Nissan Navara Oil Leak Malaysia — YD25DDTi
Common YD25 oil leak points: valve cover gasket (rocker cover), turbocharger oil return pipe, and rear crankshaft seal. Diesel engines under higher compression are more prone to seals hardening over time. Turbo oil return pipe blockage causes oil to back up and leak — check the return pipe for carbon deposits. Address leaks early to prevent oil contamination of the timing chain area.
