good afternoon all.
my engine loses oil noticed by drops in the dip stick level especially after highway runs approx 80 kms each time
i own a Navara AX ZD30DDT. it has 230 000km on it. full engine overhaul at 215 000 km with all nissan original parts (new pistons, rings, bearing rods, head, the works) done by a ceritified nissan tech at the local dealer. ( because thermostat got stock and the head cracked)
stock turbo and exhaust. blanked the EGR.
oil change every 5000km. i use a 15W40. (recommended by the nissan dealer for our tropical climate)
after a highway run i noticed a drop in the dip stick level and after 2 weeks time of highway runs 80 km daily the dip stick dropped by half. took 1 and a 1/2 quarts to top up. this problem continues.
so far i have searched everything in the exterior for oil leaks with no luck. have also dismounted and inspected turbo and housing for leaks. nil leaks.
no oil noticed in the exhaust nor sooth in the exhaust pipes. no noticeable blue smoke, black smoke nor white smoke.
any help or suggestions for further investigation is kindly appreciated.
thanks
