If you see this amount of oil in one area I suggest cleaning the entire area down and monitoring the leak to pinpoint where it may be coming from. This 2013 Ranger PX shows a possible timing cover oil leak. Unsealed 4×4 Ford Ranger 3.2 Timing Cover Oil LeakĪnother common problem that shows up on the Ford PX Ranger 3.2-litre is an engine oil leak around the front timing cover area. The test involves pumping fluorescent fluid into the EGR assembly, pressurising the EGR to beyond its normal operating pressure and checking for leaks with a fluorescent light. Unsealed 4X4 magazine mentions a specialist workshop can test the EGR cooler.Ī specialist workshop will be able to test your EGR to see whether it’s leaking or not. The EGR cooler set-up is similar to manufacturers of vehicles that use the engine’s coolant to flow through an automatic transmission heat exchanger and if it splits, corrodes or cracks the engine coolant mixes with the automatic transmission oil. Major engine damage, like a cracked cylinder head or bent piston connecting rods. The common problem is the EGR cooler is known to split internally causing coolant to leak externally and worse, internally into the combustion chamber causing hydrolock similar to what happens when you try and start a flood-damaged car. An inlet and outlet hose is used to cool exhaust gases in the engine. For those who don’t know EGR is an acronym for Exhaust Gas Recirculation and sits at the back of the engine with 2 heater hoses connected. ![]()
