CAT 3196
On the raw water pump there is an oil fitting on top with a short hose. Mine appears to be leaking oil right at the fittings junction to the pump but I’m not sure. It seems to leak only at high rpm/pressure underway and sprays everywhere - not a lot but makes a mess. Ideally I need to get into the engine room underway but have not had the chance yet. However I did replace both the fitting and the hose but same issue. Any ideas, thoughts?
