, and main bearing cap to cylinder block mating surfaces. 4. If no leaks are detected, pressurized the crankcase as outlined in the section, Inspection (Engine oil Leaks in general) CAUTION: Do not exceed 20.6 kPa (3 psi). 5. If the leak is not detected, very slowly turn the crankshaft and watch for leakage. If a leak is detected between the crankshaft and seal while slowly turning the crankshaft, it is possible the crankshaft seal surface is damaged. 9 - 1232 ENGINE - 3.7L SERVICE INFORMATION WK |
