@ Petah78 if you look around your valve cover / timing cover do you see any different coloring of RTV? |
They have always used different coloured sealant on different parts of the engine. The colours designate sealants with different properties (i.e. heat resistance, adhesion, flexibility, etc). The whole reason they are different colours is so that they don't get used in the wrong application by mistake.
Keep in mind that the whole engine is sealed with this stuff not just the oil pan and timing cover.
