  Q: How to service and repair the oil pan to prevent engine failure on Mercury Montego?

  A: A clean working environment is essential for oil pan repair because foreign materials can lead to engine failure. Start the service by hoisting the vehicle while it maintains NEUTRAL gear position. Detach the front Catalytic Converter and its bracket through the removal of two bolts. Reinstall the drain plug after draining the engine oil and tighten it with 26 Nm (19 lb-ft). Clear away the old oil filter before proceeding to uninstall the torque converter lower inspection cover. Remove the set of 2 oil pan-to-transaxle bolts and oil filter adapter-to-oil pan bolt. The 15 bolts fastening the oil pan need removal while getting rid of the gasket. Installation of the new oil pan requires plastic scraping tools instead of metal scrapers or abrasive tools. Clean the sealing surfaces with an appropriate plastic tool before applying a silicone sealant with a 10 mm diameter dot to the required areas. Install the new gasket onto the oil pan and attach its bolts and stud bolts loosely before tightening all oil pan-to-transaxle bolts to 40 Nm (30 lb-ft). You must perform bolt torque according to the specified order when securing the engine-to-oil pan bolts with a torque setting of 25 Nm (18 lb-ft). Fasten the adapter bolt between the oil pan and filter adapter with 40 Nm of torque force before turning it by 90 degrees and repeat the process. First install the new oil filter by tightening it to 16 Nm (12 lb-ft) then proceed with installing and tightening the front catalytic converter bracket along with its 2 bolts to 40 Nm (30 lb-ft). The last step involves putting back the front catalytic converter and pouring clean engine oil into the unit.
